Castor correction bushings issues (1 Viewer)

[J79]

I recently installed caster correction bushings on my vehicle, which has a 2-inch lift, and I’m noticing that the RHS drag link is now touching the radius arm. Both sides’ bushings were installed in the same orientation, so I’m struggling to figure out why this is happening.
Has anyone else dealt with this issue before? Could this be a sign of an underlying problem, or is it related to the suspension geometry with the lift? Any advice or troubleshooting tips would be greatly appreciated. Pictures are attached for reference.

I have a 4" lift on my J76, but I have castor correcting swing arms, not bushings. I have about an inch of clearance between the drag link and the swing arm.

Do you know what size lift the castor correcting bushings were made for? It is possible that they are designed for more lift than 2"? How does it drive? That would be my litmus test.

Either way, that should still be enough clearance as the swing arms move with the axle.

This is very common in the 80 series world and most move away from caster bushings.
Some have ( including me ) ground off the casting marks on the arms in the affected area. Just be careful not to take too much.
It’s 100% due to the bushings moving the axle making the tie rod closer to the arms.

You could also try just removing the rear bushings and run the OEM bushings. It would probably be enough for you 2” lift.

I didn't even think about keeping the original bushing in the rear, that's a great idea. Thanks I'll try it!
