Well I decided it was time to change my rear diff fluid.

And look what I found.



I think its a shim but what does everyone else think it is?

Either a shim or a piece of a seal

Glad my truck and chip only can't turn my tires. Can't afford to be doing that.:doh:

I should probably do mine. I don't think it's ever been done. How often are you supposed to?

LOL get ya some injectors and some new tunes and ya could.

Ford says since its synthetic that it don't need to be changed :doh:

This is the 1st I have done mine and i probably should have done it sooner. I think im going to start doing it every 50k with the tranny and t-case fluid

I've dropped enough coin on my truck this year.:ford:

I might have to look into some different diff covers. Did you change the front also?

That appears to be a metal "chip" produced during the machining of the axle tubes or third member.God knows I have seen enough of them, I have been in the contract machining business for 33 years. It could still however be a remnant of a seal, but I would expect to see at least some rubber adhering to it somewhere.

It looks like a pinion shim.... do yourself a favor and unbolt the drive shaft from the pinion housing and check the pinion for in and out play. I found the same thing when I changed mine and the rear only lasted bout 500 more miles then ate up the pinion bearings.

and if your rear end blows its cheaper to buy a rear axle than take it to a shop to do it. Unless you know how to do it yourself.

If mine blows. It would be time to figure out how to do it myself.

I learned how to rebuild a motor right after I blew one up.

:whs: No pun intended but if something does happen what an excuse for a Tru-Trac or other simular upgrade. :D

Before you did that, you would have to replace the ring and pinion gears. That's the hard part of a rear differential. The rest is easy.
