So whats yer axle code?

If you have a limited slip, it could be the friction material in the discs has erroded away and now its time for replacement.

If you have an open diff, then it could be the spider gears and side gears are worn from lack of lubricant because one tire is spinning faster than the other constantly (two different sized tires on the same axle). It could also possibly be a cracked or broken spider gear causing undue torque on the other gear causing the noise..

Just my $0.02

Dear Ford Tech, Thanks for the resonse.Where is the axle code?Both tires are the same size.Is there any way to verify this stuff about the spider gears without a tear down?If I did need to replace these gears, what would be the best course of action, Junkyard?Or are there Ford or aftermarket parts that would do it.Thanks

Freudian slip?;-)

No, just a joke. I heard a guy at a body shop use this term once, and ever since then I have used it too.I used it here because I thought it would have been seen before on RAF

Reid,

Axle code is a two digit code on your certification label on the drivers door pillar. Its in the very bottom row, and has AX CODE above it. Its on pg

12 of the document below..

Should be an D something or 4 something code. D something is the code for limited slip and 4 something is an open diff... Check out this website it explains all the axle codes. Scroll down to middle of page.

Happy Hunting.. Ford Tech

On low speed turns... if it's limited slip ..FIRST add half bottle of Ford Friction modifier.

That was a just a good natured poke at a fellow that I haven't seen here in a while. Heed the advice. The friction modifier will likely work. Backyard is a smart cookie, just don't let him know. It'll go to his head. ;)

Hey BY, where ya been? I haven't seen you post here in a while. I hope all is well with you and yours.
