it seems to happen at all speeds, just dependent on pressure. lot more noticeable at slowing down from 50 or so though. i don't notice any clunking noise or bumps at low speed. so you guys are saying ball joints + thrust arms + 750il bushings ? good time to install those racing dynamics sway bars i have sitting in the garage too huh??
If your ball joint was shot like mine was you'd have the clunking. Check your rotors for run out as they may be warped. Don't buy anything until you KNOW what the problem is.Quote:

run out- a big lip on the outer edge of the rotor. It is an indication of how much material has been worn away where the shoes contact the rotor. If you've worn away alot of material, they're more likely to warp. Just look at them from through the wheel or take the wheels off and get a good look.
Also, if you don't have the clunk or the shimmy, I'd hold off on assuming the thrust arm ball joint is shot. Could just be rotors and maybe a bad caliper.
how much is "big" ?
i don't mind changing the pads/brakes or the arms/bushings too much, since i plan on autocrossing it once it's nicer outside than the 0 degree weather we have now!!
big would be as thick as a paperclip.
