burnineyes...that is EXACTLY what mine does. Will sit there and jitter (hate that noise) until I slightly move the wheel. Once centered, the servo stops jittering. AE is sending another front gearbox, so I'm wondering if the pins will seat a bit tighter than they are currently. I was thinking of added a small bushing at the ends of each pin, or just glue them in since I have the aluminum steering upgrade that uses ball bearings.
