LSD problem please help

An LSD is a "torque biassing" device. It depends on there being torque on both wheels ie both wheels have to have resistance ie be on the ground. Where one wheel spins the torque is biassed to the other wheel up to a set % usually 30% .

If one wheel is off the ground the LSD will not send torque to the other wheel.
I am talking about conventiuonal LSDs here . There are others that work differently. The test was not really valid. A better test would be to put one wheel on grass and the other on bitumin and see if you can pull away briskly.
BTW many people claim Toyota LSDs quickly wear out and need rebuilding after a low mileage.

You dont have a problem, Toyota LSD are one of the poorest on the market.

The only thing you can do is regularly change the oil using good quality LSD oil.

Jared,
I have a '96 hilux aswell. I bought it second hand with 55,000km on it 11 years ago, the owner said it did very little off road work.
I was at a mates place who lived on a very steep block of land. I tried driving up the grassy slope and just one wheel was spinning. Hilux LSD's are hopeless. I replaced it with a Detroit Trutrac LSD. Works a treat after 340,000km and still going strong. When i got mine it was $900 fitted.

Thanks for all the help!! Much Appreciated

seems like one side is worn more than the other, as a mechanic the way we norm test them is to have them in the air, and rotate the axle, both should turn in the same direction, from etheir side, from what ur describing id say that one side is worn, left normally wear first due to cornering, and wheel spin being generally more to that side.

Good to hear that you have the problem sorted out, an extra shim will place a bigger load on the thrust plates so increasing the torque required to allow the wheel to slip.
In regards to toyota LSD being weak, I Have just my diff reraced and the LSD wear components replaced, mine is a 62 series, 21 years young with 520000k's on the clock. Yes I do go bush,

I left the diff centre with the repairer, he rang me later to tell me that you couldn't find the cause of the whine and that he didn't know what i was chasing, I thanked him and let him know that i was overhauling the diff purely on mileage not because there was a problem. Total cost $550.00
Anyway i am off to Tassie for a month in three weeks, then a slow 2 week trip from Melbourne to Taree.
Regards
