Anti splip differntial issue/ question

[Jim Smith]

Help, I was taking my jet ski out of the water at the boat launch and got stuck in the the soft sand. When trying to get out my son said only one wheel , the right one is spinning. My question why not both wheels?? Is there something wrong with the differential ? Thanks , Jim

My limited slips sucks too. I got stuck on the wet grass the other day in 4wd. One back tire and one front tire spinning. If you apply some brake force or set the e-brake lightly you can get a little resistance on the spinning tire side and sometimes it will force some power over to the stationary side.

No yours is working the way it is designed to. It needs some load on both wheels to work. If one wheel is spinning to freely it won't engage.



On yours if you jack up both rear wheels and spin one in one direction the other side will spin the opposite way just like an open diff.



Give it some brake to slow the spinning wheel to put a load (or in other words equalize the bias) on the differential and it will start engaging and provide torque to both sides.



Your differential doesn't work like the older ones with clutch packs. This technique also works on the older clutch types also especially if they are loose.

Exactly correct Gene. I've been in some muddy conditions and my buddies were telling me my limited slip wasn't working and dissing my truck. I touched the brakes and both started digging. Shut em up fast when it walked out of the mud.

It's also totally useless on ice and snow. touching the brakes did NOT work in that instance.

The Brake trick has never worked for me either

As far as I can see the only way that would work is if you could put more brake pressure on the one that is spinning.

If you apply the brakes, it applys pressure to both wheels equally.

so you end up with the same situation only taking more power to spin it.

Works great in snow, ice, mud, etc, if you have a tire that has traction. Its not going anywhere when both tires are on slick surfaces.



The idea is not to overpower it so much one wheel is spinning out of control. That will allow the light braking action let the brake shoes in the LS apply some friction to stop the spinning and shift the power.



Some of these LS's work great and others are no better than an open diff. More than likely activators are jammed on their slides and simply won't apply. If it doesn't work a tear down is in order to find the bind and fix it. These systems work great on slick roads and with the extra weight up front they are amazingly stable on roads a person would be hard pressed to stand on.
