how is it done? i know how to do it in a regular rear end because i took the shaft out to swap it into my current rear end, but i have a posi now, so i`m sure its not the same procedure

What rearend do you have?

probably just a junk ass gov bomb, "rebuilt" by Jasper. they're known for taking engines, trannys, and axles, just fixing what is broken, and selling it (at a higher cost than most rebuilders) as "rebuilt".

i've known people who worked there, reusing bearings, rings, and other parts that most of us would automatically replace while opening up an engine is an all too common occurance.

my buddy had a 4.0 in his Grand Cherokee.... actually 7 of them (all replaced under warranty) rebuilt by Jasper in an 18 month period. all stock daily driver GC, that occasionally pulls an 8' utility trailer. finally got tired of their crap and after installing engine #7 traded it on a Lincoln LS.
