Lol, they're perfectly acceptable ball bearings im sure. Being that they are highly polished steel spheres, I don't think it would be a stretch (its fuking obvious) that those are reflections.
I wasn't until I saw SADfab BALL SACK. Where's my safety pin ..
So its probably reflection / ect but I'm seeing what looks to be a bunch of little weld spots on each ball ..
As for buying these off ebay .. they're cheap enough to try but what's the chances that' they're as good as / better than OEM ? Maybe there's obvious answers in the listing, but I'm a noob without $150 of tools to QC.
Yea, that's just a reflection. These things tend to happen when you have so many shiny ***** crammed together...
New ***** came today. Bought from the seller that Shuiend linked. The exact ones I bought are these, unfortunately either stock are not 13/32 or the ones I was sent were not.
I knew it right when I popped the first new bearing into the plastic retainer. It fell out whereas the old bearing remained in place. Will head to Harbor Freight tomorrow to get some calipers so I can determine the size I was sent. Hopefully can return.
Here's a pic to show the difference. 10 OEM ***** on top. 10 eBay 13/32 ***** on the bottom.
Night wasn't a complete bust though, the repacked hub with CV2 was pretty smooth. Can't wait to test it out in the car tomorrow.

I will say I bought the ***** completely based on some measurements I saw on here. It is very possible that I bought the wrong size originally. I have yet to repack bearings so I have yet to actually measure them myself.

It happens, I did the same thing without due diligence and double checking ..
Thanks for measuring that off Sean. I guess your Timken is 13/32. Now that I think about it, there's no guarantee that even different year OEM have same bearing size. Definitely measure your own before buying if going this route. Unfortunately this will add to downtime in many cases as most won't have spare hubs.
So far so good on my Mazdaspeed HDs. 1 track day at MSR-C (1.7CCW) and 2 at Hallett (1 CW and 1 CCW).
Lost a Mazdaspeed HD. It lasted a total of 11 track days (about 20 hours). So, no advantage there that I can discern. I slapped on a repacked China hub with OK machining.

Given how long these hubs last I've given up on the idea of repacking. I just going to for the best quality I can within reason and running them until they go (I always keep two spares with me).

If I don't see a significant durability increase out of the one I just slapped on (I don't have high hopes), I will do exactly the same. I'm really fast at swapping hubs these days.

Yup, I can swap a hub in much less time than the time it would take me to repack...also less messy too.
I made a tool to re-pack my front hubs , it rakes about 3 minutes to pump some fresh grease between track days, is anyone interested in one? My cost is $75 a picece when having 10 made.
i will make a batch if there are takers.
You isert the tool from the wheel side and it provides a seal between the front of the hub and the back bearing inner bore forcing the grease through the ***** and races, all the old grease comes out the upright side, i was not about to disassemble the bearings every time i re pack them. Let me see if this link works
