I have an 02 f250 with the 7.3. I recently had a buddy replace the ball joints and had an alignment done. Since then, I've noticed that the steering doesn't not return to the straight position after a turn. When I let go the of steering after a turn it goes back a bit but then continues turning. The ball joint guy said toe in alignment is off. Alignment guy said ball joints weren't greased. Any ideas as to what the issue is? The ball joints are ROI? Brand and one says they are packed with grease from manufacturer and other guy say no??
