Trouble with my torsen

Hi i have a level II 03 and since ive had the truck ive never felt the torsen lsd do is work. Ive changed the fluid last year cause the pignon and axles seal where leaking looked at it everything seem ok but i always have one wheel spin with no change. Last night i had to go in the snow bank with the truck and the left rear wheel was on ice it never transfert its power to the right i had to remove the snow around the right wheels to get out even with the right wheel at 12pis. Am i missing something or what. Once at work i had the truck on the lift and both wheel where lock together i had to spin a couple of time one wheel in both direction to release it.

Uh??? You talkin about lockers? One wheel is going to spin unless you have lockers or a good l/s. If your driving your truck your t-bars are working.

how many miles/km you have on it? ford torsion diffs are prone to wearing out because its a ford part. every once and a while mine wont hook up and ill get one wheel peels

hmm sounds to me like you think your torsen is a locker, which it is not. The operation you explain sounds normal for the torsen diff.

Its suppose to tranfert the torque on the wheel with the most grip but it doesnt i can spin a rear wheel on ice has long has i want. the truck has 60 000 mile on it. I bought the truck use and i did a big mistake i should have bought it brand new it would have cost me nearly the same thing if i consider how many reparation i have done to it since i have it

Like I said, the operation you describe sounds normal. There is a point when the limited slip torsen effectively becomes an open differential and that point usually comes in low traction situations. The lower the traction, the harder it will be to keep the unit from slipping. If you want to avoid situations like this then ditch the torsen in favor of a locker.

get rid of that pile of crap Torsen. They're crap. Had mine blow up on me back in November. Threw a TracLoc LSD in, works like a charm.

I am not sure what you mean by the wheels were locked together but that sounds more like a locker than a Torsen. Your explaination could also happen with a Torsen due to the gears in it needing force to get them to start working to get the rotation of each wheel to be different.

The Torsen differential is basically a limited slip differential and other than a few properties unique to the Torsen it acts like a LSD. If you have one wheel on ice, a LSD does not guaranty that you will not get one wheel spin. Yes, it transfers torque to the opposite wheel but if the slipping wheel accepts no torque there is no torque to transfer. Lightly applying the parking brake helps in a situation like that.

I have over 80,000 miles on my Torsen, much of it off-road, and it still works as well as it did when I bought it new. One of the advantages of a Torsen is there are no clutches to wear and it remains functional longer. Any mechanism like that can have problems but overall they work well. They are not magic but are not a plie of crap either.

If you want both wheels to spin when one does not have traction, then you need some type of locker.

Ive tried many car with clutch type lsd and they all worked better then the torsen. Even my old s-10 with the ratchet lsd diff worked better even with the clutch worn down. Ill try to find someone in my area with a ranger that has a torsen and go for a roadtest see if its different then mine if not then ill live with it.
