Limited slip diff

[Bigfish_74]

Having nearly finished a wedge resto I'm in the fault finding phase, the car will not push forward ( and yes it's out of gear and handbrake off) it drives fine. jacked up, the rear wheels spin backwards but will not turn forwards (very slight movement) it's not the rear brakes locking on and it's not the UJ, having never had a limited slip diff im wondering if this is just how it's meant to be?

Weird... no that's not how an LSD behaves. If you jack up the rear and turn one wheel the LSD will make the other rear wheel turn in the same direction and turn the propshaft at the same time; non LSD would turn the 'other' rear wheel the opposite way to the one you're turning and not turn the prop.

I assume you have both rear wheels off the ground?

[Bigfish_74]

Yes both wheels off the ground, sounds like it is a problem somewhere.

If the steering is turned it’s hard to push with lsd because wheels want to do same speed

[mrzigazaga]

What about the prop UJ?

Some times the hand brake calipers stick going forward had this on someone’s car had to put springs in to help release

[Bigfish_74]

Thanks for the suggestions, I need pull it apart and see what I can find, hoping it's not a faulty diff.

Slacken off the handbrake adjusters - this will take 10 minutes to try.

Each caliper has a big slotted screw, and a split pin.

Two turns anticlockwise each side should do it.

If it frees up you've found the problem.
