GEN 1 Rear differential thrust washer

Well of course you don’t. Your shop that you trusted to do your work ****** you. Take it back explain the situation and make them assemble it before you end up with more metal wearing out asap. It’s a no brainer,and for us to sit here and argue back and forth is a waste of time. If you insist on calling our bluff here fine. Expect another rebuild in a year or less. Just because you don’t see how or know how that can happen doesn’t mean it didn’t.

Oh not arguing that’s it’s necessary at all. If it was intended to be there from the factory then I agree it needs to be put back. Certainly going to have them inspect and reinstall properly. Wasn’t looking to leave it out.

Was just trying to understand how it could be dislodged during a simple axle seal job. That was all.

Anyone have a thread or video of the 9.75” E-locker differential tear down?

It is #4 in the diagram. When they slid the pin out and removed the axles they must have unnecessarily spun the spider gears out. They are a pain to get back in but definitely shouldn't have just been left in the bottom of the diff housing.

It's easier than you think for that to fall out. If they turned an axle any time that the pin was out it could walk the pinion gears and washers out. The only time those gears turn is when the rear tires turn at different speeds like in a turn or when your stuck with only one tire turning. So without that washer in there it allows a little less contact between the gears and over a long period of time may wear the case. If it wasn't needed the factory wouldn't put it in there. Don't panic, just pull it back apart and make sure everything is where it belongs.

Thank you both for your responses! Exactly what I was trying to understand.
