Cherokee gear swap....how hard

hey guys, i've located a gold mine at my local junk yard area. They appear to have several 4cylinder cherokees in stock w/ the D35/D30 combo. What are the odds these babies have 4.10 gearing? how difficult would it be to swap out the gears into my '93 wrangler w/ 3.07's??? i'm pretty sure i have to remove the ring, or would it be easier to just buy the entire carrier assembly and swap that directly into my diff? also, how difficult is it to remove the pinion? do i need special tools or can it be done with a large rubber mallet and some creative wrench work? anyone that has a list of tools i'll need to get the job done, thanks in advance.. what should i be looking for in terms of not-so-obvious damage? how much do you think the yard will charge?

also, which models came with the LSD in the rear (yes i know it's a POS...) just wanna know

al

I don't know much about the 4cyl. cherokees, but I doubt you're finding 4.10s on a stock cherokee... could be wrong though.

In any event, its gonna be a lot of work removing the parts you need. Yes, it would be easier to take the carrier with you, otherwise you'll need to pull all the bolts that hold the ring gear on... and these things can be pretty tight and you'll need someone to hold the carrier while you whale on it (impact gun makes short work of this). Pinion will be more difficult to get out. The pinion nut is on there with a lot of force. You'll most likely need an impact gun to break it. You can try a rachet with a long b!tch bar, but trouble is keeping the pinion from spinng while you put force on it.

As far as inspection, you'll wanna inspect both the ring and pinion teeth for chips and pits and marks on the surface where the two mate. You'll want to look for a normal wear pattern. and you'll also wanna make sure gears haven't suffered from "burned gear syndrome" were the diff was run with low fluid or something like that and caused the ring gear to get too hot thus weakening it forever... the gear will have an abnormal apperance (kinda hard to describe) if this has happened.

You will need a new install kit (consisting of shims and stuff) before you put these gears in your diff... there are some parts you can't reuse (crush sleeve). And you can't just slap these in your diff the way they came out of the old. You'll need to have tolerances checked and adjusted. If you are not familar with this, you'll need to have them installed by a professional (this is not a DIY job).

brand new gears would run you only $150. I'm not sure how cheap your getting these for, but most people would just assume by new gearset rather than scour the yard for them.
