Exactly which bearings are needed to rebuild an R200 Diff?

I see in the Black Dragon catalog for the R200 they list the side carrier bearings (2), the front pinion bearing, and the rear pinion bearing. However, they don't list a pilot bearing like they do for the R180. Doesn't the R200 have a pilot bearing?

I'd really appreciate it If someone who has done a rebuild on the R200 could verify and list for me exactly which bearings are needed.

Also, if I knew exaclty which to order it looks like I could save quite a bit of money through Rock Auto for example instead of buying a rebuild kit.

Thank you Blue. Like the R180, it does look like there are 3 bearings associated with the pinion in the R200 but for whatever reason Black Dragon doesn't show the front ball joint bearing. And that is probably the one thats making the howling (whinning) noise.

Incorrect pinion and crown wheel contact is the main cause of diff whine. If bearings are gone than the pinion and crown will need work as well. Might be better off looking for a new diff.

You can use "bearing blue" or the red stuff, can't think of its name right now, to check the contact patern and refer to fsm. Its a lot of hassle getting it right if you don't have the right special tools to measure pinion height etc. A diff specialist would have a better chance getting it adjusted.

I wasn't going to try to rebuild it myself. I found a Trany/diff specialist who say he can do it. However, I was going to order all the parts myself (eg bearings, seals, gaskets) hoping to get good quality at a reasonable price and then just pay him for all the labor.

I dont know what quality bearings BD use, but all the bearing are still available through Nissan except the pilot bearing. They would have to measure it when they remove it or if its in good condition reuse it.

The four available bearings will cost about $230 IIRC.

If you are thinking of a rebuild, this would be probably the minimum:

Side bearings: 38440-N3100 (2)

Pilot bearing: 38335-N3100 NLA

Pinion bearing: 38120-13201 (front)

Pinion bearing : 38120-61000 (back)

Front seal: 38189-N3100

Pinion shaft nut: 38216-N3100

Side seals: 38342-N3100 (2)

Diff cover gasket: 38352-N3100

Breather: 38352-78600
