They have several listed as rear outer which I think is the grease seal. There only 1-3$ each. That’s what I did this summer. 1 Quote Link to comment

I bought the national 1974 and gave them to a 620 owner since they fit their truck.... I'm going to add some info for clarification.... Quote Link to comment
Crashtd420 Posted March 30, 2021 Report Share Posted March 30, 2021 I just went through figuring out the wheel seal that goes in the rear hub... Greaser did post a correct part number.... Skf 550225.... and it is listed under the 520/521 I also found another skf seal that would work.... Quote Link to comment
Crashtd420 Posted March 30, 2021 Report Share Posted March 30, 2021 These are the dimensions for the factory seal.... I opted for a better quality with a double lip seal vs single.... Can be found on ebay and a few other places.... https://www.ebay.com/itm/132110448041 I just installed them last night with no issue.... 1 Quote Link to comment
Crashtd420 Posted April 1, 2021 Report Share Posted April 1, 2021 I just ordered axle shim for my 1972 521... you can find them from nissan under an 84 720.... They have 5 sizes available... Plus. 43086-b9500 - T=.150 The sizes are listed in metric... So the conversation is: T=.150 =.0059 T=.070 =.0028 T=.100 =.0039 T=.200 =.0078 T=.500 =.0197 Also incase your wondering they come split from the factory... I though mine were all broke till I got the new ones... still need them but I was surprised to see the split.... 3 Quote Link to comment

There used to shim the axle out from the 3rd member for proper adjustment. https://www.carpartsmanual.com/datsun/pickup-1965-1972/axle-suspension/rear-axle-case Quote Link to comment

uberkevin Posted June 20, 2021 Report Share Posted June 20, 2021 Yep.. still not getting how they work or what they are doing. Whats being adjusted? Clearly I get they are shims. Never had to deal with them, at least not yet. If the shim wasn't there what would happen? Quote Link to comment

If you had no shims the axle hub would bind up on the bearings.... Quote Link to comment

Clearly I get they are shims. Never had to deal with them, at least not yet. If the shim wasn't there what would happen? The shims adjust and set the axial clearance on each axle. For the 620 (521 is likely the same but check) the end play, that's the in and out movement of the axle, is only 0.0008-0.0059" or 1 to 6 thou. Newsprint is 0.004" so you may not be able to feel it. Excessive play will allow the axle to hammer side to side and that's not good. Too tight and it's rough on the bearings. It was set at the factory so save the shims and put back on the correct side. 3 Quote Link to comment
uberkevin Posted June 20, 2021 Report Share Posted June 20, 2021 That makes sense. Kinda like checking the crank thrust bearing clearance. Quote Link to comment
mklotz70 Posted June 20, 2021 Report Share Posted June 20, 2021 It's the equivalent of checking the front wheel bearings....you know how you tighten them and then back the nut off to allow a bit of play. This end play....axial clearance......check is to make sure that your not causing the bearing to bind by forcing the axle to tightly against the thrust block inside the diff. Download the manual. It's page 123/124 (RA3 & 4). Hmmm....I just learned that I can copy/past from my adobe. lol....cool. :) It's hard to see in the second pic, but you use a dial indicator and (typically) a magnetic stand to check how far the axle will move in and out. Too little causes binding...too much makes it sloppy......not sure what the drawbacks are...noise? premature wear? LOL......I knew I posted something about it years ago......just found a YT vid I did..... 3 1 Quote Link to comment

I sold my last wiper assembly a couple weeks ago, I have a RHD one but it is different. Hey I realise this is a loong shot since this post was from years back. But do you still have a RHD assembly by any chance? 1 Quote Link to comment
