ethree0 4 Report post Posted July 26, 2020 (edited) Rebuilding the H190 axle and hoping to put in all new seals. Searched and found some part numbers, but i worry that inventory and availability has decreased I have found the Pinion seal PN "NATIONAL 1979" which shows the factory part number 38189-P0101 as a good cross reference. (new information: Still available from the dealer per KELMO) Have found the Inner "oil" seal on Rockauto as PN "CENTRIC 41742009". Can anyone confirm fitment? Factory part number is 38212-73000 As for the outer "grease" seal, having a hassle trying to cross reference the numbers on the rockauto website. Factory part number is 43232-B5000 (new information: “Timken 1974” Should be the aftermarket cross reference. Will confirm once I order. ) Sources are getting a little harder maybe? I wish that the Nissan part numbers had some generic seal numbers that i could use at a seal vendor. Any help would be much appreciated!

KELMO 2,370 Report post Posted July 26, 2020 FWIW, the 38189-P0101 is still available through Nissan. The other 2 #'s are NLA. 1 Quote Share this post Link to post

KELMO 2,370 Report post Posted July 26, 2020 Is that H190 out of the 620 or something else? 1 Quote Share this post Link to post

Also doing the beebani watts rear end, so decided to disassemble in order to get it coated and then rebuilt. I was actually starting to wonder if the “oil” and “grease” seals are the same when compared to the early 4cyl D21 H190 axles. maybe there’s a better chance at finding parts for that one? 1 Quote Share this post Link to post
KELMO 2,370 Report post Posted July 26, 2020 Rear axle seal D21 : 43252-VW000. Not sure that is going to be the same size. 620 pinion seal #'s I came up with were 38189-A6100 and 38189-02700. 43232-B5000 will also fit the 720 38189-P0101 will also fit the 720 I would try that route instead of D21, just be cautious if you see something that refers to HD (Dually rear end) 1 Quote Share this post Link to post

Maybe this is why we are finding different numbers? Quote Share this post Link to post

I can confirm that the rock auto rear inner seal listed (41742009) is correct. we just did these on our truck. Quote Share this post Link to post
