Washer behind d44 pinion seal

Hi all,

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.

I believe it is called a slinger. Its function is to deflect the gear lube away from the seal.

Cool, thanks. That was what I called it first, but they were equally confused. Guess I'll head somewhere better tomorrow :-)

Yeah, oil slinger or some call it splash guard. The guy who did my gears first left it out and my pinion seal leaked. Did it mself from then on.

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.
