Is my LSD tight??

[Gunns VC]

Hi guys, I got a vs berlina wagon it has an LSD but I don't know how to see if it's tight or not. When I jack the car up so both rear tyres are off the ground I spin one wheel and the other spins the same way. Now if I get someone to hold the other tyre I can spin the one on my side but it's fairly hard to spin it! Should I be able to spin it or not? The far has no motor so I can't test it by driving it.

Any help much appreciated!

Usually new/tight LSD's take a medium amount of force to rotate a wheel while your assistant holds the other wheel steady. I know it's stupid but is the gearbox in neutral and/or tailshaft not binding up on the body for some reason? (you did say no motor in the car). IIRC it should take 50ft/lb of torque minimum to rotate one axle while the other is held stationary.

Well it has no gearbox or tailshaft either lol so when I spin the wheel it is purly the diff rotating nothing else

leave one wheel on the ground and jack the other one up off the ground. If you can stick a few fingers thru the wheel (off the ground) and turn it easily then your LSD has weak preload or is shagged

if it takes a fair old push or two hands to turn it then it's still tight

Yeah it does take a fair old push to turn it, it's definately not easy
