My Silverado front end wobbles at any speed, not affected braking

I am not familiar with your ABS as to how it is fed to the brakes but I am pretty sure I know what you are talking about. It sounds like your ABS is activating which is in my case the wheel hub. You will notice a wire harness coming down to your wheels and where that attaches is usually where the problem is. (problem being if I am correct when you brake you are getting a rapid pulsing rather than a smooth brake)

Most likely brake rotors are warped, have them cut or replaced.

I had that same problem on my Toyota pickup once and replace the wheel. No more problem. Wheel must have had a certain warp to it. Normally though, this wobble you feel would be a burnt spot in a rotor. But you've replaced that.

The notorious "Death Wobble". You need to go out and buy 2 stabilizer links for the front end. They look like glorifed shock absorbers. One end attachs to the frame and the other to the drag link. You need 2, don't bother trying to cheap out with 1. There's a reason why they call it "Death Wobble"

if its while you are applying the brakes it will have a warped or bent brake disc/rotor this is called brake shudder

it could be the shocks but due to wheel wobble i would say its more to do with worn bushings on the suspension arms etc.... best way to check is to jack up each front corner of the car at a time and shake the wheel see if it has movement side to side or front to rear if so i would reccomend getting it looked at or replacing the bushings :) hoep this helps

you need to have your tires checked for a slipped belt, also if you get a shake in the steering wheel when you apply the brake you need to have the brake rotors re-surfaced or replaced.

I have had the same problem ever since I bought my 4runner new in 99. I've tried all kinds of tires, constant balancing, rotations, alignments, brakes, you name it, I even have a new front end now, but still have wobble in the front end. It's acts like having loose tie-rod. NoOne can figure it out. LEMON?

your brake rotors are most likely warped. replace them maching them only makes the problem worst

did you have the front brake rotors machined, they are warped. either replace the brake rotors or have then machined, I prefer just replacing them as they are fairly cheap.
