What's the large washer behind the D44's pinion seal called? I called it a thrust washer, but I'm guessing that's not really it's name.
The parts counter people are useless and didn't even know that a pinion existed outside of a rack&pinion kit. Mine is bent into more of a spring than a washer, and has a hole in it. Given the old seal was rtv'd in, I'm guessing the PO drilled a hole in it getting the seal out.
For anyone who might happen upon this in the future, the dealer had them, two in a pack, correctly called the pinion oil slinger. Part #4031974. I'd wager they fit the D30 as well, given the pinion seal is the same part #, and you get two in a pack.
