Hmm. . . I have a base model S14 and I think I have a. . .

[Jagstang]

I have a base model S14 SE and I think I have a factory Viscous Limited Slip Differential. . . But what confuses me is the fact that I though all base model S14's came with an open differential? I took this video to show you guys.

Btw, I had the ebrakes down, and the car was in neutral.

So is that a VLSD?

P.S. My car is a pure S14 basemodel with 4 lugs, no ABS, no rear stock sway bars, etc. I have heard of base model S14's coming with VLSD's. . But it was a package that included the ABS and the VLSD. But I don't have ABS. . .?

Sorry, but I had the ebrake handle down. And the car was in neutral?

[Dire91]

I've always wondered this too, I have a 97' SE and can't tell the difference.

Yes, me too brother, me too. . .

You should have someone apply just a little resistance to the tire you are not spinning by hand, I think you will find that it will not rotate while the other will. I don't believe your car came with a LSD. Or just go do some burnouts in some gravel and find out that way.

[Wretched]

Just look for the bright orange sticker on the diff. Or go do a big smokie and see if you leave two marks. The reason the tires are moving is b/c when it's in neutral there is still a little bit of drag in the bearings causing power to be transfered to the rear. It's hard to explain and I haven't cracked open a transmission in at least a year. Anyway, check the diff for the sticker, someone may have already swapped the diff.

Hmm alright, before doing the burnouts, i'll try your theory first (getting someone to go to the other wheel, and apply resistance).

I tried looking for the bright orange sticker, and could not see anything (mainly due to the fact that it's extremely dirty with grime, oil, etc)

Alright, and about your neutral bearings explanation, should I try spinning it in gear 1?

[ProjectGarage]

Are you the original owner? Maybe the old owner put a vlsd in...

[AZ89two4Tsx]

Just rev to about 5K and dump the clutch in first gear.

Are you worried about breaking something? lol

It's really not that difficult of a test dude.

I'm not the original owner, i'm the second owner... But the original owner gave me all the receipts since 1995, and there's nothing that mentions a differential swap. He only took the car to the dealership. . .

I know it's not, but where I live, there isn't any places to test it out :| I'll see if I can scope a hidden and quiet area.

just search 240sx decoder. and look at the vin and mid decoders,. it will tell you what your car should have came with from the factory

[anti_flag_army]

You want the easiest way to do it without a burnout, jack up the rear so both tires are off the ground. Take off the e brake, and rotate one tire, if the other tire goes the same way, its an lsd, if it spins the other way its an open

Oh man thanks a lot. I just checked it out with this site

http://my240.epijunkie.com/240...oding

And the 18th digit on my cars model ID (Drive System Options) is "A" which stands for a "Viscous Limited-Slip Differential (VLSD)". Sweet thanks so much, now I know for a fact that I have VLSD.

Yeah, if you look at the youtube video I posted, that's my car, and that's exactly what i'm doing. Thanks.

Oh i see, im at work and couldnt see the video. Then just have someone hold the wheel like it was stated earlier

[Dazzla]

You have a LSD...as do I. My car is a exact replica of yours.

If you don't agree then just do a quick burnout in your driveway...its not a big deal lol Rev it up and drop the clutch...if you have 2 tire marks, you get your answer lol

Yeah yeah, I just went out to do a burnout with my fellow nico naught Asoomal, and he did a 25 second brake stand in my car, and yup, two fat marks.

if you don't have abs i can tell you that you don't have the factory vlsd. if you do have one someone must've installed it before the car was yours.

although base models could be ordered w/ abs/vlsd package i still believe that you either got both of them or nothing.

Well, I checked the model ID of my vehicle, and it clearly says I have a stock VLSD. I know what you mean tho, weird, it should have included an ABS system.

open differentials can leave two black marks as well, the gears just have to catch at the right time

What? Hmm, interesting, i've never heard of that. Well i know for a fact it's a VLSD, first the tires spinning perfectly together (when the car is jacked up in the back), secondly, reading the model ID, and third the brake stand. I highly doubt an open differential would fluke out on the first and last tests?

[jeff420]

yea its a vlsd. open diffs the opposite tire would have spun the opposite wheel. of course you already know this.

[-RJ-]

jack up the rear end and spin a wheel. The other wheel shoud move the same way

If you look at my first post, I posted a youtube link (which shows what you've just said). That's my car btw.

[asoomal]

It's got VLSD.

[numbnuts240]

abs and vlsd were offered independently of each other. so it is, in fact, possible to have one without the other.

[Dazzla]

hmm...I have a VLSD too according to that link you posted. Mine is literally a sister car to yours lol

haha yeaa!!! Sweet man, good to know, seeing how you have modified your car more than mine, i'll keep my eyes peeled on ya. You're car is a futuristic S14 guinea pig for me
