My truck would vibrate over 80mph. Not bad at all but I could feel it and my buddy would always ask if I had a bad tire. It was a 2016 silverado. Dealer never found the issue either but did admit of the vibration.

Does anyone know or heard of GM setting a Max Tire Weight for the 1500's suspension?

I picked my truck up from the dealer yesterday after dropping it off on 5/16/17.

As I stated before the first thing they did was put factory tires on. I purchased new Nitto Grappler G2 275/70/18 the week before because they wouldn't do the testing with the "mud" tires on. (Duratracs). After the factory tires were on they ran pico test to find the vibration. First they replaced the drive shaft, no change, then they changed the ring gear and pinion which they say has solved the problem. Seems better to me but I will put it to the real test on a longer trip next weekend.

After they admitted the tires were not the cause of the vibration and I got my truck back I have asked GM for reimbursement on the tires I bought since I think they wore prematurely because of the truck vibration. As with any GM situation I get 1000's of questions regarding the maintenance of my tires. Balancing, rotation, air pressure, weight of tires, size of tires etc. The service manager claimed GM 1500 suspensions are only rated to handle 37 lbs per tire, the butter cutters they use (SRA) are 36lbs. This is why I asked the question above. Service Manager: "It has never been my experience a ring gear and pinion issue would cause tires wear, a vibration in the chassis yes but never tire wear. Tire wear has always been related to shocks, alignments, under inflation, over inflation wrong or too large a tire for the application."

 

Regardless of the technicalities I feel like $700 for tires is a fair amount considering all the trips I had to make to the dealership(s) to get this issue fixed when it should have been fixed the first couple of times I brought it in.

I took a 500 mile trip on an interstate road last weekend and the shaking was very evident at 70 mph and above. Feels to me like it comes from the rear so I lowered the driver's side mirror to look at the wheel. I can clearly see it wobbling ever so slightly to the exact frequency of my vibration. Passenger side is fine. So I swapped the tire for my spare. Same wobble still there. When I got home I removed the caliper and disc to see if the disc was seated on the axle flange properly which it was. The axle flange itself is not true.

 

I have an appt at the dealer friday. What are the odds that they'll even check the axle flange runout even if I tell them about it. My bet is they balance the tires yet again and send me on my way.

You're not the first to note poorly manufactured axel flanges, but it is important to note that this is not something that GM checks, to my knowledge. Those who have found this issue, found it themselves. I have a dial indicator and have been meaning to check mine as well...

A new axle shaft costs around $350 and probably that much for labor to install. If GM won't change it, I may just have it done elsewhere. I'm just so tired of this issue and it's simply a damn shame to have this problem on a new truck. GM is losing all respect from me and I'm telling everyone I know.

Just got home from the dealer and as predicted, they don't find anything wrong with it.

 

Has anyone heard of maybe the brake disc itself having a defect that would cause it to be uneven? I guess a dial indicator would really help here. I may have to borrow or buy one.

F-series, and Ram sales up for May 2017, GM Silverado and Sierra sales continue to drop! Word must be continuing to spread about their vibration problem that can’t be fixed. Either that or people are learning that the Silverado and Sierra don’t have the following features that are available on the Ford F-series:

  •  

  • Blind Spot Monitors
  • Adaptive cruise control
  • Rear HVAC vents
  • Keyless ignition
  • DOHC, 4 valve/cylinder engines
Guy I work with has all that on his F-150! It also shredded a belt at 50 some thousand miles and had to have it towed? No thanks he will be onto his 3rd F-150 by the time I dump my GMC at 200K+ and it probably will not give me any troubles to 200?

Bad radio reception and Sierra's have candles for headlights.Dealer said they don't want these used trucks.Of course they will steal them from you on trade in which is pretty much normal.

Those of you who've experienced axle problems will like the below info I extracted from another thread on this forum. Maybe there is hope :)

 

"GM will build axles for its next-generation full-size pickups at its Grand Rapids components plant in Wyoming, Michigan, a move that is tied to investment and jobs that the automaker announced more than 18 months ago, according to two sources familiar with the automaker’s plans.

 

The automaker on Tuesday said the move to operations in Michigan would create 450 U.S. jobs. A GM spokeswoman declined to name the supplier or where or when those jobs would come to the U.S. However, American Axle & Manufacturing Holdings Inc. confirmed Tuesday that it was losing the work."

Well I have been quiet about my truck mainly due to being in the buyback process and not wanting to jeopardize the process.

 

Now that it is complete I can give the Steps that were taken.

 

Truck had 6 sets of tires put on it

One new set of wheels

New axle shafts

New ring and pinion

New steering rack bushings

New front hubs

 

All of this did not correct the issue, matter of fact the hotter it got outside the more the truck would shake, leading me to think it was transmission related.

 

I will say your first line of defense and advocacy is the service manager or in GM terms the Customer Experience Manager (CEM). He/She will speak on your behalf to the DMA who is the district rep.

 

In my case my CEM was great to deal with and I treated him with the utmost respect. If you encounter a CEM that is not helpful go somewhere else. Do not be demanding and let them run their process.

 

In my case I was in a rental for 52 days.

 

Hopefully this helps with you all who are experiencing this issue.

 

Just remember you can get more bees with honey.

This what we ALL need to do. Just tell as much people as we can, have to get that word out. It is getting out as shown by Gms terrible truck sales recently.

If all of the replaced items were not broken or defective and were replaced with the same part to figure out a problem, then yes, the issue will be unchanged. If the part was upgraded in some way, then it makes sense. GM was throwing crap on the wall to see what stuck until it just wore you out or you got lucky enough to get out of the deal. Both in your case

    • I'd change the fluid and start there.   198F is nothing for the 8L90.  They typically operate 180-200F stock.  
    • Looking for help!   2019 GMC Sierra 1500 - 5.3l 4x4 8l90 61k miles - truck is in Arizona, was over 110 outside on Monday when this whole situation transpired. Never had any major issues with transmission until this point:   Truck sat outside my construction office for approx 1 hour idling before I realized, ran around the job site wrapping some things up for the day and then left. Went to get food and sat in the drive through for approx 30 minutes idling. As soon as I pull out of the drive through and onto the main road, rear tires lock up and feels like transmission fell out of the truck. Shifted to park, shut the truck off and tried again, same thing happened. Was able to reverse into parking lot (truck slammed into reverse). Let the truck sit turned off for 10 minutes before trying again, but it continued to happen. Towed truck back to my house. Highest the trans temps reached was 198.   Friday, after work I start looking into the situation. Truck sat in my driveway untouched all week. Truck is now driving like normal, transmission doesn’t get over 185 degrees when trying to heat it up. Got up to 60 multiples times with no issues, no issues accelerating, only down shifted hard into first one time at 185 degrees. Does anyone have any insight? Never through a code or a check engine light. Truck has never been used to tow either. No transmission services at this point.
    • Atlas won.   I know better, but I did it anyway. I took a compressed air line with a chuck and rubber tip and jammed it in the open EGR port. The port was clear as far as I could see, and as far as I could poke with a flexible wire, but that doesn't mean it's not clogged.   Compressed air blew back at me along with a cloud of black. Oops. I didn't have the rubber tip seated in there all the way. Jammed it up in there some more and squeezed the chuck. PSI was set to 120. Poof! It blew back at me again. Third time...pfffffttssssssspffffffsssfffffff, face full of carbon, and then, kind of a thud..and the air stopped spraying back at me. It was now exiting the exhaust with a low shhhhhh sound as it flowed through the pipe. Something broke free. I pressurized the port again, and air flowed.   Made my day.   Long story short on this problem, it's fixed. Something was really blocking the EGR passages down low, and compressed air blew it apart. I don't recommend this as who knows what debris was sent where. But it's allowed me to move forward, mentally, and onto the next problems I need to get this little S-Blazer going down the road properly again.  
    • Your truck lowered, looks good. I'm happy with the stance on this. I may need the extra ground clearance given my location/situation.
