68 alignment
1. The alignment was done incorrectly, or
2. The strut rod/camber rod came out of adjustment, or
3. He's got excessive wear on the end of the stub axle. The stub axle and half shaft assemblies are both a drivetrain component AND a suspension component. Think of the half shaft/stub axle as an "upper A frame".
When the stub axle wears within the differential, the top of the tire goes inward, increasing the negative camber. This wear cannot be compensated by adjusting the strut rod on the bottom. Think of the strut rod on the bottom as a lower A frame.
The solution is to replace the stub axle. Sometimes the ends are worn so much that they are worn down to or below the "C" clip groove, and you find the "C" clip or what's left of it within the diff.
This is why you often see the strut rods bent.... It's done to make them "shorter" to compensate for the stub axle wear. Ham fisted mechanics bend them to try to get rid of the negative camber created by the stub axle end wear.
Chuck
Examine the camber adjustment cams/bolts. Replace and/or tighten to proper torque. Put Loctite or ThreadLocker on the threads. Replace the split lockwashers with new ones.
