Shimano/Alfine 8, axle replace or build wheel?

I have three /Shimano/Alfine 8's and one is on my wheel that I broke the axle where the nut is. Hope I am explaining this okay. I can't put the wheel on because there isn't enough thread left since it broke off on one side, if that helps. Anyway, I am wondering if I should have a wheel built with one of the other hubs or take two hubs apart and replace the axel on the wheel that is already built? Can you pull the axle without getting all involved in this, or do I have to deal with like 13 parts to switch it out?

Cost is a big factor as this is one of my commuting bikes that gets beat up in winter and such. The bike isn't worth that much. I never built a wheel, but would consider it if it isn't that hard.

Suggestions? I am in Pittsburgh if someone knows a shop. I just got back from one that sort of made is sound like I am sunk on this one.

Depending on the model number on the hubs you have the internal assemblies are probably interchangeable.
If the model number is SG-S500 it might not be compatible with newer modelís. If the S500 logo is underlined it is a S500 B which is compatible with the SG-S501 hubs and can be interchanged.
I donít know if the more recent S7000 internals can be swapped into the older hub shells because I have not tried it.

Hillrider lives in Pittsburgh. Maybe PM him to see if he can help.

Good to know. I will look at that. Your advice could save me a hundred for sure.

Hoping to get guidance, but I know this isn't a normal question. Thanks all.

I'll give it a shot. Bike shops around here are insanely busy. Some just laugh at my situation. UGH. Must be nice to be that confident in future business after COVID is over.

Would you trust a LBS that wasn't busy during this time?
Successful bike shops are always busy this time of the year. It's Winter when they starve.

So? I usually fix my bikes myself, but this is more than I usually do. Do I build a wheel, or dig into the 8 speed? That is my question. It isn't about bike shops as much. They could care less if I can commute to work on my bike, they are living great with massive increase in sales and service. I would rather fix this myself, but I don't think anyone knows how to take these apart. I guess i could build a wheel, but that is quite a learning experience.

I am looking for advice or direction. Many shops don't want to touch this when they can make a buck much easier.

Just in case anyone searches, rebuilding a Alphine 8 is more difficult and involved in building a wheel, or at least that is my findings in my area. I am either going to build a wheel myself or have a friend build it.

Enjoy your ride!

QBP used to offer a couple of prebuilt alfine 8 wheels. They were pretty good deals. I have one on my bike, which cost less than the hub and rim would have had I done it myself. If they're still available, you could go that route.

Well this is a wilder ride than expected. My old hub that needed replaced was a 36 spoke hub and my other two were 32 spoke hubs. Ah, the job got tougher. The job is at a wheel builder here in Pittsburgh and he noticed this right away. UGH. He was going to get another rim and so on, but he decided to exchange the insides of one hub to another. I will fill in on details as I get them. Glad I know some bad ass people here in the Burgh that know bikes very well. Yahoo!

Now if I was to do this myself, I would look at this video.
