socorob Posted July 6, 2018 Share Posted July 6, 2018 I have the TTT Q45 setup on my car, and I used the rear wheel hubs with bearings that I got from the car I pulled the rear setup out of. The car had 130000ish miles on it. I want to put new bearings on when I change my spring rate soon. There are left and right versions of these. Some I found don't specify if they are right or left, several say right only, and I have yet to see one that says left. The part number from a lot of manufacturers seem to be 511011. Looks like it was used in the Q45 and Z32 Turbo. The non turbo Z32 has a similar looking hub, but from what I can tell has a smaller bore. I really would like to just get bearings and press them in, not get a whole hub. I see in pictures online these part numbers marked on the bearings: NTN HUB030 OL AB245WX 511011 MB BH511011 38030316 Does anyone have a part number for just replacement bearings for these, or for a left hand hub? It seems like the only difference that I can discern between the left and the right is the single little stud sticking out of the top. In the photos on some replacements, they show 2 holes in the top where it looks like you could press your stud out and put it on the side you need it to be on. Am I correct in thinking this? I want to have the parts in hand before I tear the car apart. Nothing worse than tearing something apart and not having the right parts to put it back together.

socorob Posted July 6, 2018 Author Share Posted July 6, 2018 See how the top one has 2 small holes and the bottom one has 1? Mine only have 1 hole with a stud in it. Just by looking, I can't tell any other differences. Quote Link to comment Share on other sites More sharing options...
pallnet Posted May 11, 2023 Share Posted May 11, 2023 (edited) Socorob I too am located on the Northshore. I just recovered my old account. I am also having problems finding the larger bore rear hub bearings. All of the aftermarket ones on Ebay Amazon and the parts houses locally in the Slidell, Abita and Covington area are wrong. They're all for the smaller hub. I'm at the point of ordering Skyline bearings from the middle east. They are OE factory Nissan parts at the best price I've been able to find at right under $300 shipped air freight. The smaller bearing ID is 43mm. The larger bearing ID is 45mm. (Correction from 50mm to 45mm. I got two 32 spline hubs mixed up) The larger hub is still in production in the aftermarket and sold stateside. There is at least one recently produced Nissan vehicle that uses the 32 spline count larger hub, but the bearing has the later mounting bolt pattern. They are cheap though. You can get a set of rear hubs with the wrong bolt pattern bearings for $100 off of Ebay, press the bearings off and you have a brand new set of the larger hubs. As far as the locating pin in the pictures. Some rear Ebrake setups don't use that style of bearing with the platform. If you need that style and all you can find is bearings with the locating pin on say only the right side. You can drill and locate the pin to the other side for one of your bearings. They're located opposite of each other for the side for the car it's being mounted on. A mirrored set. I hope I'm making sense.

calZ Posted May 11, 2023 Share Posted May 11, 2023 Do you have handy the cars or part numbers that still use those hubs? The only parts I could ever find were OEM for $300+ each, so I pulled two used sets from the junkyard so I'd have one pair for a backup. I'd love to have brand new bearings to match all the other new components Quote Link to comment Share on other sites More sharing options...

You'll have to figure out the various tabs. Many choices of vehicle or cross-reference. http://www.showmetheparts.com/timken/ Edit - Tried a few, it didn't find anything. If you live in an area with some industry you probably have a bearing shop nearby. They can find almost anything. I used to go to these guys. They'd take some measurements and go to the books. https://mcguirebearing.com/locations/#portland Edited May 11, 2023 by NewZed Quote Link to comment Share on other sites More sharing options...
pallnet Posted May 13, 2023 Share Posted May 13, 2023 "NTN HUB030 OL AB245WX 511011 MB BH511011 38030316" They will not work with TT/1st gen Q45/R32,R33,R34 rear hubs. The info for these hubs is not correct. I know because I'm now returning the second set I just bought from a different company than the previous set.

calZ Posted May 13, 2023 Share Posted May 13, 2023 Right, I was wondering about this part of your post: On 5/10/2023 at 8:26 PM, pallnet said: There is at least one recently produced Nissan vehicle that uses the 32 spline count larger hub, but the bearing has the later mounting bolt pattern. They are cheap though. You can get a set of rear hubs with the wrong bolt pattern bearings for $100 off of Ebay, press the bearings off and you have a brand new set of the larger hubs. Upon rereading, I'm realizing that you were saying you could get only the spline and wheel stud portion new. I thought you meant you could press the bearing out of the bearing mount and use it in the old housing. Quote Link to comment Share on other sites More sharing options...

I thought you meant you could press the bearing out of the bearing mount and use it in the old housing. It's a hub/bearing assembly for an FX45 (32 Spline and confirmed), not the FX35 (29 Spline from what I'm reading in my research),but there is an issue with this modern hub and bearing. I have a set that I broke down with plans of pressing the hub into a set of Z32TT/R32 rear bearings. The hub from the FX45 is beefier than the Skyline or Z32TT hubs by 5mm. The FX hub bearing ID measures 50mm and the Z32TT/R32 bearing ID measures 45mm (I corrected the mistake in my previous post). I had a brain fart from a distraction in the shop when I was pressing the FX45 bearing apart from the hub. I ended up separating both of them before I finished taking all of the measurements and comparing the overall dimensions to the Z32 hub/bearing assembly. My thoughts: I can machine the FX45 50mm hubs down and press them into the Z32TT/R32 hub bearings, it's very little work being that it's only spinning 2 hubs on the lathe, but that still leaves me using the more expensive and increasingly hard to find correct Z32TT bearings. Should I have a bearing failure in the future, the cost of one bearing will be more costly and troublesome to find. I'm thinking about ordering another set of aftermarket FX45 hub/bearing assemblies so I can finish my measurements. The mounting bolt location was the most obvious difference, everything else looked spot on at a glance when both types of hub/bearing assemblies were on the bench, but the measurements will confirm everything. I'm leaning heavily towards modding a spare set of spindles for the FX mounting bolt pattern, because the cost of replacement parts is cheaper, easy to find and I do like the idea of a beefier hub/bearing assembly.
