Shake or Vibration Issues

[abominable z71]

 

Just out of curiousity, what is the u joint bolt torque specs?

They don't have an exact torque spec but more of a procedure. This is from my memory but you can find it somewhere on this site. I believe you torque them to 59 ft-lbs. After they are all at 59 ft-lbs you then turn each nut an additional 130 degrees. not sure if this is the exact procedure but it's something along these lines. I have mine at 78 ft-lbs and from where they were from the factory to 78 it took almost 3 full turns to get them there. It helps but didn't solve the issue by any means.

 

I just re-read your post, you're looking for the u-joint bolts on the drive line? Can you even get a torque wrench on them?

I had a tech ride with me. He thinks it's the tires still. They are taking it to the Cadillac dealership on Thursday because they have a PECO meter and road force balancer. The saga continues

Any of you have 275/60R20 tires or larger? If so, what brand? Improvements to ride quality? I've been all over this forum and a couple others. Mostly curious.

I have that size in an LT tire. My vibration went away after swapping from junk stock tires, and these ride a bit better even though they are an all terrain and they are LT rated not P rated

Well as of now my 2015 All -Terrain is in for the shakes no bad but just enough to finally have the dealer look into it .3rd time I have commented about and have it documented on each visit , 1st time rebalance tires last year, 2nd time rotation and rebalance balance was out, finally this time they have it for 2 days so far balance is good next step they are connection the vibration test kit? with pile of sensors etc connected and driving it a round. have 35000 KM (Canada) 21000 Miles

also they are checking the lazy shifting of transmission at least to me it is. no matter the out come it is being traded in next spring. being for sale now and potential buyer have commented on the minor shake so as of now I can not even sell the thing !!

Plus seat belt recall and air bag recall done.

Up date Sept 19 truck was at the Dealer for 2 days they found no problems I may be crazy cause no one else feels it even my wife.

Best out come so far is listed it for sale Sept 05 before dealer visit and Sold pending mine and buyer schedule to work out. it will be gone by Sept 21. They felt no vibration at all on the test drive at highway speeds.

New poster here. I do have the same issue as well. I didnt notice it as much when I had the OEM 18' tires on. It got worse once I switched to 33s 12wide 20''rims OFF road tires. I did some tire balancing and then it didnt vibrate much in USA highways. However once abroad I do notice it when I go up hill or when Im doing off road. I do notice strong amounts of vibration when the pavement is not very well made. As If im about to lose control of the vehicle when im driving. My old Mazda 2001 truck piece of junk doesnt vibrate as much and its a diesel junk that vibrates on idle LOL. Im looking around the thread and cant find any solutions. Did anybody compile possible solutions or something to ease the vibration at least? Also this truck is no longer in the states. So Its impossible for me to take it to the dealer and get a fix.

Praying new tires help my ride. I aired up these good years stockers to 39 p si and seems take away the trembling that goes along with the Chevy shake. So considering trying an LT tire. And I'm still saving up to try new leaf pack for the rear.

Add me to the list of owners of a $50K vibrator. My 2015 High Country started vibrating at around 70MPH when it hit 9000 miles. I'm at 14K miles now and it is getting worse so I dropped it off yesterday. Received a call today saying the tech had confirmed the vibration exists and that the first step is a force balance at a cost of $230. I told them to go ahead and do it. The next step will be to look at the tires if this doesn't fix the issue.

 

 

What is really strange is that it doesn't always happen. I can be driving into work vibrating away at 70MPH, hit some traffic and slow down, get back up to speed and experience no vibration.

Tell them to stick that 230 up their asses. It's under warranty.

Not strange at all, been mentioned numerous times on this thread. I just hit 14k miles on my truck and the shaking has almost gone away. I might be one of the few whose truck got better with miles but it also points to my problems being mostly with the tires IMO.

Exactly

According to them, GM does not warrant tire balance. They people at the dealer aren't being assholes about it but I will drop it right back off if it isn't fixed.

Keep the receipt because it will feel great for a few days and slowly return. Get your money back when it does!

[LongrangeLauber]

Yeah I believe GM covers the tires, from having to replace them or to rebalance them, up to 12k. My dealer ate the cost of rebalance at 34k, they are awesome

[Schmidt152]

I don't see how they can charge you. I just had two replaced and all 4 road force balanced. Plus the front 2 re-road force balanced after I still was experiencing vibration. I left the dealership today and I'd say it's 98% fixed. I maybe just looking for it so much now that I don't know what fixed even means anymore. I swear I'm paranoid about the issue now, especially after reading this thread lol
