hllon4whls is right.. that is not good at all. Even my old rearend, which i found to have 0 friction material left on the clutches, both wheels would spin the same way when you turn them manually. Same goes for my freshly built rear..

If your tires spin opposite directions, i would assume it's got some issues. Chevy rear ends work like that though, wheels spin opposite as apposed to the same direction. Obviously a problem

Nope, the differential is working just fine and is supposed to spin in opposite directions in normal free-wheeling operation. The only time the wheels spin in the same direction is when the clutches are engaged. They only engage when they see a load at the wheel. There is no load when you have the tires off the ground

The only exception to this is whe the clutches are shimmed tighter than facory spec OR an F series pickup spring has been installed in place of the factory spring to increase clutch preload.

Don't forget you'll need a different master cylinder for that rear disc setup.

oh yeah, I know, thanks! that and a prop valve- and where can I get the right parking brake cable? anybody know?

This is really getting confusing, but I just though about this, how is it that when I spin the SVO rear I have on jackstands, it spins the same way, does that mean its been shimmed? same goes with my limited slip on my 69 coupe- I know it's not at all the same design, but i though it would do the same..

You rprob have to rebuild the traction lock. It is very easy to do. As soon as you get the s clip out and the axels, the rest just falls apart almost. Goes together almost as easy

If I go towards rebuilding it, Im assuming I just yank on that S clip, right? then the spider gears, u just spin out, right? I have a chilton- just not too much info in there though, thanks guys!
and OHHH!!! HAPPY THANKSGIVING!!!!!!!!!!

Any stock 5.0L GT/LX that I've seen with a working Trak-Lok unit had both tires spinning the same direction. Any unit not working I've seen them spin opposite directions. It's as simple as that.

The way the limited slip differentials work is that when you're going in a straight line the "clutches" aren't slipping, so they lock both wheels in the same direction. When you turn a corner though, one wheel HAS to go a different speed (travel more distance) than the other.....when that happens the clutches slip to allow the other tire to travel faster.

P.S. - You will notice on full locking differentials that when they turn a corner the inside tire will "skip" along because it's travelling the same speed as the outer tire.

First you have to take off the drums and push in the axle so you can get the c clips off then slide the axle out so it will clear the s spring which is in there pretty tight. You also have to remove the pin which I think is an 8mm bolt. Then you can remove the s spring.
