I Don't see how you can say it was the tires since you replaced the tires and the shocks, have you put the old shocks back on to see if the VIB comes back with the new tires.

I replaced the shocks first and drove about a week before putting the tires on and the vibration was still there.  Also, I could tell over time that the stock Rancho shocks were degrading and the truck was becoming more bouncy, but the vibration was not affected.  I'm pretty positive the vibration in my case was due to the crappy stock tires, perhaps in combination with other design parameters associated with these trucks.  I can't be certain that it was all 100% the tires' fault but so far about a week in on the new tires I haven't felt any vibrations.  I'm keeping an eye on it though to be sure and will report back if anything comes up.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Wow, 799 pages to this thread.   And soon to be 800.    My brand-new 2018 Z71 has a mild shake at 110 km/h, felt mostly in the seatbacks and pedals.    Will report it at my next dealership visit.

Thanks for the clarification, I have a '15 2WD Silverado CC SB with the LTZ Z71 package, it has the Rancho Shocks and I have noticed a bit more bounce than it used to have but I have 75k on her at this point.

 

I did find out one thing, at least in my case the bed created a ton of vibes.. once I put a bed cover on it the vibs calmed 90% bet if I put new shocks it would be smooth again

I'm pretty sure my Ranchos were shot around 30,000.  I can guarantee yours are shot at 75k, no doubt, I'd bet my truck on it.  I know it's expensive, but order yourself some Bilstein shocks right now, get them installed, and drink a cold beer and smile.  No need to send me a thank you note either.  Just enjoy your truck!

I've been following this thread, as my 2016 midnight edition Z71 has had vibration issues since day 1.  I had the driveshaft replaced, added a bed cover, rotated and rebalanced tires multiple times, got an alignment, tried adding weight to the bed, and basically had no improvement with any of these fixes.  Vibration started around 70 mph and just got worse as I went faster.  Probably the worst was around 74-78 mph, and it felt like the truck was going to rattle apart.  The drive 35 hour drive to and from Colorado two weeks ago was AWFUL.  I tried driving 75 mph just to not lose time, but it vibrated so bad I eventually slowed to 65-68 just so I didn't get shaken so bad.

 

Now I might be crazy for spending money on a truck that has this bad of a vibration problem, but I had a 6" Pro Comp lift installed along with new wheels and 35" tires yesterday, and the vibration problem is totally gone.  I don't mean it's better, it is 100% smooth as glass all the way to 80 mph, much smoother than even day 1 from the dealer lot.

 

Just thought I'd throw this out there for anyone trying to find a fix.  It's not cheap, and it's not really practical, but it did fix my issues.

I bet a set of new rear shocks would have fixed your problem without even putting the lift on. Set of basic Bilstein 4600s has my ride smoothed out.  When I took the rears off it was very apparent which shock was bad. No damping at all for several inches of travel on it and no sign of leakage.  Those stock shocks are JUNK

I havent checked my old shocks but I do have them in a box.  I'll have to look and see if they were having issues.

That’s my thing... I just spent a ton of money on a truck and I’m getting the vibration. I’ve got a 2018 Sierra with about 1400 miles. My steering wheel was off, and got vibrations about 70 mph to 75. I took it in, and got them road force balanced and they adjusted the steering wheel. The steering wheel isn’t as bad (but still a little off) and now my vibration starts about 60-70 mph. It’s not a huge vibration but it’s there. Doesn’t seem like it’s coming from the front as much, as I can feel the seat vibrating. I’m going to take it to the original dealer and see if they can take a look. I travel on the highway everyday so I need to get it fixed or trade it in on a ram (and have my wife kill me) [emoji23]

I'm there with you, mine had the same problem and I spent a lot of time chasing it.  All the techs would say is "feels like a tire balance issue".  I will say that the lift definitely made the ride feel "tighter" if that makes sense, almost like the shocks are better, or whatever they did when modifying the truck ended up tightening up whatever was loose.

Sounds like there's a "fix" for the high speed shake... has anyone overcame the acceleration studder at 1200-1800 rpms?  Other than selling the truck?

The only reason I haven’t gotten rid of it now is because I’d lose about 4K trading it in, but at this point it might be worth it to not get driveline work done, new tires, and new shocks. I’m gonna see what this dealer has to do or say and go from there

You might try giving GM customer care a call and start a case with them.  Most likely they will get you a rental and throw parts at it until something fixes it or it doesn't get fixed, in which case they might do a buy back.  I had to do it once and I got to trade it in for what I paid.  Not quite a buy back, but at least I got out from it without any real financial hit.

Buy a programmer and program the converter for hyper mileage or economy. See my other posts for more info on riding smooth. I'm satisfied with my Silverado now but definitely will never buy a GM truck again. Corporate is not interested in customer satisfaction at all. If they are they can call me at 931-675-1161 and we will discuss. Bet all I hear is the wind!

Still looking for a used 2016-2017.  Is this vibration problem in every truck or is it just hit & miss?

I had a 2014 shaker that I traded for my 2018 that is smooth as glass. Best advice is get it on the highway and get it up to 70 to 80. But that doesn't guarantee that it won't develop later. Keeping my fingers crossed with my 2018. So far so good. Good luck to you.

      Lesson relearned on basic diagnostics...

      By calgator73 · Posted

      Coming back from towing a car to my daughter in Nashville truck started making a screaming noise from underneath.  Pulled over placed in park and sure enough whining noise from underneath.  Dropped at the dealer fearing new tranny or another front pump/cover replacement.  Service writer said it sounded like the tranny too...  Well $300, new idler and a belt all is good.  Pop the hood and give a listen. lol  Now I'm telling dealers I'm no longer interested in a new truck.

      OIL CONSUMPTION

      By newdude · Posted

      HD uses the 6.6 gas.   Oil consumption while heavy working is considered normal.  1 quart per 100 gallons of fuel is the normal rate above 8600lbs GVWR.  If more than that, it is considered excessive.   They will have to perform an oil consumption test using the guidelines in TSB 03-06-01-023J.     Information on Engine Oil Consumption Guidelines All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons, and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. Oil Consumption Oil usage has a direct relationship with the amount of fuel used. The harder an engine works, the more fuel and oil it will use. Therefore, oil usage as a factor of fuel usage is a more accurate indicator of acceptable oil consumption levels than vehicle mileage for vehicles at or above 8600 GVW. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is 1 liter (1 qt) within 400 liters (100 gallons) of fuel used. This rate only applies to vehicles under warranty, maintained in accordance with the appropriate maintenance schedule, driven at legal speeds and within design intent of the vehicle. Many factors can affect an owner's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil consumption. Gasket and External Leaks Inspect the oil pans, engine covers, and the engine oil cooler for leakage. Inspect for oil leakage into the engine coolant. Improper Reading of the Oil Level Indicator (Dipstick) The vehicle must be parked on a level surface to obtain accurate oil level readings. Verify that the dipstick tube is fully seated in the block. When checking the oil level, make sure the dipstick is wiped clean before taking an oil level reading and fully depress the dipstick until the shoulder bottoms out on the dipstick tube. The dipstick should be the proper part number for the engine/vehicle that is being checked. Not Waiting Long Enough After Running Engine to Check Oil Level The vehicle should be allowed to sit for at least 15 minutes, after the engine has been shut off, before taking an oil level reading to assure the oil has had enough time to drain back into the crankcase. In order to ensure accurate results, the temperature of the oil should be close to the same temperature as the last time the oil level was checked. Improper Oil Fill After an Oil Change Following an oil change, verify that the proper amount and type of oil was put in the engine and that the oil level on the dipstick is not above the full mark or below the add marks. Refer to the Owner's Manual or Service Manual for information on recommended oil quantity, viscosity, and quality. High Speed or High RPM Driving Continuous driving at high speeds/high RPMs may increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected. Towing or Heavy Usage Towing a trailer or hauling additional weight will increase oil consumption. Large frontal area trailers will further increase the work required from the engine, especially at highway speeds, and thus increases the rate of oil consumption. PTO Operation Operation of a PTO will increase fuel and oil usage, as the PTO driven accessory uses engine power to operate. Crankcase Ventilation System Verify that the positive crankcase ventilation (PCV) system is operating properly. Blockages, restrictions, or damage to the PCV system can result in increased oil use. Oil Dilution from Condensation On vehicles that are usually driven short distances, less than 8 km (5 mi), especially in colder weather, condensation generated from cold engine operation may not get hot enough to evaporate out of the oil. When this occurs, the dipstick may indicate that the oil level is over-full. Subsequent driving on a trip of sufficient length to enable normal engine operating temperature for 30 minutes or more, in order to vaporize excess moisture, may give the customer the impression of excessive oil consumption. Engine Temperature If an engine is run at overheated temperatures (see Owner's Manual or Service Manual) for more than brief periods, oil will oxidize at a faster than normal rate. In addition, gaskets may distort, piston rings may stick, and excessive wear may result. Verify that all cooling system components are in proper working order. Engine Wear Piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption. Measurement of Oil Consumption Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi).   Verify that the engine has no external leaks. Repair as necessary. Verify that the engine is at normal operating temperature (see Owner's Manual or Service Manual). Park the vehicle on a level surface. Wait at least 15 minutes, after the engine is shut off, before checking the oil level to make sure that most of the oil has had time to drain back into the crankcase. Check the oil level and record the vehicle mileage, date, and exact oil level on the form included in this bulletin. Next ensure the oil level is at, but not above, the full mark on the dipstick. add oil if necessary. Also ensure the proper viscosity and quality oil are being used as recommended in the Owner Manual Ask the customer once they have consumed 100 gallons of fuel schedule an appointment and return to the dealer for inspection. If the final evaluation shows that the engine uses more than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, follow the published symptom diagnostics as described in the appropriate Service Manual. If the oil consumption test shows that the engine uses less than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, explain to the customer that their engine meets the guidelines for oil consumption.

      OIL CONSUMPTION

      By RSTRICK · Posted

      I have a 2024 Chevy Silverado 2500 with the 6.2 liter engine, Vin: 2GC4YME79R1273849, with 27,437 miles. Recently we took a trip from Candor, NY to Townsend, TN pulling our fifth wheel, when I got close to the Townsend, TN area The truck gave me a message of low oil. I checked the dip stick and found it was 2 quarts low. Today, August 27, 2026, I had the oil changed and the technician Found the truck was very low on oil.  Is there a Recall for this? What is my recourse for this issue? Do I call the dealer where I bought it or any chevy dealer?   Robert Strickland 292 Owego Road Candor, NY 13743 352-502-6588 [email protected]

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      That is the funnel kit I bought and for being here in Canada I did get a better deal than what other sources were charging through a certain supplier in town that sources more directly and they ordered it for me. There are other items now on the market which would be perfect as well but this has worked well which was the hope when I bought it. I mentioned the Amsoil quart bottles as they have that squarish shape up top and it props nicely on the rim of the opening without falling into the funnel so I can leave them sit and drip a bit. You may have already figured out that to get the cap off the valve cover unless one is 7 + feet tall its not going to be reached without standing on a step of some sort and so when I do that I put the right adapter in and just leave the elbow on the funnel all the time anyway and open the lid and then if using quart containers for sure I can stand beside the truck and leisurely add the oil, and I can leave that funnel on when starting the engine to let it idle to fill the filter and then add the rest of the oil to top it up before removing the funnel and putting the factory cap back on. I put the cap back on the top and slide the bottom cap on as it fits onto the elbow adapter also and then store the funnel in a clean household plastic garbage bag along with the adapter so I have no reason to be washing out the inside of the funnel as I keep it completely clean between uses.    Draining the oil as per the under the truck portion, yes indeed that is slick as someone was thinking on GM's part there and admittedly I don't drop the oil screaming hot in this truck due to the exhaust being there and makes it safer as far as the oil temp if its just warmed up some instead as I don't have the truck on any ramps etc as I do it as the tires sit on the garage floor. The filter is not boiling hot then either and can drop it off into another pail after pulling the drain plug and just leave it drip out. Go back under a few hours later with new filter in hand and clean off the filter base and put the new filter on and install the drain plug. The filter is a little cramped in there as per wrapping ones hand around the filter and I am so used to using the band style filter removal tool that its no big deal and same for snugging it up. My filter wrench is many years old now but I think this is the current version and sounds like the right size, just in case my explanation was not great ( those nylon strap wrenches that one tool fits all filters are not my favorite tool to use, I much prefer this style personally )     57020 Swivel Gripper - No Slip Filter Wrench - Small | Lisle Corporation   And again about the oil draining and filter setup under these GM trucks, I've watched Ford videos of them struggling with oil flying sideways out of the oil pan on the gas 7.3 due to the sideways drain plug onto other components or cross members and guys trying to make shields out of carboard etc and other Ford pickups that Ford insisted they have sideways drain plugs. One win for GM there anyway with this engine.
