Pinion angle shown in the simplest of terms. Shims can fix this.

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

Talked again with the service manager. Ring and pinion should be in at the end of the week. I will report back on how it went.

 

After reading some of the most recent comments, I wanted to add what he had learned from GM field engineer. They think that and have also had some tolerance issues with the teeth. Some are measuring zero clearance and some will be at 5,000ths. He said that under load/pressure you could get a vibration because you are going back and forth between clearance and no clearance. Also, the gears warm up while driving and of course when pushing more wind, towing, etc... Could make sense why my truck would vibrate more on a 45 degree crosswind. Again, hope this fixes it. I will report back. He promised me he would let me know what the measurement was of my old gears. Again, build date of 12/13 in Mexico. 5.3l Crew All Terrain.

 

FYI- The field manager said they have replaced 6 sets of ring and pinions in his area. How big that area is; I don't know...

Good luck. My money is still on the use of shims.....

So I have decided to post my ongoing vibration issues to the forum, as it appears I am not alone in this journey.

 

About three weeks ago, I purchased a 2014 Crew Cab, 2WD V6 Silverado with a 6.5ft bed. Recently (as in last week) I noticed a vibration resonating throughout the truck when I reached 30mph, and when maintaining speed, the vibration remained as well. I decided to bring the truck in to Chevrolet, and after a test drive with a service tech, he acknowledged the issue. After leaving the vehicle at the dealership, the issue was diagnosed as a bad drive shaft from the factory, and therefore covered under warranty. I was provided a complimentary loaner vehicle while we waited the four days for the drive shaft to arrive from Michigan (I am in Florida). Yesterday, I received a phone call from the dealership informing me the new drive shaft had been installed, however the issue was not resolved, and in the words of the tech, "it might be a little worse." He then informed me, they were now unsure of the source of the problem, and they were "attempting to figure it out." No progress update today, and no prediction of a timeline for resolution.

 

I have researched the Lemon Law procedures for FL, and I now must wait 7 days before formally notifying the manufacturer of the issue (the vehicle must be "out of service" for 15 days, OR Chevrolet must have made 3 separate attempts to fix the issue).

 

It goes without saying, I am extremely frustrated that this is happening with a brand new vehicle. And additionally the lack of a priority I feel the dealer has placed on resolving it, has not done much to ease my frustration. Hopefully good news comes soon!

 

I will keep you all posted on the progress.

I am also in Florida. Mine is in for the 4th time now and a total of 17 days out of service. I'm waiting for a new drive shaft to come in next week which they are telling me should fix my truck. I've got a CC with the shorter bed. I hope the driveshaft fixes my vibration but after reading your post who knows. I love the truck but hate driving it on the highway. Let us know what your dealer comes up with next.

From the "interesting or what" dept. 2015 Silveado double cabs have a new part number for frame vs 2014.

Returned my 2014 Silverado Double Cab LT 4X4 back to the service department with less than 300 miles on because of shaking and vibration. They got rid of most of the problem by road force balancing and replacing two tires. I still get a vibration between 45 and 50 and again on the highway at 70 plus. My question because I don't think I read it any where on the forum, has anyone had a problem with the power steering control module feature they call Smooth Road Shake Compensation? It's controlled by software and sensors which are suppose to help reduce steering wheel vibration. Maybe it could be sensors or even software not doing the job it's suppose to do.

I posted a link to an article that mentioned that equipment a few days ago.

 

I am going to mention it to service department next week.

M1Tanker, Sorry I must have over looked your post. I feel that the software or sensors could be be too sensitive. I get a loose feel when I drive over a rough road that's what got me thinking about this Smooth Road Shake Compensation feature.

I think that only shields the driver from steering wheel vibration, although I could be wrong. Most people seem to feel it in the body of the truck...floor, seats, etc. I'm betting if the culprit where one item, GM would have a fix by now. I think there are many different items working together to cause these trucks to ride terribly. Junk tires, electric steering, new (defective) body mounts, too stiff shocks, frame issues, poor drive shafts, vibrating exhaust...it's like GM has never built a truck before. Aside from No Starts, poor ride quality is the number one characteristic to avoid in a new vehicle and this has GM stumped? Come on GM. If they're not going to care about us...go out of business already.

Update.. Picked up the truck yesterday, road force balanced the wheels/tires again. It helped a bit but the shaking in the seats and steering wheel is still there. Decided to throw on my aftermarket 20s and toyo open country at2s on when I got home. This setup was on my old 2012 sierra which rode nice and smooth. Still shakes.

 

So I've pretty much ruled out wheels and tires. They better take a look at the driveline next. This is really starting to make me mad.

After road force balancing the tires on your truck, what does GM think the numbers should be? I've read where the Hunter machines used to balance your tires at some dealers are made just for GM problems they have. Of course the tech has to have the training and time to spend as dealers are always pushing.

They told me they aim for under 24. My dealer replaces anything higher than that with a new tire, although I think they first try to spin the tire on the rim to get a lower value. Right now I have, or had 2 tires that were at 2, one at 12 and one at around 8 I think? It drove better but still has a shimmey.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      By SteveP45 · Posted

      Idler Pulley… from what I understand GM and Chevy trucks no longer have an idler pulley.. they stretch belts for both belts… I had mine replaced by my local mechanic last year on my Chevy Silverado 5.3 z71 LT.   They have discontinued using them on 2019 through 2026 as of a Google search.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      By Fatboy2V-rod · Posted

      Good morning! I have a whirring sound coming from the engine or transmission area when driving w/o towing when I accelerate at 1100 rpm’s. That’s how it started. Yesterday it was more obvious while towing a U-Haul even when not accelerating at 70 mph. I could see where it may have been possibly shifting gears due to a slight grade and the intermittent rpm changes as the transmission was possibly lowering the gear down. It was making the sound multiple times but it is not constant. I replaced the serpentine belt and idler pulley but no change. It only does it when I’m driving. No noise accelerating while in park. Just started @ 53,000 miles. It’s not always there though. Unfortunately, I feel it may be transmission related. Any thoughts or knowledge about the 2022 tranny that anyone can share. I have 2500 miles left on my p-train warranty. Thanks to all for any help!

      RAIN. It's dumping buckets. We needed it. What a welcome change...sitting here listening to it pour with my office window open.   Ok, not too much. It's not even September yet, we're not finished with summer yet....

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      If you have actually done it, there must be some secret tool or method of accessing the hidden bolt head that both manifold connections have. Two of the three bolt heads are staring at you in the face from below but the third one is covered by shielding and as far as I know only accessed by removing part of the fender well lining to gain access to it and even then its awful to access or from what I had seen of someone fighting with it on a video.    There is a reason why even mechanics that deal with the awkward or risky business of undoing the exhaust at the manifolds have done the same method others are doing with these L8T by flexing the exhaust if need be or just able to slip the pan out as I did without needing to touch hardware or pry on the exhaust. By rights the two seals should be replace when those joints are cracked loose as well.

      Actually it was a lot more controlled then I thought it might be and that isn't actually when I spilled some oil. I had thought prior of rounding up a couple of longer bolts with the same thread to swap out for a couple of the front edge pan bolts and then leaving one bolt left in the back but loosened off and then using a suction device to remove most of the fluid, that certainly would have worked and while I do have a couple of different devices I could have used to suck the fluid, now having done the job once I wouldn't even bother. I had thought of buying one of those pressurized vessels to suck or new fluid in and would if I was doing a job like this on a few vehicles but with one vehicle I just didn't bother and I have pail pumps as well I could have used assuming the hose end would fit into that less than roomy space but being such a thin fluid it pumped well with a quart type pump and just kept the hose into the trans and kept swapping containers and repeat.    What I would change to the method I did though was first jack up just the rear of the truck to put on jack stands to allow more oil to come out of the check plug on the front of the pan ( and as I did, I made sure to put that drain plug back in finger tight ) then follow through by putting the front on jack stands. Also that I would have used a larger sized drain pan in the sense of covering an area wider/longer beyond the transmission but I didn't have one and saw someone else on a youtube video using a masonry mud mixing tub and bought one at a hardware store to use in the future. The main oopsy  I did and why I spilled some oil was all my fault as I neglected to follow my own plan, I should have let down the pan as I did to drain out the front of it as much as would come out but then scooped out the remainder of the oil with the Dixie cup I had sitting there just for that purpose as by that point there is enough room to reach right into the front of the pan and just bail it out basically.
