Balancing the tires got rid of 80% or so of my vibes but still have some. I believe in my case it is a combo of out of round rims combined with crappy tires.

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

Got mine back last week from 3rd visit (second dealer). Tech did the PICO and determined it's "in spec". He can't do any work that GM wont refund him for. He admits there's a vibration but blamed it on the cheap stock SRA's.

 

I'm gonna keep playing with the clamp location and maybe try some different tire pressures to see what combo I can live with.

I've had this exact same conversation with my dealer. $4k later I've got the vibration down to a minimum. The problem is once you feel it and know what to look for it's all you can focus on no matter how small.

FINALLY AFTER A YEAR OF FIGHTING AND TWO TRUCKS GM IS REPURCHASING OUR SIERRA!!!! This has been a long crazy road and we are finally free! For those of you who haven't seen our story - we had a 2014 Silverado rally 2 that shook violently. We agreed on a replacement vehicle and picked up our 2015 Sierra on September 1st. About 1000 miles in it started to exhibit the same vibration. After waiting and waiting we finally received our response. GM will be buying back our truck!!! WE'RE FREEEEEEEEEEEE!!!!!!

My truck was a sluggish vibrating mess. On the advise of my dealer and unofficially GM tech support, I did a Diablo tune. Disabled afm, 87 octane with firm shift. Truck so far is working great. No vibration and I now love driving it.

 

There is no one source for vibration in these trucks. The factory ECM/TCM programming was the source of mine.

I'm very happy for you. It is nice to see that some people are properly treated when they have this issue.

Abominable, were you the person that was going to look for someone to balance the wheel on the truck so that hub and rotor were factored in?

If so, what were your results?

I have a steering wheel shimmy.

 

Last question for the crew, will a worn shock or one that loses its ability to dampen cause a tire to have excessive bounce. I think the answer is yes but:

Would it feel like an out of balance tire even though it might just be road undulations?

 

Coil springs on the front will pick up a natural resonance, some springs actually have weights attached to break up the resonance. If my shocks are worn (36000 miles but not leaking), it may not be able to stop the spring resonance by applying the forces against the spring.

 

I have a stretch of road in town that has manhole covers placed in the section where my right tire hits them.

It feels like the front end stutters over everyone.

 

I drive the exact same stretch of highway daily and to be honest some days are completely different than others with the handling

Properly treated In the very end but the process was a long hard fight. GM sadly tries to use ANY argument they can so that you lose. It's sad that I had to bring my 6 year old and 1 month old at the time just to show the arbitratior we're people and not another case. It's sad that we had to wait over a month for our decision on the case. Luckily, he saw through everything and ruled fairly!

 

 

Sorry I realized I posted with the wrong name earlier, this is the username that I posted all my experiences with :)

Im lifted so my u-blots were crushed on as tight as possible.

 

Just wanted to check in and see if the clamps are still keeping the vibes at bay. I stripped one of the clamps taking it off, so ordered another set and am going to put them on the rear like you have. I previously had them in front of the axle with not much luck.

I see on this forum some of our members are finding CV joints in the front with too much play. Will that cause a front steering wheel vibration?

These CV joints apparently meet the Chinese quality spec.

Well the dealer threw a bunch of parts at my truck and they said its ready for pick up. LOL

 

It was GM final attempt to fix this truck. Like the 6 times or so I took it in and they told me it was ready.

 

Lets see tomorrow when I pick it up and take it for a test drive. I'll report back.

      Towing In Loose Gravel

      By Z45 · Posted

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.
