Angry D30 Outer oil slinger???

Replaced the outer pinion bearing and seal on my D30; cleaning up and found the outer oil slinger sitting in the bottom of the drain pan. WTF.. Fwaking D30...outer pinion race was a bitch to remove. Setting pre-load with a new crush sleeve wasn't fun either..
Should I worry about not having an outer oil slinger?

Plan on your oil blowing past the seal.


You don't need to remove any races or anything... the slinger goes on directly before the pinion seal does.

Outer pinion race > outer pinion bearing > slinger > seal > yoke > nut



IF you didn't set your preload at the upper end of the spec, you COULD possibly get away with adding the slinger where it belongs, only needing to replace the pinion seal and the pinion nut. Just make sure you have a bit more pinion preload than you did the first time you set it.

Or replace the crush sleeve since it's really not that much more work. Start crushing the crush sleeve with a press(just BARELY!) and it will be MUCH easier to torque down.

Thanks for the reply….Unfortunately my pre-load is on the high side (25in/lbs). I am just going to bite the bullet and do the job all over again. I have been running this a few days now; so far no oil puking past the seal. I am more concerned about sudden pinion bearing failure, then a little gear oil leak.
