My poor YJ was built without a limited slip and I HATE the fact. For a Jeep, it's pitiful in the mud and snow. My '88 Ranger is locked in the rear (previous-owner install) and it's absolutely incredible in the slippery stuff.

So...I was thinking about just a limited slip. First, any brand suggestions, and second, is this an install I am capable of? No, I cannot and have never rebuilt a rearend and don't know how.

Few of us know how or have the tools to build a rear end..
That said you CAN install a lunchbox locker in there..
I use POWERTRAX LOCKERS A couple of hours with two common tools and there ya are. Google for prices and delivery. Should be less than 300 bucks and works wonderfully.

I've been wondering about this too, will the stock rear end hold up with one? I'm running 32s.

For mud and snow it should do good with those tires..

93yj, IMHO a limited slip differential is simply junk for offroad applications. I strongly recommend a full automatic (as in always on) type locker for the rear axle.
I personally ran several years with a Detroit Locker in the Dana 35 with 33 and 35 inch tires over some of the most difficult trails in Colorado, Utah and California before replacing the dana 35 with a 1 ton rated axle; the driverside axle tube started turning where it goes into the differential, only the traction bar held the axle tube in place. I was fortunate to have been able to get the rig off the trail and back home, a distance of about 150 miles!
