Ok, not the greatest of headings but I couldn,t resist.
My story is as follows.
After reading the post 15063 I tried a few thing with my 4WD in relation to LSD.
I wanted to find out if my LSD is Stuffed or not.
For those of you concerned about safety do not read on.
I jacked up one side of the back diff of the 4WD with a trolley jack. Put the car in first gear and tried to drive off. I went nowhere fast. So I thought I would try hitting the brakes to slow down the tyre and see if that would work. Nope no luck there either.
Now for the handbrake, Salvation at last. The car was trying to drive off on only the one back wheel. I could not believe it. Now obviously I didn't(Aandy?) try to push my luck so as soon as I felt the car wanting to move I stopped and took it off the trolley jack.
Now I would like to know if this is common knowledge or just a stupid way of testing my LSD.

Sparkie,
Found this in a Google Search
The HMMVV, or Hummer, uses Torsen® differentials on the front and rear axles. The owner's manual for the Hummer proposes a novel solution to the problem of one wheel coming off the ground: Apply the brakes. By applying the brakes, torque is applied to the wheel that is in the air, and then five times that torque can go to the wheel with good traction.
Is this what happened with the handbrake?? This was in a site How Things Work or sometheing like that.
Cheers
Magnus

I tried with the brakes but it didn't seem to work. I assume it was because the front brakes were applied as
well as the back brakes.
I tried it tonight with my brothers GQ patrol and his did the same thing except his LSD cut in by just putting it in first gear.
not enough to move it but substansial(spelling?). When applying the handbrake it really wanted to move.
Now I am not saying it is the correct way of doing things but it seems to me that if you are stuck wit one front and one back wheel in the air you have an option of engaging your LSD to help you get out of trouble.
What I need to know is if this is common knowledge ???????
