Title: rear end options in 76
Post by: spyville on March 03, 2012, 01:50:56 PM
Hello. I was wondering if anyone knows if a limited slip rearend was available W/ 4 cyl as an option? The rearend I have is a limited slip and has the removeable carrier , I believe it to be an 8 inch. 

So would it have been an option?
Is there a definitive way to determine if this is a ford or borg warner limited slip?

Thanks

are there any bolts on the back side of the rear end? if so its a 6.75 rear, if the bolts  are on the inside by the drive shaft it is a 8inch. as far as limited slip goes not too sure with out the tag numbers off the rear!!!

hope this helps

Here is a picture of an 8 inch and a stock 6 3/4 (on the ground). I don't know if the Limited Slip was a pinto option (my guess is yes but rare). The easiest way to tell if you have a "posi" is to turn one side of the wheels. If both sides turn in the same direction, its a posi. If they turn in different directions, it's a standard one legger.

The bolts are on the front, it is definitely a posi. Both wheels spin. Just seems strange that a 76 pony with manual steering and no AC would have a posi?

The real question is, do they spin in the same direction?

The true test is not whether they both spin in the same direction - you have to try and HOLD one tight while turning the other. IF you can't keep it both moving, it's a posi.
I have an 8" rear end from a '78 six cylinder that I thought was a posi, because both axles turned in the same direction. It is not. A true posi will turn both axles regardless of whether you try and keep them from moving. A non-posi can turn both in the same direction, especially when off the ground, but it is misleading.

Great point and clearification with factual evidence! Thank you for clearifying this Chris, I will be using this tip next time I find a nice 8" at the junkyard.

Thank you everyone for your help.

Mine spins one tire one way and the other opposite, when it is off the ground. I cant hold one and spin the other . The reason I thought it was a limited is that both tires spin when I, ummm, when  my foot slips off the clutch when I happen to have my foot the gas pedal.

I had a ranger that would spin both wheels sometimes but it had an open diff. I did some google-ing and it can happen to a one legger if the correct amount of  traction (or lack there of), under hard acceleration.

I repeated the accidental foot slipping off the clutch several times over the past few weeks to determine if traction was a factor. ( for purely scientific reasons) It seem that both wheels always spin.
I found a lot of information about posi VS limited slip some say its the same some say its a generic term. Some say each manufacturer used it own term.
