The Wife has a '98 ZJ Laredo, and I have an '88 MJ Pioneer, and am 'unwrecking' an '88 XJ Pioneer. There is a METRIC TON of info here for the Xj and the ZJ, but it looks like my MJ is an ugly step sister! It's a shame really because the MJ is a HOOT to drive!

 

Plenty of folks here have MJs. 89eliminator is a mod, look up his uber long build thread.

JeepCoMJ is another MJ guy, but he's not on much lately.

 

there are a few guys here with MJ knowledge. but there are a lot more here....

I knew there was a site geared for them. That will def help.
