okay i searched around and from the answers i found, i am kinda confused! I have a 1980 SA and the back has DISC brakes.... at first i thought someone converted just the brake system over.... then i started going through this site looking at pictures of other SA and i see very few with my wheel... the cross looking setup. I havent tried yet, but i have a feeling that my front wheels would not fit on my rear hubs.... i have the strangest feeling that the entire rear end was swapped out with a gslse. how would i find out if that is the case without tearing the car down... i read something about the width of the pumpkin, but im not real certain. Did my car come with these wheels or did someone swap my rear end out and put some 4X114 wheels on the back? also look at the picture of the hub... there was a LIP there on the end which made it quite difficult to get the wheel off and it looks like someone grinded it quite a bit... where might this have come from?

If the + wheels fit and bolt up, then you have a non-SE rearend. Our wheels are hubcentric, not lug centric, so sometimes they tend to stick if left on for long periods of time. That wheel came out in 81.

okay i am not really certain what that means Trochoid... so this wheel did not come off of a 1980 SA???? so can i measure the pumpkin? or are there any other ways to find out what rear end i have? did the SA ever come with Rear Disc? i know this is a Leather Sport 7 but thats about all i know.... would the vin help?

Rear discs did not come out until 91, along with LSD. If that wheel in your pic bolts up to the rear end, then you have an 81-85 rearend, of which there is a small and large axle and bearing versions.

SAs came with waffle wheels, steelies or Almex wheels.

^ I have rear discs on my 84 GSL

'84-12A-GSL

I think Trochoid meant 81, not 91.

This guy must have a GSL rear end with a LSD and rear discs. Measure your bolt pattern, I assure you the front and rear are the same, 4 x 110. Those " + " wheels didn't come in 4 x114 as previously mentioned.

Or maybe you have an FB, not an SA haha

Need to quit typing in the dark, lol. Yes, it should have read 81, not 91.

no it is definitly not an FB the vin is SA. okay so the 4X110 was pretty much all throughout the 1st Gen??? i thought it changed over to 4X114... okay so i have a GSL rear end... i know i have LSD cuz when i lift the car up and turn one wheel in the back the other one goes the opposite direction. wow! this car has seen a lot more work then i thought!! its got the swapped rear end, poly bushings ALL AROUND, tokico blues all around, the Dellorto/RB system, wonder what else was done to it that i dont know about....

Both wheel should spin the same direction in the air if you have LSD.

1979-1980 SA's came with 4x110 bolt pattern as all first gen 7s did, but no rear discs and no lsd rear end wise. It's the same for 1981-1985 S, and GS models. I don't know about leather sports but I'm guessin the same thing. 1981-1985 GSL's and the 1984-1985 GSL-SE had rear discs and lsd.

so if i got rear disc but no LSD then what the heck happend??? did someone just do the conversion? or was there a setup that had one but not the other?

BlackWorksInc

I was under the impression that with our vehicles, it was LSD and 4 Discs or regular setup after 81.

Maybe someone just took the rear discs off another car. or if it was done when the SA was still new, maybe took the front discs off another SA?

If you don't have an LSD then someone problem just did a basic brake swap. Chances are though that they swapped the whole axle, so check to see that you have the LSD.

djessence

partially Incorrect info from twinkletoes on wheel patterns about all 1st gens. the GSL-SE's did not have 4x110 bolt pattern, They had the 4x114.3 which is FAR more common

so how do i find out if it is LSD or not??? if i rotate one wheel with the car up then is Justin correct? does the other one rotate the same direction?? or am i correct it rotates opposite direction. thanks.

BlackWorksInc

It should rotate in the same direction.

An LSD works to equalize the torque driven to a slipping wheel with the opposite wheel. In example, if your right wheel is slipping, the LSD transfers the majority of the torque to the non-slipping wheel to balance it out for you.((I think... ))

so my car does not have Limited Slip.... damn. that sucks... so it was just a rear disc conversion....

I have "lsd"

mikewoodkozar

Should be pretty easy to swap in the LSD rear end, but being in Hawaii, i dont know...

Last I checked the other wheel would rotate the OPPOSITE direction, when and LSD is installed.

poor LS

It may be worn out. The only way to tell for sure is to remove the pumpkin and take a look.

There is a way to test an LSD by jacking only one wheel off the ground and turning it with a torque wrench on the lug bolts to test for ft/lbs of breakaway. Don't remember all the details or where I read it.
