Does My 97 240 SE have an LSD??

[Lepchitz1]

I have a 97 s14 SE....do I have a LSD??? I thought I did but I was at the track tonight and someone told me that only one wheel was spinning....i thought they were both spinning cause there was a ****load of smoke from both sides...so please help!

i doubt you do. i have a 96 se (stick) and i had a 95 se (auto) before that and i didnt have it on either one. i think its very rare to find a s14 with lsd. i thought both of my wheels spun too, but do a stand still burnout for a few seconds and you'll notice only one spinning and only one mark, there will be a little second one, but only from when you first start it. ive experimented with mine a few times, its most liely gonna be your right wheel doing all the spinning due to the weight on the left from the driver. you should also notice one wheel going bald quicker than the other. if you cant do a stand steel burnout post back with auto or stick and i'll tell you the easiest way.

Well...people told me that it was my right tire that was stopped...i think it is because i hit the brakes a second cause i started sliding sideways...my tires wear evenly, and I have been told by others that the 97-98 models DO have the vlsd. Plus...it is a little odd if my left tire is my grip tire. I think they just glanced at me when i had to hit brakes. Anybody else??

Take it somewhere.... do a burnout and check your skidmarks.... if you have two.. then you have an lsd.... i'd be very surprised if you didn't... but i think you do...

There weren't certain years that had LSD and certain years that did. All the S14 SEs had the option to get it from the factory. Check to see if the orange sticker is on the diff still that says it's VLSD. After that, you can use this model number decoder to see if you have it as well:

Also, this has been mentioned many times, you could search for it =) Had to be said

Also, there isn't one side that is designated as a "grip" tire. With an open differential, power is transferred to the side that is easier to turn, so it could be either side.

i'd still be surprised if he didn't....

the site says it all. just change the year for your car if its different.

ok...heres an update. I DO have an LSD. I performed 2 tests. Test 1: Jacked up ther car and drove the car...both tires in rear spun at equal speed. Test 2: LEt em' rip on a back round by my neighborhood from a dead stop and left two tread marks the same length and everything so I think the question has been asnswered...thanks for all the help!

Will, sorry to burst your bubble, but you DON'T have LSD. I looked at your car, no ABS, so no LSD. Both options were always included together on the 240, you don't have ABS. An open diff will spin both tires under certain conditions, but that doesn't mean it's locked. Jack up your car, put it in neutral, and spin the wheels. If they turn the same direction, LSD, opposite, it's open. Chances are you didn't get a surprise with yours. Equal speed on the wheels in the air has no bearing, try and grab one when they spin and see what happens.

That's wrong. You have to put your car into gear to lock the driveshaft in place. If you allow the driveshaft to turn, spinning a wheel could result in spinning the driveshaft, which would prevent the other wheel from turning the opposite direction. You have to isolate the movement of the ring and pinion gears so only the differential itself will actuate, so you have to prevent the driveshaft from turning. And both the VLSD and Open diff will spin the wheels in the opposite directions. The VLSD will be harder to spin though. The VLSD and Open diffs are essentially the same, except that the VLSD has a viscous coupling to make it harder for the differntial gears to turn.
