Anti-Spin Diff Story
I have some thoughts to share about the value of reading and participating in this forum.
I ordered my truck with an "anti spin" or "Limited Slip " differential as I though it would be of some value in off road situations. Yesterday, at the summer cabin, I parked along the side of a road, putting the two curbside tires partially in a shallow ditch so I wouldn't be parked completely on a narrow roadway. I realized too late that the ditch was very wet. The right side of the vehicle sunk down (not to the axles, though) and I found both right side tires spinning, with the truck only able to rock a foot or so in either direction. The left wheels of the vehicle were on a gravel shoulder, but I wasn't able to back out of the ditch.
Not wanting to dig a 2' trench trying to rock the truck, I considered calling for a tow truck (an inconvenience, to say the least). My girlfriend couldn't believe I was stuck. I was scratching my head wondering how it was that the vehicle was stuck with the left rear wheel sitting on a gravel. It was at this point a though of what I had read here popped into my head ... something about needing to apply the brakes, or the parking brake to help engage the anti spin feature. I tried it and the truck walked out of the ditch without any fuss (or muss).
We ended up going Sea Doo-ing instead of waiting for a tow truck. Thanks to those who contribute knowledge to this forum. Hopefully I can return the favor some day with my own discovery.

I remeber reading that now. i wish I would have remembered that the other nite. I was at a tractor pull and had to park in a deep ditch because the lot was full. I drove down in and went to do a left turn so as to be parked facing directly up out of the ditch and I couldent get turned. One tire kept spinning and i thought to myself what happened to my limited slip? Now I feel like a dumb poop.

Remember moderate pressure. I don't know it you could break a dana 70 or 80 axle with the brakes but it happens alot with smaller axles. If you really want it to work and can deal with the driving quirks get a detroit!

In your owners manual you will find referance to partially applying brakes to help engage anti-spin.
BTW, lightly applying parking brake will sometimes help even with an open axle.

I guess i will have to try that with my 2WD. It seems like my anti-spin is making it worse when I try to take off in mud or snow, especially if I am trying to turn at that time. Kind of like one wheel is dragging the other (which it probably is).

Gotta be tough for those guys with manuals to do the brake trick thingy, unless the parking brake deal really works. Luckily, I haven't got stuck yet to try either method. BTW, is anyone else having a problem with the rear diff cover paint peeling off and rusting in only 7 months (12,500mi.)? Was wondering if maybe it's getting too hot and blistering the paint. Dealer said, that's right, you guessed it, "that's normal, they all do that". I told him I don't buy it, so he's ordering a replacement. Sorry, didn't mean to hijack the thread, just talking about the rear reminded me of this problem.

Quick note:
Manuals can take off with out touching the accelerator pedal; the comp adds fuel for you.

Maybe me diff is just unusually tight from the factory but when I want to spin the tires both of them spin. Proved it this past weekend pulling a chevy and a ford out of the dunes at the beach.

The rust on mine is directly under the ball for the gooseneck.It comes on goes.It does wash off at least on mine anyway.My antispin has worked fine in mud and wet grass with trailer hooked.It also has worked fine the few times in the rain I cut it loose and went down the road sideways for a short distance(on purpose)

Sticky, My rear cover peeled and rusted around the same time frame. I brushed it and sprayed it with undercoating.....It's still bleeding through though.

I have a manual and when I get into a wheel slip situation I use first gear, let out the clutch at idle and let the wheel spin while I move my left foot to the brake. As soon as I touch the brake the truck starts to move. Then I add more throttle.
