limitid slip diff

I noticed that I only have one wheel spinning when I did a burnout this morning. Does this mean that the clutches in the diff are bad? If so how hard are they to change out

Are you sure it's a limited slip differential?

I dream of a better tomorrow, where chickens can cross the road and not be questioned about their motives.

sometimes only one spins if it has substantially less traction. Limited slip is just that-LIMITED SLIP-meaning it can slip.

If you're in the dirt and you peg it, does the truck go sideways? I'd think your clutches are getting worn, but changing them isn't easy.

With a limited slip expect to see the wheel with the best traction get the energy sent to it.

How many miles are on your truck, and when was the last time you replaced the rear diff fluid? If you have alot of miles maybe a fluid change would help.

And if you really need both wheels to spin, power break it a little, that should trick the LS and get both wheels spinning. I have not tried in a Ford yet, but this worked in my old Dodge. Good luck!

I was going around a corner and the inside wheel was spinning. My truck has 94,000 on it.

My 03 does the same thing. No posi going right but it has posi going left so I can fish tail. When I brake torque it I only have one wheel peel too. Next time I am going to get on it and let off then get back on it to see if it might fool it.

I think the Ford Trac Loc is a fairly "weak" posi. Mine does pretty much nothing...ever. But Im also pretty sure that my clutchs are worn out, I can get some vibration on long corners wich is supposed to be a sign of the clutches failing
