Which models had LSD?

Anonymous · April 8, 2009, 14:17

I have had a search on google and on the forums but I can't quite work out which cars have the LSD and what sort of LSD it is.

I think the following is correct:

All post-facelift UK cars have an LSD, all pre-facelift UK cars don't.

JDM models had an LSD as an option, which can be determined from the VIN plate under the transmission section. A denotes no LSD, B denotes LSD.

Is this correct?

Thanks

That was what I wasn't sure about to be honset. I wasn't sure if it was just the 6-speed boxes that had them.

All UK cars, regardless of year, have an LSD

Great, that's good to know! What type is it? E.g. Torsen, viscous etc.

Toyota only used one type in the production gearboxes - it's a helical diff.

I think there is a TRD branded aftermarket part that's a clutch diff, as well as an aftermarket helical from another company.. I think - I didn't look into it that much, the helical does me fine s:)

Not to dispell your thoery. s:flame: :flame: s:flame: I have a 2000 5 speed uk model, and having parked with one wheel on the grass verge and one on tarmac, subsequently "floored" the car the inner wheel on the grass just sat and spun s:scared: :scared: s:scared:

I assume this is the normal test to confirm if an lsd is fitted

Ah, Helical diffs don't work like that, they are torque multipliers, not locking diffs. Essentially, they multiply the torque transmitted by the faster turning wheel by a value set by the manufacturer, and transmit it to the slower turning wheel. So, if you have no torque at the spinning wheel, you will have no torque at the slower wheel. Torsen/helical diffs are designed to promote cornering stability and increased drive on the road.
