Changing Rear Pinion Seal -- Part #s Needed!

[fumetsu]

I'm looking at this diagram here.

Trying to decipher what parts to order. My rear differential is leaking and I'm almost certain it is the pinion seal. Do I need both 41201C and 41252? Not sure if 41252 is a necessary replacement. Also, can someone point me out on the specific part I need for 41201C? There seems to be three variations for this very part.

All help is greatly appreciated. Thanks!

Are you sure that is the right seal? Toyota part site says that is for the 80 series and the LX450. Please correct me if I am mistaken.

Do you know how to replace this? It is not just a remove and re-install. You need to make sure you don't loose preload on the pinion bearings when going to back together. If you don't, search on pinion seal replacement. If you don't get much in the 100 section, search the 80 section. Same deal.

I thought I was in the 80 section.

My bad.

Your pinion seal splits in 2002.

2/2002 and earlier: 90311-38066

2/2002 till EOP: 90311-41009

I'd still get a new nut as well: 90179-22016

^ This. Trust me. If you are not sure, have someone who knows what they are doing take care of it. It will make your life better in the long run.
