3.55's or not?
I have a 91' F150 4X4 and the rear end has 3.55 gaers,I need to replace them. I can't find any rear ends at junk yards,I was woundering if I could use the gears from the front axels of the same truck? Would they be 3.55's or not?

Summit and jegs sells them for around $185. There's a buddy of mine on e-bay (look for the guy that lives in Carthage, NC) that sells used (like new - less than 10k miles on 'em) for around $60. I've got a set of his 3.73's in my f150 and they're great...no noise whatsoever.

If no one has said it yet, Welcome to FTE!!
Just for future info, your front diff gears are the reverse rotation kind just the oposite of the rear and are not interchangeable. The would also be 354's as most of the front gear ratios will be -.01 less than the rear so the front will pull through the corners and not be pushed.
I would check the ring and pinion over real carefully as those spiders could have sent metal through them and nicked them up. You might as well replace the bearings at this point as they may have had metal go through them as well. Do you have traction lock? You might look into adding it if you dont.

Thanks for the welcom! I'm not sure if it is the traction-lock,but I think it is,It has what looks like a clutch pack on the passenger-side axel and a black C style clamp/lock in the middle(between sider-gears)the tag I took off the diff. cover reads
top line:s837a bottom left:3L55 bottom right:880k05,the L in-between the gear ratio might mean locker? don't know?more help would be very much aprechiated! Thanks for all the info. Trying to get all the nallage I can!
