I have a '07 Supercrew Lariat 4x4. 20" wheels with the Pirelli Scorpion ATS and about 110k on the clock. I get a vibration under braking...sometimes. Usually when braking above about 35-40mph. Slower stops seems to be fine. Within the last 10k miles I have;

Replaced all four shocks with OEM
New Rear pads and rotors (auto zone stuff)
New Front rotors- Napa Ultra Premium
New front Pads- Napa Premium
New lower ball joints- Moog
New Upper control arms- Moog
New Tie rod ends- Moog
Had the wheels balanced and rotated twice.


None of this has cured the problem. What am I missing? The truck rides like new but brakes like crap. It does not pull pull when braking. It stops straight and true withou hands on the wheel, it just shakes and is driving me INSANE!!! any advice on what to look at next would be great. IS this a steering stabilizer issue?

Oh I also tried pulling the ABS pump fuse and it had no effect.

 

I had this problem on my '04. They changed my front rotors and calipers and that fixed the problem.

 

good call maybe a sticking caliper is warping your new rotors. check and make sure your sliders are very free

 

Had the same prob on my old '05, dealer replaced both front rotors under warranty. You wouldn't normally think bearings - but maybe?
