It depends on the condition of your ZJ box? If your not totally familiar with the tear down carefully review my tear-down and rebuild threads.
Things to look for on the box you wish to rebuild:
Inspect the sector shaft teeth for wear grooves from improper meshing.
Inspect the rack piston nut teeth for the same wear grooves on the teeth.
Inspect the sector shaft for needle bearing wear.
Inspect the sector shaft for seal grooving, (can be carefully sanded down without touching the needle bearing surface).
Inspect the sector shaft bushing on the side cover.
Inspect the sector shaft needle bearing for wear and excessive play, (replace it if there's anything over .005 play), This bearing can be a pain to locate but not impossible!!!
Inspect the worm shaft for excessive wear, (easiest way is to inspect the ball bearings, if all are silver then there's significant wear).
Inspect the rack piston nut also for thread wear from the ball bearings.
Inspect the worm shaft Thrust bearing for pitting, grooving and smoothness.
The rest is usually ok but if you have any doubts look at the pix of the assembly thread and compare them with those parts as they are in excellent condition.
If they all look good then it would be of benefit to rebuild your steering gear, and a fun project if you take your time with it!!!!!!
