How so? There is 5, 10, 30, 35 and 40oz weights, how do you come up with 2.25 oz?? He didnt specify what type he has on there. 3oz is excessive.

If you took time to look at the picture he posted you would see that they are 1/4 oz weights. 1/4oz x 9 = 2.25oz. Go look at your wheels and tires. Guarantee there is close to 3oz on each wheel.

Pic didn't show for me until it was open in Chrome. Could be more weight on that rim. Sure might have 3 oz which is excessive, I don't ever remember putting 3 oz on a wheel when I worked a t a dealership.

Truck still in the shop they put brand new Goodyear sra still didn't fix it. Now putting all new shocks

 

JC84, please let me know if the shocks work and if they are stock or if GM may think bad shocks are the issue.

Ok guys I have the same issue with my rally 2 with 4000 miles where do I start this sucks

Welcome to the forum Arun9lude,

 

Start by making an appointemnt at your dealer for your concerns, Check your states laws on Lemon Laws, Buy Backs

and the BBB site.

 

In most cases the dealer has four attempts to correct the issue. Keep track of your mileage The dealer/GM put over

a 1000 miles on mine and never corrected the vibration issue. also keep notes on dates and times along with the people

you talk to and their position, most of all be nice it really helped in my case.

 

Sadly, GM has been aware of this since 2013 and with the record sales they are having it is not in GM best interest

to solve this anytime soon as their record speaks for it's self.

I have a 2014 chevy silverado Z71 double cab with 21,000 miles on it and I have had a shake since I had 500 miles on it. My truck has been in the shop more times then I can count. Here recently the dealership has helped me big time. I had the service manager ride with me and he clearly stated that there is something wrong with the rear end. I would get up 75 to 83 mph and my center console would shake really bad. They took my truck in and 2 days later gave me a call and stated that the ring gear wasnt straight it was reading 0.03 but should be 0.02. I have had my truck on the road after the shop visit and it's riding nice and smooth so far. I have goodyear tires on it and I'm going to have those changed very soon, the dealership has road forced them 7 times. Everything is factory with my truck and I have been dealing with the shake for over a year and finally got something done about it.

Of the two new tires my dealer put on, I did notice one of the other ones they left had a LOT of weight on it.... I too like my truck but agree with others that the quality has gone down... I've still got some vibration, rear end "Clunk" sometimes, then there is the "Ching" sound when I apply the gas easily after letting it coast. All these issues are on this forum so I'm not alone...

Ok my ride has been in the shop since last week with the vibration. They road force balanced the tires, with no resolution. They are looking at the rear end now. They need to decide a course of action with the service manager tomorrow. Guess I'm the first at this dealer with this problem. The video I took was eye opening to the tech last Friday.

There stock shocks.

He told me gm said when they replace the tire they replace the shocks as a precaution. There hoping this fixes it which I doubt it. will find out tomorrow hopefully when the shipment comes in with the shocks.. I still think it's driveshaft or rearend related.

Still dealing with this issue, It will be a lemon law case by the end of the week without any results, I have 3 new goodyears and a new ring and pinion. still will shake you out of the passenger seat.

Okay, so I am at my local GMC dealership for service (oil change). I ask the customer service rep if they have had any Sierra's come in with shake/vibration issues. The answer was yes, and I asked if they fixed the issue. I have to add that these guys know me, and they know not to BS me. I was told they fixed the issue by loosening the body mounts, drove down a few rough roads, and re-torqued. Supposedly that fixed it. I was also told that the pico meter was giving them the run around and they had tried pretty much everything else.

 

So what do you think?

It surely is possible, I know the Jeep trackbar had to be torqued only at ride height and not on jackstands. If it truly is the fix, I will be loosening the body mounts tonight

Here is an update to my previous post. When dealing with the shake/vibration issue, they must go through the list prescribed to them by GM. If there are aftermarket drivetrain components on the vehicle they must rule them out before proceeding through the list. The body mount fix was a last ditch effort by them just to see what would happen, and I have been told it worked on more than one occasion. The pico meter measurements taken after the fix were actually better than the measurements on a vehicle that never had the issue in the first place.

 

With that being said, they have to go through the process eventually reducing vibration/shake to a level that is not noticeable. So it seems to me there is not a "magic" one item fix, but maybe a combination of fixes.

I have had an issue with my truck that I thought was my wheel spacers, but turns out its still there after. At abour 45-70mph on smooth roads I get a hobble. Its not a shake side to side its a shake up and down, makes it feel like I'm on a wavy with bumps in it. Not sure what else to do, my wheels were roadforce balanced just recently, but it is possible they didn't do a great job.

    • Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.
    • Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.     
    • Thank you. I'll give it a try 
    • I just spent the last 45K miles doing samples every oil change over more than a full year to get the data for seasons and break-in to broke in.    I found the same thing to be true. Something was always teetering on done or had stepped off the cliff long before the OLM was DOA. In fact, I found about a thousand mile difference between summer and winter. That is during the winter half the OLM was STILL too long. Even the severe schedule was to long in the winter.   Now having done the work I can say I was NOT DISAPOINTED. I saw nothing I didn't already know. Nothing my father hadn't already demonstrated in his 2K OCI's pushing dated iron on dated oils and weak filters to mileages well beyond 300K.   Building on his work through use of Lab testing it wasn't hard to find the correlation between 'sight/feel/odor, the things dad relied on, and test results. Use of current viscosity stable chemistries & filters has pushed that marker for my motors out to 3K summer, 4K winter.    So the early lies were 3K on conventional oil and the lie upon the lie was 7K+. turns out to be off by a factor of two.    So... it is true that modern chemistry has doubled the useful oil life. But the base milage that came from was off by double. It's how good lies work. Partly true, sometimes mostly true so that your meter isn't set off. It also means that non-shear-stable shelf oils are only now as good as the old oils were in their best case scenario.    So the question now is how do we improve on that? Thus the question into cleanliness among the other items listed in the post quoted below.    If this bores you, feel free not to participate.       
    • Is it though?  Like LTZ, not a high take rate.  Current Sierra has AT4, Denali and Elevation as its main bread winners.  Each trim accounting for 25-35% of sales for Sierra.  SLT makes up about 10-15% at best.        Like others have predicted here for GMC, it will be:   - Pro (equal to WT Chevy)   - Elevation (replaces SLE and SLT)   - AT4 (and X)   - Denali (and Ultimate).
