I have a 2000 F350, 7.3, 4R100 and probably a 10.5 rear end.
After checking fluids today I got this!!!
Where did this come from?
Was on the magnet fill plug for rear diff. Concave and as is it will be about 2 inch OD.
I'm guessing it's a carrier shim. I wouldn't be too concerned just yet, they're thin (sometimes a few thou which is, well, literally paper thin) and can break off if hammered in incorrectly, ie proud of thicker shims that can take the beating.
Yukon even markets radiused drivers for this purpose.
If you're so inclined pull the diff cover and have a look. You'll need to pull the carrier bearing caps so have a torque wrench to reinstall.
But if the rear end is not making any noise....ignorance is bliss!
Thickness .03 and 3/16 wide.
My guess was thrust washer in spider gear maybe...
Rear end not been open for 300000 miles, but always had oil in it.
So when I'm going to open it I like to have the parts I need to finish the job.
Might be time for aftermarket diff cover, any recommendations?
I’m a fan of the ribbed covers. Found this one online. Identical to the Ford, less the Ford logo. Painted it gold. SS hardware. Be sure to use the correct caulking that is compatible with the oil if using caulking.
I would not run the axle without replacing the shim. Part of that broken shim could get into the ring and pinion or cluster gears set and destroy them. Running with even an additional 1/1000 of an inch of play can dramatically shorten the life of the gears and bearings.
Read up on the correct way to do it! At the very least you must mark the retaining clamps and keep them and the shims for each side separate and reassemble them exactly as they came out. You should also measure rotational torque, gear lash and the contact pattern and reassemble as close to the orriginal settings as possible.
There are many write ups on this forum and others and videos on YouTube on the correct procedures. Spend some time studying and save yourself hundreds of dollars!
Ok, so I found where the piece came from, but I can't find a parts diagram or a part number.
Totally disappointed I don't have the limit slip diff on my 4x4 as a "friend" pointed out and said it was the belleville washer.
Yes for sure, the factory limited slip isn't that good so it's no big loss that you don't have one. The Truetrack is far better.
Not only isn't that good but most aren't doing anything within a couple years. AFAIC a TracLok is an open diff and no way I'd willingly pay for one if given the option when ordering a new vehicle

Airflow under a vehicle is about 50% of the vehicle's speed. Banks did a real test of the cooling characteristics of the finned diff covers and found they do very little in the way of cooling, and some actually changed the oil flow in the diff so that it was not as effective as the stock cover. Banks then designed a finned diff cover that scoops in the air from each side of the diff and directs the airflow over the fins. His tests showed this one to be effective at actually lowering diff temperatures. Unfortunately, this is a fairly expensive diff cover. There are several videos on this, here is just 1 from a list of many
Oh god not Gale Banks's garbage again. I am tired of hearing about that overpriced, ridiculous designed cover that hangs down below the differential so it can catch on something and get ripped off, can't believe people still fall for his marketing scams.

I am not promoting the Banks cover, nor am I interested in purchasing the overpriced cover, but you need to look at the product before you start making false claims about it. It doe not sit any lower than the factory diff so that it can not drag or snag on things. Now it is wider as the vents are on the lower outer edges giving it a squared off look. I believe if you do drag the diff over something, it will present a wider area for contact and possible damage, but it in no way reduces the normal ground clearance of the diff to ground.

"Marketing Scams"
Actual tangible, measurable, duplicatable proof. Sure the design with the thing scooping air from underneath is not ideal for rock crawlers and the like but unlike all of the aftermarket junk it actually does what it is supposed to do. Most folks are using their trucks as grocery getters anyway, most of the people hauling heavy that would actually see any benefit from a fancy diff cover will never be found roaming around in the rocks because their trucks are on the road making them money.

Did you even watch the videos? The differential temps didn't get too high with any of the covers he tested except for one test where they had it under too much load for too long and all of them overheated. Once again marketing a product to solve a non existant problem. I rebuild axles and I have never seen one get too hot from running an aftermarket or factory style cover. As long as your axle is full of clean gear oil and you are not towing far beyond the weight you should be towing with a pickup your chances of axle failure from overheating are extremely low, no matter what cover you use.
