Truck bounces when braking
When i hit my brakes when decelerating from 42mph down to about 35mph my truck just bounces up and down violently and i'm tired of it. I have practically brand new rotors on, got them back in march and they have about 15-20k miles on them, and they are still perfectly straight, no runout at all. I replaced the front brake pads the other week with wagner thermoquiet ceramics, the rear pads are fine, but they do squeak and im thinking about replacing them with some tq's as well. I have no idea what this can be, but when my truck is cold and not warmed up, when i brake from 42-35mph the truck doesn't bounce at all. However when its warmed up and after frequently stopping between those speeds, it bounces regardless. Anyone have any idea what it could be?
I think partial fault may be my shocks, I have been meaning to replace them, but i'm tryin to find some lightning rear bilsteins for a good price.
Thanks in advanced

Warped rotors on the rear will cause the rear to bounce up and down, due to the grabbing and releasing causing the leaf springs to flex back and forth thereby raising and lowering the rear of the truck. The 2000 truck I used to have did this at 40k and I replaced the rotors with cheap advance rotors. It started doing it again in about 1000 miles. I got the original rotors resurfaced and that fixed the problem until I sold it 25k miles later.

bringing this up, i replaced my rear shocks and it did nothing, but the other day, i did look at my rotors and didn't see/feel anything wrong, however.....my outer brake pad was about 2/3 the thickness as the inner pad. i'll figure it out and post up what was wrong when i have the time.
As for the original post on vibration, take your wheels off the front. Use two hands to grab the hub and see if you can shake or lift it. If it feels loose, then you have a bad bearing. Bad bearings will cause the tire to shake or hop pretty bad.

I had this issue with my '06 Silverado. Started happening a few days after I put new wheels and tires on it. I tried numerous things but could not solve it for the life of me. Eventually had to put the stock wheels back on and it went back to normal. Might be an issue if you have aftermarket wheels

lol i know travis
stock wheels, stock size tires, new lower ball joints, wheels are balanced, and i am 4wd so....do i have bearings in the front or what? i've heard many mixed stories saying i do and i do not. so im not sure about that at all. in the rear, i more then likely will replace them or just grease them.
