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

My '16 Z71 has vibrated since day one at around 45 mph and then again at about 75 mph and up. Little over 2,500 miles on it at present. I have dealer appointment no. 3 set for Wed. 12/14. Thing is, the vibration is hardly there at all for the past week or so. Only reason I can think of is the cold temps here in central NY?? Same thing happened a few weeks ago when we had a little cold snap.

 

I'm thinking of canceling my 12/14 visit to the dealer and waiting for warmer weather, as I have no doubt the vibrations will be back....not sure what to do now. To me, there's no sense in taking it in if the vibes aren't there. What do you guys think...delayed visit make sense??

If it's not shaking in the cold which is the same way mine behaves, You will get the operating normal or within spec and sent on your way without them doing anything.

Yep... That's what I was thinking would happen.

How would I check that? My dad and I rotated both rear tires while on the truck and they were spinning true. We put a dial gauge on the edge of both tires and had zero readings on the gauge. They were spinning true. I would think if it was the axle flange then my tire wouldn't be spinning true and the dial indicator would show a reading.

Watch the video post 10114 look at the outer edge of the axle.

So, called dealership today to check status. Got told I would have to pay $150 for a picoscope. A visit and a hell raising changed that. Told them give me my fking pickup and I'll take it down the road to the Ford stealership... that changed their tune. Now they're going to do picoscope for free (surprise surprise) and should let me know the results tomorrow. Not very optimistic. Left in the loaner and immediately went to the Ford shop, no Raptors in stock unfortunately, because that's about the only thing I'll trade out for. They're trying to blame my vibration on the one time I got stuck in the mud and needed a tug to get out "tweaked something" is what they keep claiming.

If a 2015 4WD can't take a tug without something going wonky, then it's a piece of shit. Ive been tugging 4wd pickups for years, don't give me that line.

Cold weather seemed to minimize my vibration as well... something in the metallurgy of the rear end components perhaps?

Yes, people's rear ends tend to get stiffer in cold wether, so they will not be as sensitive to vibration. :crackup:

What I see is that there are a few parts that dealers and owners are replacing.

Tires

Differentials

Wheel bearings

Axles

I think I seen a torque converter or 2

 

But I think there are more parts that could be causing it.

 

A change in body mount material?

 

Too hard or too soft?

 

Engine or transmission mounts?

 

Leaf springs?

 

My vibration/shake feels like its side to side.

I've changed: wheel bearings & Tires

No change. I'm fixing to start swapping parts from 2013 or down trucks to see if anything changes.

 

Going to swap wheels, then leaf spring as long as they are the same.

 

Maybe even the front struts since they seem interchangeable. Cause it might be a change in spring rate.

 

What do you all think? Some of the guys here are mechanically savvy. What things have you tried or thought of trying to fix it. Going to the dealer isn't an option since I'm lifted and get the "it's your fault".

Yes on the tourqe converter

Drive shaft

Deferential shims/ ring and pinion if I remember correctly

Some people have a done a clamp mod on the leafs spring and stated it helped out or solved the issue

I find it interesting that some of you are reporting that cold weather lessens or takes the shake away.

I think this w could be explained if tires are actually causing the vibration. If you happen to have a tire on your truck with a loose steel belt, it will vibrate more the hotter it gets, so cold wether actually helps reduce the vibration caused by such defects.

 

I did have such a tire on my Mazda 626 years ago and the vibration was less in colder weather.

Here is some info from another website, don't remember which as this was in a text file I had.

 

 

Most people have trouble determining if the vibration in their vehicle is coming from the DRIVESHAFT or not. There are typically two types of vibration most vehicles would have. A fast cycle vibration or a slow cycle vibration, to help understand this lets say we put a bucket of water on the passenger’s floor. If the vibration in the vehicle produces small ripples on the top of the water this would be considered a fast cycle vibration. This type of vibration is usually a drive train vibration, things like the driveshaft, motor or torque converter. If the vibration puts waves on the top of the water or splashes, this type of vibration is a slow cycle vibration and usually is an axle or tire vibration. People have trouble determining where the vibration in their vehicle is coming from. Try the test below if your not sure.

A simple way to do this is put the vehicle in question up on jack stands, block the front tires and run the vehicle up to the speed you have the vibration. Make sure you use the brake to stop the drive train before you put the car in park if it’s an automatic. If the vibration is a fast cycle vibration you may want to have the DRIVESHAFT checked for balance. This may make no sense to you but you may try indexing the shaft 180 degrees (just pull the shaft off the rear yoke and put it on the opposite way). What this does is change the resonant frequency property of the driveline and in many cases it takes the vibration away. If you have a slow cycle vibration take the tires off the car (make sure you put lugs back on the axle to keep the brake in line) and run the vehicle again. If the vibration is gone you now have to find out if it’s the rim or the tire and good tire shop can help you with that.

Has anyone worked or looked at the emergency brake? It may be too tight and in warmer weather it may expand, a slightly touching e brake will make you wiggle like a bad tire.

 

 

Just because the light is not on does not mean it isn't. Slack, tension in the cable can cause the light to go off but not necessarily full release on the ebrake shoes.

 

Just a thought

The items most affected by temperature swings are all the rubber parts. Tires and pressure, body mounts and fluid inside, and all the suspension bushings, oil viscocities, not only does it seem like the shaking is minimal when it's cold but the truck seems to ride better in general. It's like the rubber is too soft in the heat. Metallurgy is also affected by temperature but small swings are typically neglected for stress and deflection calculations of steel, It would however affect the K value which can contribute to resonance, All of this still doesn't explain why only some trucks have this issue unless all of the trucks are on the edge and only some happen to have all the pieces fall into place to create a vibrator.

      New to Me 2010 SLE (Quirks, Issues)

      By fm2176 · Posted

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      By fm2176 · Posted

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.

      Multigate electrical problem

      There was a recall on the tailgate in general for opening on its own. Mine has a cap on it and it won’t let the tailgate open.   My tailgate has two holes in the top of the tailgate. I filled them in with silicone sealant.
