Default Wj dana 30 to jx?

Hey I wanted to do the steering knuckle break swap. My knuckles need replacing and the axel it self is looking like it's moved out a bit. Was wondering if I could swap the whole thing. Housing and everything? And if so would I still need to buy the his spacers to put on the xj hubs?

I think, and I could be wrong, the manuals had 3.07s. Autos have 3.55s?

Be patient, someone will confirm.

WJ 30's are low pinion, there's a pretty decent chance it has 3.73's, cv axle shafts, and I think they are wider. If it came out of a rig with a rezeppa drive shaft, you would also need a new pinion yoke. Not worth it IMO.

Correct!
If you have access to any parts of this WJ, then the brake booster is a upgrade unless your a 96+...anything older its an upgrade. The whole knuckles, calipers, and steering could be used and is a huge upgrade! You'd get dual pot calipers, and cross over steering! That stuff sells for a pretty penny.
