I have an 08' F350 PSD 4x4 with limited slip... I was playing in the sand today and the right rear wheel spins in a light sand area on the side of the road. Right rear wheel on sand, left rear wheel on pavement (in 2 wheel drive). Does any one know what the bias is set at or suppose to be? Is the limited slip a weak unit or is it supposed to kick in hard and spin both rear wheels or what?

Thanks...

 

i have heard some people complain that the limited slip was not working on their trucks and i believe to resolve this is more friction modifier or change the clutch packs in the rear end. Most of the people i have seen this happen to are Job 1 trucks and i have not heard from the job 2 trucks

 

Thanks for the info Red Dragon, I have a build Job #1 truck (built 7-11-07), I agree with modifier or clutch packs, I might try to do a couple of figure "8"'s before I look at friction modifier...

 

I took my truck to dealer for this problem. They tightened the unit up but I still feel the unit is very loose.
The dealer says Ford sets the rear end up very loose so people will not compain of chatter around corners.

 

The dealer repacked mine under warrenty it is fine now can't make only one wheel spin
to bad everything else is going wrong!

 

hey Tom i still think the dealership sold you a Lemon man, I know the guidelines say no legal advice but i can say Call Ford Customer Care and complain till they get you a new truck

 

Thanks Man! I did call they are going to call me back tomorrow
