Someone tell me if either one of these are LSD's
 

One is off a 89 GXL, other is off a 91 vert. I was told one is a LSD, I don't think either are. Someone confirm this.

No, those are open differentials... Now those MAY be LSD's that are broken... I'm not saying this because of the way they look (I'm sure the LSD's look diff) I'm saying open differential on the sole fact that they are spinning in opposite directions. I have an 89 GTU which has an open differential, and they spin in opposite directions. Limited slip differentials will spin in the same direction.

Anyone else have opinions? I need as many as I can get to proove my case.

Theyre either open or LSD's that no longer limit slip...

From what I remeber S5 GXL and Verts come with open diff, only Turbo model came with LSD.


Icemark can confirm or correct this.

Those are definitely open diff cases. An LSD case that no longer limits slip would actually likely turn the other wheel in the same direction slowly, or not at all. You might also get some grinding in the spider gears on a burnt out LSD. The fact that both cases appear to be functioning identically only strengthens that fact that they are both open diffs. Good Luck!

The only s5s that came with LSD would be the t2 or the GTUs.

The way I test for an LSD:

with wheels up in the air and car in neutral (or the rearend on the ground), turn the driveshaft flange...both wheels should turn the same direction, the same amount. If not, this points to an open diff, or a worn LSD.

Next, grab one wheel and spin it. the other should spin in the same direction, the same amount. If not this points to open diff or worn LSD.

Finally, grab both wheels at once and try to spin them in relation to one another. IF they are locked together and spin the same direction without slip, this is a good LSD. IF they slip, one wheel turns opposite the other, or one wheel doesnt turn at all this points to an open diffy or worn LSD.

LSD's that don't work properly are really are...they hold up pretty well.

any more opinions?

They are both open diffs! I will bet my TII on that!!
The LSD diffs look slightly different!

That test doesnt work. You need a certain amount of preload (Resistence, IE: The weight of a wheel sometimes is enough) to activate most LSDs.

Tho, testing it that way works most of the time, it doesnt work all of the time. My LSDs: both wheels spin the same way on my supra and on my RX7. But a GTUs rear (vLSD) I have only spins the same way if you have wheels on it.

Exactly. Both my Torsen rear end, and GTUs rear did the same exact thing as show in the video. You need to have some sort of preload in the LSD for it to work. Holding one side would even be enough. A better test is to turn the pinion flange and see what happens, with one side of the rear end held in place.

How would this work? I dont understand how the LSD and the open would preform differently.

I think that will tell you the difference between an open and a LOCKED :-p

If I turn the side where the driveshaft connects, they both spin the same direction, if I stop one side, the other side will spin 2x as fast. The diff on the left is off a 91 vert (diff in question), other one is off my 89 GXL bone stock(definately not a LSD.)

THE DIFF I SENT YOU WAS AN LSD! I cant down load the video but its irrevalent. i know what a damn non lsd is. Also FYI the turbo diff is a totaly different from the the NA both lsd and standered are smaller.

Thank you someone that understands these things. The Na and Turbo LSD's are totaly different

Thank you... The guy bought a lsd for 36$ on ebay! what a deal

HEHEHE want to put that title on the line.. JK take care

Didn't all GXL models have an LSD?...

The difference in appearance is due to the fact you are comparing a turbo LSD to any n/a rear end. It will look different than an n/a LSD or open diff.

N/A LSD and N/A Open look exactly the same externally.

Only S4 GXLs had LSD. S5 GXL = no LSD. Not sure about the S5 vert, but I'm pretty sure it didn't, only the S5 TII and GTUs, as someone else has already stated. And anyway, why do we need all this arguing? If they are LSDs, they will have a tag on the filler plug that says "Use LSD oil only" or something similar.
