Shake or Vibration Issues

[Enforcer]

Hey Everybody, this may have been brought up but there is noway I'm going through 501 pages to look for it LOL. I have a 14 Silverado and have had a shake issue since new. I've always wanted to take it in but being a project manager for a busy construction company I never had the time or patience to deal with their stupid loaner car.

 

I guess my question is, at 77k miles is it to late to deal with this? I feel like it's now getting worse and am really regretting not taking it in earlier.

 

Anyway, thank you for the help in advance.

I really doubt they would do anything with that type of mileage, but I've been wrong before !

 

They are making plenty of money, so I figure the GM attitude is hope this all blows over.

After 6 months of "vibration frustration", including 20 tires and 16 wheels, the BBB arbitrator says tough luck. The system will flat wear a guy out. On my arbitration date, last Thursday, it was 36 degrees, raining, cab full of 5 large adults and a driver (arbitrator) that didn't want to drive over the speed limit. With these 4 factors, there was very little vibration. Today driving home from work with no rain, 45 degrees and sunny, and just me in the cab, driving 77 mph, it shakes like crazy! Go figure! It's time for me to just take my loss and unload my Silverado but I pledge to use social media to let everyone know to BEWARE. Now I'm thinking a pre 2014 GM truck, a Ford or a Dodge. I can't believe it has come to this.

Sorry to hear the outcome....Im still waiting for my arbitration decision from last week. Ive already begun looking at new trucks as Im anticipating trading this POS in. Researching other brands ive come across videos of the Ram and F150 with the same issue. Knowing my luck I will probably get another lemon. It seems like the Tundra is the way to go with the least amount of complaints. Good luck on your search and let us know what you end up with.

Everyone that has the vibration listen up. My 2014 Sierra was fixed by having the rear end rebuilt. It turned out that there are bad seals in the rear differential so they replaced it and the pinion and a gear. Running smooth now. Background: Steering wheel shook at 40-52 mph especially when coasting to a stop. They tried new tires and road force balancing but that did not work. One GM engineer even told my service manager that they could replace every part on the truck and it would still shake. Don't take that for an answer. Paying 40+K for a vehicle and having that shaking is not acceptable. BTW, mine did not start until 5K miles and got worse until about 15K. Now I hope it is fixed at 19K. Good luck and hope this helps.

OK it'd been a while since I last posted. With that did I do read these updated posted several times a day. So many different ideas on what the cause is. I have encountered something I haven't seen before. Over the holidays I drove to Massachusetts from Jersey. Still vibrated and I think has gotten worse very recently. One thing I noticed something odd on my trip back to Jersey. For a moment maybe several miles, maybe more then 5 less then 10. The truck drove like it was on glass. It was so noticeable that I was almost in tears, lol. Just a thought, I'll say what I was thinking. It was like whatever magic lottery ticket that I just cashed was something that phased in sync then phased back out. Almost as if from various turns, maybe from the limited slip which changes phasing of the timing of axles and rings pinion that it momentarily BALANCED!!!! When it happened I was on a rather straight portion of road and as it started to slowly curve the vibration came about slowly then progressed. This wasn't a momentary thing or a temporary road condition thing. So I figured I'd throw this out there maybe someone has a thought that would expand using what occurred. Thanks, H.

Your steering wheel shake at 40-52 mph sounds like a different issue that the vibrations at 75 mph. Of course, there could be multiple problems with these vehicles, each with a different (or non-existent) solution.

 

How does yours behave at 75 mph?

Drives smooth at 75. I was told the harmonic oscillation can occur at any speed. I would still have them check with there vibrational machine if the rear end is in spec at that speed. New tires and road force balancing did nothing for the vibration I was experiencing.

SteveU, did your dealer use a PICO on your truck? What did the dealer tell you was out of spec?

 

I did not review the readings but took the dealer's word that it was tires needing roadforce balanced.

 

Road Force balancing made and improvement but vibration is still there.

 

So my question to all again: Are some dealers hiding the real PICO readings? Hoping we go away? Or are the PICOs picking up tire when it should be rear end?

Yes they used a PICO on the truck and confirmed what I found to be the fix online. The vibration was coming from the gear and pinion in the rear differential.

Also, I think most dealers don't have a clue what is going on because they are getting bad advice from GM. One GM engineer even told the service manager that they could replace every part on the truck and it would not fix the problem. One engineer told the shop where I bought the truck it is caused by the engine switching from V8 to V4. Give me a break. I don't think they want to admit there is a big problem out there coming from the rear end but the instrument does not lie.

Update

GM Tech Support has determined the rear end needs replacing again.

The replacement parts the dealer installed a month ago were in spec but were made in Mexico so I guess they were not certified or something. The new parts on order are made in Michigan which means they are certified so they are guaranteed to work... supposedly.

I said the whole truck was made in Mexico so I guess that's whats wrong with it then. Send me one made in Michigan and maybe we'll have a certified truck.

Hey steveU, listen up. As soon as you start a post with "listen up" most people are going to tune you out lol

 

And glad your truck is fixed, hope it stays that way for you. Most who have had the rear replaced end up having the vibration come back.

If they replaced every part on the truck with the same crappy parts that are causing the problem, of course they will not fix anything. The solution is to overhaul the whole manufacturing process and start producing quality parts and assemblies built to proper tolerances. So now you see why there is no simple fix here.

I bought a Tundra after 3 sets of tires going to my 4th set on my 14 Silverado. I love it...... Especially since gas is less than 2 bucks. But even if it wasn't I'm loving not having issues or recalls with my truck. Had a Ram before I bought my Silverado and Transmission went out after 3000 miles. I dared not give Ford a chance. I'm happy for those owners with no issues....just not my experience. Good luck!
