Steering All Over the Place at 55mph+

Don't go by the Moog instructions when installing them. Those are to move both points outward, for a car that had the mounts pushed in from an accident. Install so the fwd one moves the UCA as far out as possible and the aft one as far in as possible. The $1200 shop cost shows why most people here do such tasks themselves. You can rig a press with Grade 8 bolt & nut, thick washers, and plumbing couplers, all from Ace Hardware.
