patd Posted December 12, 2009 Report Share Posted December 12, 2009 Hey guys, I am reading on hear that wheel bearings are hard to find. I have a set of NSK inner and outter bearings P/N HR30304BJ and HR30208J will these work on my 71' 521? Thanks for any help :confused: Quote Link to comment
izzo Posted December 12, 2009 Report Share Posted December 12, 2009 rock auto has wheel bearings for your truck in stock too TIMKEN Part # 30304 RWD; FRONT OUTER TIMKEN Part # 30206M RWD; FRONT INNER Quote Link to comment
nukeday Posted December 12, 2009 Report Share Posted December 12, 2009 No. The inners are not correct. I just got schooled on this, too. Do a thread search on this topic. The inners are unobtanium, NLA, etc. A correct set was just on ebay for $200 starting bid. MKlotz70 sells a set of $20 adapters/spacers that will allow you to use 620 inner bearings. I'm not aware of any other solution if your bearings are truly fried... Quote Link to comment

At least the outters are right, Thanks again for the info.:) Quote Link to comment
nukeday Posted December 12, 2009 Report Share Posted December 12, 2009 (edited) In my 'no' answer above, I was referring to the listing at Rock Auto. I just looked up a couple of numbers, and I may have been mistaken about the PN's you listed. If the parts you have were ordered online, then it's very likely they are wrong. If these are NSK parts you've had around or ordered years ago, they might be right. I don't recognize the PN's. Maybe look for a cross reference on the NSK bearings to be sure?

dat521gatherer Posted December 12, 2009 Report Share Posted December 12, 2009 that part number may be correct. there was a heavy duty version of the 32kb02 that started with a hr. mklotz is the one to ask. Quote Link to comment

I am hoping it is the right one. I purchased my parts from IMC parts and the bearings were under the parts section for the 1971 datsun 521 truck, I checked again last night on there online site and the same part number is used on the 1973 truck, so I am going to keep my fingers crossed until I can contact mklotz. Thanks for the info:blink: Quote Link to comment

Thanks for the info:blink: These bearings have been really difficult to find, but that doesn't mean you don't have the right ones. PLEASE let us know what you learn from Mike. The real test will be when they are installed. '73 was the 620 series, last 521 in '72, so I'm suspicious... Quote Link to comment
