XJ 44 into a TJ

I am putting in a XJ Dana-44 Limited Slip TruPosi 3.73 into my already Dana-44 3.73 (spyder gears) TJ and was just wondering if anyone knew if there was anything extra required or if that didn't work.
Any help appreciated

You are simply replacing your open differential with a track-loc right?


You'll be doing a Full gear set up is all
Measure current gear back lash, and take a reference pattern.
Use your gears,start with the original (to your current tj axle) carrier shims with new bearings, measure backlash and take a pattern. If it matches the original numbers and pattern, tie it up and drive. If not you'll be doing a gear set up.
be sure you use new ring gear bolts and follow the spicer set up manual.

Never mix n match a different ring gear and pinon.

Thank you man. It's arriving tomorrow. Stoked. I've been Jeep-less for a month.

Are you rebuilding the limited slip before you install it? I probably would.

Are you sure you do not already have a limited slip? Most TJ D44s do.

See that's what I thought too, but I have spider gears, not a spool. So I guess it could be limited slip just not a truposi (which is ironic because it is not an actual posi)

A stock TJ limited slip (Dana/Spicer Trac Lok) has spider gears.

I'm not sure what you mean by truposi? Posi is a GM term for limited slip.

Maybe you mean Truetrac, the limited slip diff made by Eaton (formerly Detroit)?

The guy said TruPosi but as you stated and on my own investigation of it I'd assume there is nothing special about it. I was confused at first cause I just started learning about rear ends when mine blew.
