5-lug hub help needed!!! (pics provided)

[shomo172]

Recently, on my recently bought s13, my wheel bearing went out and I really needed to change it on my 5-lug S13. I read online that the OEM wheel bearing for an S13 would fit into the aftermarket hub. I took the hub off using a 30mm socket. I don't think the hubs were from an S14 cause the bolt of the S14 is supposed to be 32mm. Needless to say, the S13 wheel bearing I bought seems to be too big to press into the 5-lug hub.

Then after I took it apart, I realized that the brakes up front were 2-piston brakes and looked like Q45 brakes, leading me to believe that maybe my 5-lug hubs aren't aftermarket and that they might be Q45 hubs. So if that's the case, would I need to be buy Q45 wheel bearing? (naturally).

Anyways, I took pictures of everything while its apart to see if anyone on here could identify anything so that I can know which wheel bearing to buy.

Also, if I have Q45 front spindles, can I still bolt s13 coilovers to them? I would think that you still can but I'm not sure. Any information and identification will be helpful (lower control arms, spindles, hub, ect)

I did search but the information is much to vague and scattered and I really wanted some hands-on advice. Thanks. Here are the pictures.

Those are NOT aftermarket. They are also NOT Q45 or some crap. They look like S14. The differences between the S13 and S14 spindles are not the size of the nuts. They are a larger shaft for the bearing, different lower ball joint taper, and larger spindle to strut bolts. Remove one of the bolts that holds the strut to the spindle. If there are spacers inside or the hole is much bigger than the bolt then they are S14 front spindles. In which case you need a whold new hub as the bearings are not sold separately.

[shomo172]

I went out there and checked just now. The strut holes, spindle holes, and bolts all line up and are the same size. Does this completely rule out that they are s14 spindles?

Also, is the inside of an s13 hub supposed to be smooth, as opposed to this one having grooves in it?

Those brakes might be J30/Q45 but Q45 front hubs don't work only J30 hubs do.

These don't look like J30 hubs though because J30 hubs have 5mm longer studs.

Also you can fit S13 bearings into J30 hubs which is how you modify them to be used in an S13.

[shomo172]

Yeah it can't be J30 then because the s13 bearing I bought is clearly too big to fit into this hub. I'm really stuck. I need to figure out which bearing or hub to buy so I can drive my car again.

Did you measure the bearing? You could make all your measurements with a set of digital calipers and call a bearing retailer and give them the sizes and they can sell you whatever you want.

Also, did you measure that bearing that you bought? Maybe they sold you the wrong one?

[shomo172]

I don't think they sold me the wrong bearing, I just think my hub is a different hub.

At this point, I don't care about the bearing an would rather just replace the whole hub assembly, but I don't know which hub it is.

This image shows an S14 spindle on the left, and an S13 on the right. Your spindles are S14, as are your hubs. The strut bolts probably have spacers inside the spindles that you didn't see because you didn't take the strut completely off. Just looking inside the hole it looks like there are no spacers. I bet that S13 bearing doesn't fit on the spindle either does it?

Also, you did notice that the inner bearing race is still stuck to the spindle right? You're going to have to cut/chisel that off...

Take the bearing and hub and bring it to parts store and match up new bearing

I actually unbolted both bolts on the strut and pulled it off the spindle and looked inside and it's clearly flush and has no spacer.

Also, I just test fitted the bearing the the spindle and it turns out its too big. If anything it should be too small, so I inspected the part number on the box and the bearing and they were different so I'm guessing autozone sold me the wrong one.

And yes I did notice the bearing race. Turns out it wasn't stuck on the and I was able to lightly pry it off thankfully, so my spindle shaft is completely isolated.

From this point, should I even bother trying an S13 bearing with the proper part number? Or is it pointless cause they won't fit into these hubs?

What size is the hex on the bolts for the strut to spindle? If they're S13 bolts they should be 17mm hex, 12mm bolt diameter. If they're S14 bolts they should be larger. Maybe those struts are either re-drilled or are S14 as well. The shaft for the hub does not look like S13, judging by the pics.

The bolts were 17. You're right, it doesn't look like the s13 one in the picture, yet the strut bolts are the same.

Also the axel nut on an s14 is supposed to be 32mm and this one was 30mm which is the same as an s13.

All of this is making me really confused and wondering if its not s14 or s13 and something completely different.

As far as I know S13 or S14 are the only options. Nothing else crosses over. You can use J30 front hubs on the S13 spindle, but you have to swap the bearings and machine a groove in the hub itself for a snap-ring. In that case it would still take standard S13 bearings though. Maybe the bearing was packaged wrong, it happens from time to time. Bring the hub with you to the auto parts store and double-check there.

[shomo172]

The bearing the sold me is definitely the wrong one. But if it is s14 one then I need the hole assembly correct? Cause it can't be an S13 hub.

I would pull the seal out of the hub and take it to the parts store to double check. It may be aftermarket, but it doesn't look like anything I've seen. Maybe it's a J30 hub, in which case the proper S13 bearing will fit. If it was S14 then you cannot get the bearing, to the best of my knowledge.

[shomo172]

I looked up a picture of a J30 hub, and it looks exactly like mine. But I'm wondering, do I need an S13 wheel bearing? Or can I buy the whole hub assembly with the J30 bearing in it?

[ghoti]

No you need an s13 bearing to make it work on you're car

[shomo172]

Hm, okay thanks. I also found out that my brakes are in fact J30 brakes. I'm still a little confused about my spindle but I think it really is just an S13 spindle, thought I can't find any pictures of J30 spindles or Q45 spindles.

[shomo172]

I think I figured it out. I'm pretty sure I still have S13 spindles. The edges were grinded off like in this thread: Hybrid How To: s13 5lug front hubs for under 100$ : Nissan Tires, Wheels, Brakes and Suspension (http://forums.nicoclub.com/hybrid-how-to-s13-5lug-front-hubs-for-under-100-t346514.html)

My spindle looks identical and all the bolt sizes line and a tell me that it's an S13 spindle.

I'm gonna try and get the S13 bearing and go from there.
