Not likely to have Limit slip in an SE and even if it did it probably wore out, the factory units don't last much over 80,000 km.

Limited slip was not an option for a '98 SE.

There are a couple ways to verify if a limited slip was installed, either by a previous owner or maybe even a factory mistake:

1. Raise the rear tires off the ground. Spin one tire and watch how the other tire turns If the other tire turns in the same direction, you have a functional limited slip or a locker. If the other tire turns opposite or remains still, you have an open diff or a limited slip that is no longer functional. Sometimes you have to put a little resistance on the opposite tire in order for the limited slip clutches to grab and turn the opposite tire in the same direction.

2. The best way to know for sure is to open the diff cover and look at the shape of the diff case.
Open on left, Limited slip on right:

see my axle was replaced and was off roading and seems like both tires were spinning going in mud and up a rocky hill... in sand both rear tires were spinning, yet in the winter only one tire spun in loose snow...

An open diff spins both wheels under certain circumstances. When the traction is equal, both tires turn.

And a limited slip will only spin one wheel in certain situations. Once the traction difference between the 2 tires becomes too great (for example 1 tire on snow, the other on ice) a limited slip will behave just like an open diff. That is why most people who wheel their Jeeps prefer a locker. So you always have both wheels turning.

In other words, its hard to tell for sure if you have limited slip based on what tires are spinning and when.

apparently the P.O. daughter got a parts jeep and it was a Rubicon, newer and bigger... the drive train was all that was good left in it, so she got the axles seitched in the rear as the origional broke...

I had an 01 TJ that had a metal tag on one of the rear diff bolt warning to only use limited slip oil...that's how I found out I had one.
