Anyone out there experienced any faults with the rear limited slip diff in the new 70 series Landcruisers.
I have a 2007 70 series ute and I have noticed that the limited slip diff does not function as I believe it should. Pulled up on the side of the road today, two wheels on the gravel & the other two on wet grass, slight uphill grade.
When I tried to start off the L/R wheel which was on the grass broke traction, & I didn't go anywhere, just wheel spin on that wheel. Had to engage front hubs & 4wd to get back onto the road. To me this does not seem right as I have a Nissan Patrol that will go in the same
places in 2wd & stopping & starting is not a problem.
Any thoughts would be appreciated as the ute is still under warranty & if it is a diff problem I would like to get it sorted before the warranty expires.

The simple answer is that the Toyota LSD does not last very long, say about 40k k's. Our 80 series rear LSD suffers from the same fate.
I hate to say it but the Patrol's LSD is a beauty and seems to go in excess of 200k k's.
I did see a link to a fix for the Tojo's and it was to sandblast the friction faces.
MM me if you would like a contact for the work.

the LSD in my 100 series was useless at less than 3k, it may
well have been an open diff as thats wen i installed lockers- brilliant.

That sounds about right,
mine has done 38000km and I have had suspicions about the LSD for quite a while.
On the other hand the old Nissan
farm ute has done in excess of 300000km and the LSD seems to still work as good or better than it did when new.

A little trick with LSDs is to pull on a little bit of handbrake, works on my Jack but not sure about the useless toyo LSDs

Well - When you pay that much for a car you would expect that option to work.
If it does not, how about a refund of the cost of supplying that option to start with?
My Rodeo is still good with 75k on the clock, but with the situation you were in (and in my country it is often), I find if you put it in 4 low with the front hubs still disengaged and then give it a go, the lower gear speed enables the LSD to work a lot better without the wheel spin. Let the car walk itself as more gas = more spin.

When I bought the trayback last year LSD was standard at the back. Factory locking diffs were the optional extra.
I have not got much of an opinion of
mine one way or the other. One day if when I start doing
rock climbing I may get air lockers or something.

Flynnie - :-) Sure you were replying to my thread?
My suggestion was to get full use out of the LSD was to put it in 4 low without locking the front hubs. That way you are driving low gears to the back diff.
By doing this the back LSD works a lot better as you are not applying too much power and overriding the LSD.
I do this for towing the boat up the ramp or on my slippery lawns - no hassle of going into full 4 x 4 but gain the benefit of low gear to the LSD.
I think if all the cruiser owners try this that say their LSD no longer works may get a pleasant surprise. Maybe they just give it too much power and thus the LSD Slips as designed.

It was a reply to your first couple of lines "

LSD is a standard fit or was - not an extra cost option. This is only a small point I admit. I might have been being a little pedantic.
I will give your suggestion of using low range without hubs engaged a try.

re-reading this made me think about other LSDs i have had, this one in a VK Calais, not the worlds strongest diff but it was still fairly tight after 200k. then i increased is power output 4 fold( injected stroker 5ltr) and found it would intermittantly only leave 1 patch, sometimes 2. someone suggested try a LSD treatment so i bought the Penrite one in a little bottle( maybe 50ml if your lucky!) and i tell you what, the longer and harder i drove it the better it got. always 2 patches left no matter how hard i accellerated,turning corners slowly the inside wheel chattered as if it had a locker in it( which i did fit later on) but that stuff did work. never thought to try that on the 80
