Default Installing LSD

Is it possible for the average home mechanic to install a LSD in the rear axle? I have basic experience, but not sure how to. Is there a good write up for me to follow? I've searched, but can't find it.

Thank you

You sure LSD is legal now? Just kidding. Dumb joke.

I can buy a LSD for $100. I can't afford a good locker.

Limited Slip Differential. It causes the other tire to start catching hold after the first starts slipping. Kind of like a locker, but doesn't kick in until the first tire slips.

Also called a Posi-Trac.

They're not really good in snow and ice, but in TX we don't get much. So I can deal with whatever small amount we do get.

My understanding is that LSDs are BEST in snow and ice. Lockers aren't. For street driving in bad weather, an LSD is a better choice than a locker. Offroad though, lockers rule, obviously.

What kind of LSD are you looking at, OP?

I wonder whether an aftermarket gear driven LSD (like the popular TrueTrac) would really function in the JK--the BLD kicks in when a wheel slips, which may "fool" a geared LSD into continuing as if no slip had occurred. The OEM LSD is a clutch style, so it avoids this issue though obviously also comes with its own problems. Just a thought.

It's a factory LSD out of another guy's Jk. How hard you think it would be to install and setup a factory LSD in another JK (mine)? Any advice?

LSD was a factory option. Whoever ordered my JKU wanted a mallcrawler.
