i have the famous chevy shake ..

truck is RCSB 2014 1500 z71 .. only 5600 mile so far

it was originally a vibration after 72 mph and above , now it vibrate like it have pulses go through the chassis it feel like it go strong or it goes half away ,

it also ride stiff and harsh that's with bilstein 5100 and 17" fuel wheel and tq the the U-bolts to 80lbs gm spec , everything els is great

anyone tried to fix this and worked with him ?

Mine shakes between 55-65 I am fixen to have my driveshaft checked for run out and balance. I don't think it's the shaft but I'm going to rule it out.

Weren't some of the issues with the actual rear axle shafts?

Like they where out of round, I thought I read that somewhere.

My truck is a 2015 rcsb 2wd, 6 speed auto/3.08 gear. I'm dealing with this as well. Dealer replaced a few tires, rotated, balanced blah blah blah. I bought new wheels tires, no change. It's a side to side vibe, the flipped down center console shakes like crazy. I'm thinking drive shaft? I just scored another axle To try after that I'm going to look into an after market drive shaft.

Got it too.

Yes I have all angles in tight tolerance as far as drive line chassis settings. I am going to do the driveshaft, rotors, and axle shafts to nail it down. There is no reason for this BULLSHIT from a Big 3 Manufacturer!

Mine was fine until I flipped the rear, been through 2 different kits, same ****.

Prior to flip had done the following with NO vibrations.

2in Drop Shackle - then
Removed block - then
Remove OL spring - then

decided wanted more of drop = flip kit.

None of the above caused any vibrations, installed DJM flip. Removed the DJM flip, installed the BellTech flip. Still have vibes in rear.

Both of these company suck as far as support goes with their response to issues with the products.

Going to return the BellTech flip too and just go back to the shackle with the block removed.

Depending on what they tell me about my no start issue I may have time to have mine looked at. Sure would be nice to get it nailed down. Its not the end of the world if not, but damn.
