Shaking While Braking With New Wheels And Tires

stlavsa · August 11, 2008

A couple months ago I installed a set of 20" kmc rockstars and 33" pro-comps on my 2008 4x4 ext cab. I was getting slight shaking when I would brake from 50+ mph, but I attributed it to warped rotors and I was intending on having them replaced.

This weekend I had the REAR - wheels and tires off of the truck, and when I put them back on (same wheel in same spot) now the shaking is drastically worse. This leads me to believe that this is not a rotor related problem.

I torqued all the wheels evenly and none are over-torqued. Whats the shaking all about?

Edit: What really nails it down for me that it isnt the rotors is that I had the Rear wheels off only this weekend, and it doesnt have rotors in teh back, and its still made the shaking worse

There are clips on the rear drums that keep the drums in place during manufacturing. OEM wheels have a recess designed specifically to avoid these clips, after market wheels do not. Unless these clips are removed, you will experience shaking while braking. Run outside and remove your rear wheels, remove the retaining clips with a screwdriver and some needle nose pliers (you can trash them) and you'll be golden. Once that's complete, find a new wheel and tire shop because the guys you are dealing with apparently have no idea what they are doing. This is nothing new whatsoever. Good luck!
