Hey, it seems the limited slip rear on my new F250 superduty pickup doesn't work. Anyone hear any rumors about putting the wrong rear in, or malfunctioning posi's.
Thanks,
Pete

ford posi's are know for not working,the spider gears in the posi unit go bad.
you can probably get it rebuilt or if you dont mind spending a few extra bucks buy a better aftermarkt one.

The truck is brand new, 1,700 miles. Maybe I'm asking too much, but I assume if I'm in loose dirt or stones, I should be able to turn over boths, and not have one just turn, correct??? I assumming this should like a chevy posi-rear from a street machine type car.

I am not sure what kind of limited slip Ford is using but if it is a clutch style unit then it may have been put together to "loose". If I am not mistaken with that style posi you can add or move the clutch discs around to tighten up the unit.

Pete,does your window sticker say TRAC-LOC,if not ,your truck doesn't have "LIMITED SLIP" It just has an "open carrior". Trac-loc is a pretty good unit,its no ARB,or detroit locker,or even an auburn,but it is much more user friendly.-

dude, bring it back to the dealer for sure man.
i would have them fix it, i dont think they should give u a problem with such a low milage.

Thanks everyone. My only concern is I hope the dealership is "up to" fixing a rearend problem, and not make it worse

rear ends are pretty straight forward and not too complicated, its part of basic auto repair, the only difference is your treuck has a physically bigger rear end, so u shouldnt have a problem.
