Just changed pads and rotors on my car. Apparently I didn't torque down driver side front wheel. Went less than a mile and not over 20 (leaving neighborhood) when I heard the wobble. Went home and found that I hadn't torqued the wheel all the way down. After inspection things look ok. Some small shavings from wheel where bolt (VW) threads were digging in. Threads on bolts and hub appear to be fine. Mating surfaces of bolt taper and wheel seem fine: finish missing but no bad gouging or slop. No cracks in wheel. Wheel bolts up and torquea down fine. 2nd test drive seemed good. Anybody ever done this? Is their a SOP for this in the pro wrenching world? What did I not check and/or what do I not know?
