01 xj rear in 88 comanche

[gnx1117]

Does the 2001 cherokee rear need to be modified or just brute strength?

Truth be told I pushed pulled banged and finally got it in. Is this bad?

I can rebuild the old one. Any help i am grateful

Yeah, the perches need to be flipped and realigned with the mj leaf spacing, unless your going SOA, than they just need to be spaced correctly. Either way, cutting and welding is required. And while your at it, minaswell cut those huge shock mounts off and weld on some nice low profiles to give you some extra clearance.

I assume by this you mean you forced your springs out of line and installed the Cherokee axle into your Comanche as a spring-over-axle conversion, without relocating the perches. Yes, that is bad. I recommend that you not drive the truck that way. You are putting a lateral loading on the springs and the spring shackles and bushings that they were not designed or intended to handle. As PFCLeist already commented, you need to cut off the spring perches and relocate them on the axle.

 

Was your MJ originally set up as a spring-over-axle? Why did you replace the original axle -- did it fail, or were you hoping the Cherokee axle would be a bolt-in SOA conversion?

Don't risk it. Relocate your perches. I have an 00/01 Dana 44 rear in my 87. Awesome axle. Just a little grind and weld for a great update. And you can buy perches cheap.
