Does the sound come more from the front end area or closer to the actual steering wheel?
The lubed my i-shaft and all that, but the noise constantly comes back. I recently had a knocking that wasn't from my brakes or rotors either and something just seemed loose or something... turned out to be my steering rack.
How bad were your brakes getting before you fixed 'em? I waited a little too long on mine, and it makes me wonder if some of the looseness/badness/knockiness from the brakes effected/loosened up the steering rack... or if both things just happened at the same time. Not that they are necessarily connected or ever really effected by one another, but the knocking was from the same area and it's hard to say when it started. Just curious. I even felt like I had better braking after my new steering rack, but I think it was because the steering rack was just getting that bad, ya know?
