I was out over the weekend and found a great spot to test the LSD. There were two deep pits at front drivers side tire and rear passenger tire. I had a friend drive up into this and the rear passenger tire was spinning while the rear drivers side was not. I guess this means the LSD was not working very well? The rear passenger was completely off the ground. I got in and pulled the e-brake pretty hard while giving it some gas and popped right over several times. The difference between using the e-brake and not using it was significant. Is this normal behavior? Could my LSD be worn out?

I also noticed (on some much steeper more difficult terrain) that my front wheels were both stationary while both my rear wheels were spinning in loose dirt while in 4wd. Is this possible?

thanks,

Funny-

I was changing shocks last night, and thought
'I wonder if I can break the LSD loose by hand'

It's not easy, but I can beat the lsd by just giving the wheel a good twist. Not too impressive, really.

So I'm thinking we both need to pop the pun'kin and shim 'em up...

i can't break mine by hand... that why I dont understand why it was slipping. I did have it in 4lo which maybe creates so much torque that it instantly overpowers the LSD. Is it as simple as shimming to make it work better?

Remember, this is not a locker. You can defeat a new one by hand as well. I found that my LSD works real well when I am moving but once I get bound up and stopped. I'm done, time to reevaluate where I'm going and how I'm getting there (backup <img src="/forums/images/graemlins/wink.gif" alt="" />). I frequently end up on 3 wheels, sometimes two <img src="/forums/images/graemlins/rolleyes.gif" alt="" />. LSD clutches only have apprx 60lbs of preload on them. <img src="/forums/images/graemlins/kewl.gif" alt="" />

hmm... maybe it's time to think locker. The e-brake REALLY worked well though. As soon as I yanked that thing I popped right out of the hole. Hate to add all the complexity of a compressor and all that other stuff to break though. Now that I know the e-brake works so well I'll have to try that more often... maybe I could separate my e-brake into left and right. No e-brake for the front if I were to go LSD front though <img src="/forums/images/graemlins/frown.gif" alt="" />

Thats where the brake pedal helps Its like an E brake for all four wheels <img src="/forums/images/graemlins/smile.gif" alt="" /> .... Though with a stick it can be hard to manipulate the clutch, brake and throttle!

I was gonna change my fluid this weekend after the trip I took, but nobody seems to have the rear diff gasket. I haven't called NAPA tho so maybe they will be the one. My LSD worked in a seemingly excellent manner. It was the reason I made it up a steep and muddy hill, but I managed to not get a pick of me doing that <img src="/forums/images/graemlins/shiner.gif" alt="" />

gasket? i just used the orange stuff. Hasn't leaked a drop

I cleaned both sides with acetone, and let it get a little tacky for about 5-10 minutes then squished it all together. I still can't believe it actually worked but I didnt' know there was a gasket available.

Gasket??? Maybe I'm missing something. I just drop my Plug and drain the gear oil and refill to the upper fill hole. I don't pull the 3rd member unless theres a problem. As goes for the ft diff cover, I just pull the plug and refill to the upper fill hole. I do this very often so my fluid comes out as clean as it goes in. So what gasket are you talking about?

My LSD works a little better since I stopped using the friction modifier additive.

Whenever I'm in a low traction situation I always think of it like this:
The static coefficient of friction is larger than the kinetic coefficient of friction.

A spinning tire has less traction than a non-spinning one...
OR
A slipping LSD has less friction than a non-slipping one.

Basically this boils down to trying not to break your tires loose in the first place. <img src="/forums/images/graemlins/wink.gif" alt="" />
