horrible vibration on front end

Ive been chasing a vibration in the front end for a while. Every front suspension peice is new except the hubs and steering rack. When i apply the brakes, i get a horrible shimmy and very audible vibration. The car does not pull to either side when braking, but applying the brakes quickly at higher speeds, yields a very noticeable vibration. The car did this before the 13inch brakes, i thought it was warped rotors and low pads, but it has been consistant after changing to the 13inch brakes....its gotta be the hubs...anyone have any thoughts?

Hubs... hub bearings maybe. Have you examined your rotors for hot spots?

no i havent..also, i just thought of this...when i go over bumps and the metal guide rail for the gate at my apt complex, the front end clunks with a metallic type sound..i havent "examined" the rotors so to speak..just eyeball them when i wash the car or when im doing something car related to burn up some time.

if the rotors have been recently turned the mechanic that machined them might have just cut deep enough to make the hot-spots disappear visually, but there's no way to get rid of them once they're in the rotor.


I have the same sound when I go over bumps and other "imperfections" in the road, so to speak, and I've always attributed it to messed up bushings. Since yours are all new, I'd take a hard look at the hubs and the hub bearings. But I'd think they'd show any problems by vibrating at speed as if your wheel was out of balance.

But assuming everything you replaced is still in good condition, the only thing left to do really is check the stuff that hasn't been replaced.
