Looking for some imformation on a rear locker/limited slip.... first off what is the difference between them, as I am looking to install one in my 98 4dr 2wd this is a 90% street & 10% offroad as in mostly forest roads up to the lakes & to go camping away from the normal campgrounds, in AZ. national forrest you can't use any road that is not a numbered forest road, without a big fine if they catch you, so not going to be jumping over rocks or such, I just don't want to get stuck in the middle of nowere.  So any info on which would be best??

I would save your money and learn how to use your parking brake real easy to give yourself limited slip if you just need it to get un-stuck.

What's the difference?

If you jack up one rear wheel and try to drive off the jack, with the locker you can, with the limited slip diff, it may attempt it, but will probably fail (there are different types of limited slip differntial), and with an open diff, the car will not move.

An automatic locker like a lockrite will lock both axle halves together any time one wheel is spinning faster than the other. A limited slip has a clutch that applies drag between the axle halves and therefore some torque to the wheel without traction.
The downside of an auto locker becomes apparent on slippery off angle slopes where it is advantageous to have one wheel firmly anchored to the ground and not spinning maddly as you slide sideways off the trail or road.
I vote for a savings plan that ends in an ARB locker, plus you get an aircompressor for airing up after the trail. Even if it is only 10% of your time.
BTW check out your BLM lands, Arizona had plenty last time I was there. 

... ...Wait a minute...2WD?!!!

An automatic locker like a lockrite will lock both axle halves together any time one wheel is spinning faster than the other.

Is that a fact?  So tell me what happens when you make a turn in an asphalt parking lot.

The way I understand it is the outside wheel, which will turn faster than the inside wheel, unlocks & ratchets.

What it does is prevent either wheel from turning more slowly than the crown wheel, thereby guaranteeing drive to at least one wheel.

The only limited slips available for the Zuk's are clutch type, and repair/replacement parts are NOT AVAILABLE.

Limited slips are best left on the pavement, and even then they are questionable during icey/snowy conditions.

2wd would be best with the ARB, I wouldnt run a lockrite in the rear of a vehicle that sees primarily pavement as a DD, you will hate it!

it should only lock when you are on the gas...not while 'coasting'

afa on a dd; no prob as long as you realize you cannot gas it while trying to turn too tight (like a parking space)
you coast while turning sharply and it will ratchet allowing for differentiation

Go locked or just leave it open.  I wouldn't bother with a limited slip, just learn to use the handbrake. If you're going to spend that much time and money on it, go for the ARB.

I was trying to be concise.
You are correct, a lock right locker does not physically lock the axles together any time one wheel is spinning faster than the other. However, when you are heading up a slippery off angle slope and both wheels start spinning, it will not matter how it functions in an asphalt parking lot. My point is it happens automatically.
If dectar99 finds himself in Flagstaff in winter, or any other mountainous snowy region with an automatically locking rear differential, he will need to exercise more caution, especially around uphill corners.
My apologies to dectar99 if he is a girl.

Thanks for all the imput... something to think about.... & yes it is a 2WD...LOL    Hay don't knock it, it works great never got stuck yet, & I had a 1976 Datsun PU 2wd that I went out with some friends, they had there big fords & GMC 4X4 & they wanted me to follow them on some trails, so when they got to a large hill they told me I could take my little toy truck & go around the hill & meet them on the other side.  In stead I watched them go up the hill & stop then I gave it a try, they couldn't beleave that I made it all the way up.... but I did tell them that I had to turn the A/C off half way up the hill....
So ya... 2WD is fine if that's all you got, make the most of it.

& yes it is a 2WD...LOL     but I did tell them that I had to turn the A/C off half way up the hill....
 

You wouldnt have had to turn the A/C off with 4wd, LOL

But yes sir the smaller zuks walk all over the large domestics.

The guys I wheel with all have domestics, they really despise it when they struggle massively and then I just skitter by without a hassle, what sticks in their craw even more is their women folk saying that want a Sidekick after seeing mine, so that they can outdrive their hubbies!

I had an '81 Datsun PU with similar stories. 380,000 miles on the original untouched engine, and it still would start faster than my Tacoma. I could take that thing from Oakland to Nevada and go exploring the desert mines and back again with no problem.
It is why I bought the Samurai. They sound the same when I slam the door.

How about "Lincoln Locker"??

ARB.  Let a little air out of the tires and it will go anywhere the ground clearance allows.  I do 95 percent of my wheeling in 2wheel drive and it is amazing where it will go.

locker without a doubt !
