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

I know 3 is a small sample size but what, if any, differences are there in configuration of the three ? All Z71 ? Or all CC ? All 4x4 ?

All crew cabs. The 14 is a 2wd chevy LT. The 2 15's are both GMC crewcab 4x4 SLT. mine is a z71 my buddys is a max tow with the 9.76 rear end.

Another update: I got my truck back this past Thursday. When the driver dropped it off he told me he had it up to 85mph and it was smooth.

I THINK ITS FIXED!!! I waited until today to post as I wanted to drive it several times. The dealer replaced my ring and pinion {rear end} and then put on new tires and wheels. I drove it several times on the interstate, max speed of 83mph and it was smooth. My 14 year old said "wow this is what is should feel like. Very excited right now and hope it doesn't return. Only issue now is they put black wall tires on and I like white letter. They are going to correct it this week.

I don't want to publish the name on my dealer on here but if anyone else's dealer is unable to fix their truck I will be glad to give you the name of my dealer and the service managers name so your dealer can, if they wish too, contact them. Want to help others hopefully get their trucks fixed. If I can be of any assistance please let me know.

 

A full rear axle replacement [brake rotor to brake rotor] eliminated the vibrations in my Yukon as well. Mine were not nearly as bad as some of the videos I have seen in this thread.

 

My dealership also replaced several tires and getting them to RF balance under 15lbs eliminated the 'buffeting' that many of us have reported in the Yukon/Tahoe/Suburban thread.

 

The last noise was the "booming" that could be heard when driving over bumps and snow/gravel covered roads. This was resolved by welding 6 dampers to the exhaust.

 

Nice to see another one get fixed.

Glad to hear yours is fixed as well. Mine was fixed with the ring and pinion and new tires all the way around at 25000 miles. I just turned over 40,500 yesterday.

I test drove a 2016 today and it had a noticeable vibration at any speed above 40mph. The odometer had 4 miles on it and it's build date was in February, so I'm hoping it's just from flat spots or out of balance tires from sitting so long. I asked if they could rebalance them or swap the tires with another truck on the lot, and I will re-test drive. We'll see what they do. The 8-speed shifted fine though from any speed or gear.

It's not the tires. this has been mentioned many times on this forum. Try another truck instead?

In my case it was the tires, unless other parts start losing their tolerances and the truck starts to vibrate again

You are one of the lucky ones then. In my case, and many other postings on here many also concluded it was not the tires. In my case, they replaced all four tires. It still vibrated. Then they Road forced and had to replace one of the new ones they just installed. Yes, when they replaced and RFB's the tires, the vibration was better, but it time, the vibration came back. I still have a vibrator. Been a GM guy all me life, but I think I may need to bend over and get a Ford. I cringe when I say this!

GM seems to be dragging their feet with getting me the updated trade assist letter.... last week i git an email saying they would get in out in the next couple days. its now over a week later and still no letter. they have been using fedex 2 day, so I don't know whats going on.... getting really annoyed and thinking they may be playing games until I can no longer file lemon law

The Chevy dealers are not charging for all the time and work spent in the shop, correct? What if you purchase the truck used and the issue shows up? Is it still under warranty to where they will still try all the above mentioned troubleshooting?

I would say run and try another brand instead. To me, this game of finding a truck that does not vibrate and hoping that the vibration does not start around 2500 miles, would be acceptable if they were giving them away free.

I had question for you guys. I was watching YouTube on the vibration issue and I'm sure you know there are tons of videos. I came across this one. Seems like just another of many "who thought this design was good" engineering. I drive usually 20 min a day on the highway and don't seem to have a severe vibration like some. I drove from Mass to Fl and back (3k miles) and was fully aware it vibs. I do have it though at the same speeds as everyone else and a resonance, low hum I guess, associated with it. My friend has a bone stock Silverado that he said shook severely and had the tires rfb and that fixed it. I've already tried the clamps on the rear springs which may be hookus pookus but seems to have slightly helped but gonna try my hand at the rfb.

My question..has anyone seen this or tried this and able comment on it...video below

Something all should look at is the transfer case. On mine sitting and idling it has quite a bit of shake. With the transfer case hanging off the transmission with no brackets attaching it, could this be our vibration issue? The case has spots for mounting brackets but nothing's attached. Just an observation I've seen on my truck. I have the E brake cables rubbing on the body mounts and they are cut pretty good with 8000 miles on truck. My rear end is noises as well. I just completed a tire rotation and my truck is actually 10x worse than it was before.

Well add me to the list I guess. Just bought a 16 crewcab Z71 LT on Friday and had vibes on the highway on the drive home. Brought it back next day, they did RFB and tire rotation. Didn't help much.

 

So picked it up today, after 3 hours in the shop. Was told it drives 100 times better now. I asked what the problem was, turns out that 3 of the tires were about 5 psi too high. That's actually what they told me. That the over inflation "made me feel every bump in the road" and that the Z71 package is stiffer. I guess the Z71 also has the drink mixing feature as well.

 

At any rate I am going to get documentation of the first two visits and take the tech out for a ride tomorrow. Wish me luck.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
