I have a 1993 Ford F150 4 wheel drive. I have the numbers from the rear axle, but I get conflicting answers on whether this is a limited slip differential. The numbers are:
355 882 L03
Does anyone know whether this is limited slip? Thanks.
1. Look on your driver's side door jamb--under "axle" you should have a code like "H9N" which would tell you that the factory stuffed a 3.55 Traction-Loc under there, and/or:
2. Jack up the rear end so both tires are off the ground. Rotate one wheel by hand--if the opposite wheel turns the same amount, you, sir, have a traction aiding device of some sort.
FWIW, if you're interested in Ford's breakaway spec, it is 50 ft./lbs. To check, raise one wheel off the ground, set your torque wrench at 50 ft./lbs., and turn the raised wheel by one of the lug nuts. Ford sez to do this with a special tool which poitions a turning hex directly concentric with the axle center, but...

If your knuckles ain't bleeding you did something wrong.

for a long time i thought i had a limited slip rearend because of that tag on the pumkin. but one day an unwise and unlearned person said to me (take a leak now cause you might wet your pants laughin) that fords suck. i skooled his ##### on that one by doing a brakestand to make his mother cry. but, twards the end only my pass. tire was spinning? what's the deal?
I know this is an old post, but I just bought a 2001 with the 3.55LS, Axle code Is the H9, and the diff take does say LS, But when I make hard left or right turns froma stop, I get the chattering. I had Ford do both rear seals(cause warranty paid) and they did put the modifier in. How long does it take for the modifier to "work" its way in? I looked in the case when they had it open and I didn't see any packs. Are they hard to see? Ford tells me they won't replace them either, because its not a "Safety" issue, sO I was going to do them myself iif need be.
