Bearings
Hey Guys,
I have been reading a ton of Threads and posts about front bearings. My NA8 ONLY does +16 races (lemons racing). We haven't had a bearing failure yet, but from what I am reading it just a matter of time. We do repack our bearings between races (went a full 24 with Mobile 1 and no failures)
Here are some pictures of the Drivers side hub after 30 ish hours of racing (practice and race).
If you look really close there the grease is two colors. The really bright pink is the same color as fresh grease. The other color is leaking out of the bearing. It looks like it might be a little cooked but i'm still new to doing this.
I just bought some Schaeffer's 248 from advanced-autosports.com Mmmmm Schaeffers.... They are known for their motor oil and for having the highest content of Moly in their automotive lubricants by quite a bit and revered on "Bob is the Oil Guy". This is a really good quality for our little miata bearings.
End of informational section. My question is, has anyone had any experience with GSP Bearings? I found them on Amazon today, they are a decent price ($60) but what really caught my eye was the hub construction and just how different they looked when compared to the standard Timkin bearings.

It looks like beefier design?? I was thinking about getting a set opening them up and repacking with Schaeffer's and possibly replacing with the ceramic ball bearings. According to what I have read the high level of precision means that one ball wont receive higher loading then the other ***** and then blow up.
End game is to build a much beefier front bearing so I don't need to rebuild them between every race.

I repack the rear bearings, they come apart the same way as the front ones.
On the front hubs the two pictures you linked look like the same exact hub to me. These hubs are a crapshoot and there's 2-3 different styles of the casting/machining that exist and only 1 doesnt suck, and you can get any of the styles in any color box (timkin, detroit axle, gsp, etc, the only difference is the color of the box). $60 is super expensive though the detriot axle ones are like $20.

Thanks for the tip! I didn't know the rear bearings were rebuildable. I ordered some Dura International bearings on Amazon and some Timkin bearings for the rear.
I can also report that the Schaeffer's 248 is the stickiest, tackiest, goopiest **** I have ever touched. It coated my gloves like nothing I have ever seen. It was like packing honey. Think Alien primordial ooze. If this stuff comes out of the bearing it will be some kind of adverse act of quantum physics. T-minus 46 days till race day!

The Detroit Axle bearings have gone up in price :(
$42 on their website (I haven't found them elsewhere, link for cheaper?)
Get something new and follow the guide to repack with something good. I just used the Schaeffer's 248 and will report how that goes after our enduro in April. We went a full 24 on new and used bearings with Mobile 1 synthetic grease with no problems on the front. The rear did begin to loosen up at the end of the race but those had factory grease (that's going to change from here on out, THANKS LEAFY!)
Here is the link to the step by step guide.

I hope this helps!

The ABS ones are cheaper. You can just knock the ring off apparently. Found them here.
