How to tell if car has LSD

Something wierd has came up. I have heard that if you lift your car and spin one tire the other tire will go the opposite way, this indicates if you have lsd. My car doesnt do that but my friends 96 max does. Does this mean he has LSD?

The last (or second to last, I can't remember) letter in the transmission code will be a V if you do have lsd. If it's an A, you do not have an lsd transmission. I don't think any 4th gen had them though.

no 4th gen had LSD from the factory on the US, so chances are you have an open diff.

where the wheel with the least traction gets most power and just spins. the car doesnt accelerate as much as it could because power is being lost. take a corner really hard and floor it, the inside wheel will spin like crazy and we all know traction is key.

If lsd, both wheels should rotate the SAME way. If it rotates the opposite way the viscous coupling is damaged.

Look at the tranny code. If it ends in V, lsd. If it is A, non lsd.

VLSD is definitly superior to a clutch-pack LSD. If those stillen clutch pack lsd's are junk and the vlsd's are even more junk what's better?

vitek/phantom grip IS crap but the actual real deal vlsd is NOT. The only thing that is better is helical lsd.

How sure are you about that? I thought mine rotated opposite immediately after my rebuild but I'd need to check agin.

They should turn the same direction. Thats what the fsm says. Remember, if you dont have a vlsd, then you dont even have the viscous couplings and dont need to worry about this.

For us, they rotate the same. Some cars have a clutch style lsd which will turn opposite if you just jack the end up and spin one of the tires, so it depends which what type of lsd. If you have a vlsd on this car they should rotate the same.

I said the the vitek one was even worse than the vlsd. I didnt say the vlsd was worse than the vitek.

Devin is correct about this as usual.

Maybe it's car-specific as far as what's offered, but right now the guys autoxing their miatas prefer Clutch-type = Torsen >>> Viscous for performance duty. It's partially because the Viscous was a much weaker rear end in stock form, but even then the aftermarket sticks to the former two of the three options.

The Torsen that's in those cars just multiplies the maximum torque to one wheel by up to ~2.5x on the other - a very gentle setup - so if one wheel is caught in a low traction situation or leaves the ground, you apply little or no power to either wheel. Maybe it's a RWD thing though, I'm still trying to mentally sort through how these things would affect a FWD car's driving.

The clutch pack type LSD will react to wheelspin much quicker than a viscous-type LSD. I would say that's better... in regards to the quality of a particular product, possibly not, but in concept a clutch pack LSD is "better" than a VLSD, at least for RWD applications. Now that I think about it, FWD may be another story, since it ideally will need different turning speeds of either axle.
