XJ 8.25 swap Q?s

[A-man930]

So I found a low-miles 8.25 out of a 2001 XJ. Just wanted to do a quick check and make sure I had everything down before I break out the welder. I'll need new spring perches on the correct side of the axle tube, and new U-bolts... let me know what I'm forgetting.

you'll have to oval out your shock mounts (the base plate that the ubolt goes through) to accept the wider diameter ubolts, and the 8.25's brake line also. other than that, you should be set. I'd replumb the brake lines while you're at it, and also check out the brakes. you'll need to reset your parking brake while you're doing this (loosen the cable, then reset once the drums are set)

 

not a hard swap really.

I assume you know, but I'm just making sure, the perches are also a different distance from each other in an MJ. Don't just weld the new ones directly below the old ones on the XJ axle. :thumbsup:

Shock mounts of coarse...

My buddy mentioned something about measuring the pinion angle before we put the new perches on?? And yea, I was planning on making sure I got them the right distance apart.

What is the difference? I'm going to put my 8.8 out of the MJ under the XJ so I need to replace the perches. So would I have to cut off the pearches to fit the new ones or can leave them there?

You might have issues with the U-bolts interfering with the old perches.

Damn was hopeing to just bolt her in. Well going to just cut and reweld perches then. no big then this way I got ensure got good pinion angle as well.
