hey , i was getting freaked out starting saturday morning when i pulled up to a light and heard a faint knocking sound. i popped the hood , and i was relieved to hear that its actually coming from either the powersteering pump or compressor. i cant tell which though . anyone have any ideas? on a positive note. i went down to n.c. this weeekend and picked up my s15 truck that had a tranny blowout. towed it with a car dolly and my k5, 250 miles , no problem.
