Installed a one inch body lift to CJ7 today. Needed to replace 32 year old mounts and while I was at it, put in extra inch for some future mods. All went well with install. Daystar kit, who say that no need to alter clutch linkage, steering shaft, lines, wiring etc do to only inch lift.
Fired it up to take around the block and when backing out to turn noticed restriction in steering. Not major, is not total restriction, but is in the same certain positions, left or right. like the steering shaft is bent or something. Does not lock up, nor does it keep me from driving, and only requires little additional effort to turn past the tight spots.
Checked and the shaft is not touching or rubbing anything. Sprayed some lube on the joint, power steering fluid is OK. Whatever the restriction (if restriction) is seems to be after the shaft it enters the column going through the firewall. Turning signal work OK, etc.
All worked ok before adding the lift. At a loss as to what it is and how to fix.
You have to much pressure on the brgs in the column. The shaft has to slide, and sometimes it doesn't slide enough, and puts pressure on the brgs in the column. You can remove the pinch bolt in the upper you joint and try to take pressure off the column, if it frees up then you know that's the problem. You can try tapping up on the shaft gently at the upper joint with a plastic mallet.

I would think that even though it's only 1" of lift the steering shaft still needs to extend at the slip joint. This would relieve the tension you are experiencing. Take a propane torch to the shaft where the slip joint is. You will notice two "holes". Heat them and the material injected at the factory will expand and leak out, allowing the shaft to extend.

I put the Daystar lift on mine and had no trouble. The steering column bell coupler should have enough slip without extending the slip joint in the center of the shaft.
On another the OP mentioned, I would double check the clutch bellcrank alignment. Mine worked for a while then failed on a cross-country trip. He may need to lengthen the clutch rod and the bellcrank's body-mounted bracket.
