*Inserting foot in mouth* My front left tire is cupped on the inside edge. So Im guesing that is where my pulsating noise is coming from. I'm thinking my next project is finding out why they cupped. I have 50 K on my original shocks and about 10 K on my eibach springs. I'm thinking its time for shocks and maybe I will just replace the bearings while the car is in the air...I have read a few cases where crap bearings caused scalloping. My steering stabilizer is only two years old.
