L/S wear question

So I know this depends heavily on the driving style on the user but when do LSDs usually start to wear? ie, when do I need to rebuild it?

When it breaks?

I never rebuilt mine and it had over 100,000 on it and it still running for the current owner with over 125,000 on it.

Well no **** when it breaks but when the clutch disks start to wear the one wheel gets less and less power over time right?

75-100k

You will feel it be less effective. If you wait to long they can go boom. Seen it twice where the clutch pack comes apart and locks up the rear.

Yeah 70k-100k sounds about right. I took mine out at about 105k and it was useless

Well the rear end I bought has around 140k on it. The L/S feels like it still works fine though? Just driven easier then most or am I crazy?

You're not crazy . Mine has 158K and still works fine.
Just change the fluid every couple-three years , unless you're running non-stock oversize tires.

If you are on the gas even a little bit in corners it will wear them pretty quick. Or if you see a lot of slippery weather and still mash the gas, that will wear it too.

Ok well I have the the service manual and it says don't change the fluid unless it gets submerged because it's full synthetic. And as far as turns I have a stick so I'm shifting on a turn anyways so looks like im set.

Nope, it's very possible. Go with a gear driven limited slip if you ever replace it.

Must be a NY thing that they last long there.

Thanks Blhde. That actually looks easy... I just don't know how bad/if my LSD is bad since I have nothing to compare it too.
