You're asking for advice about bearing grease on a rotary forum? I don't think anybody's car has ever run long enough to worry about the bearings.

Mobil1 synth...
Available almost anywhere - WalMart, O'Reilly's, etc.

If you're paranoid, Redline...

Ahem.... How many front wheel bearing problems have I had? Fighting them to years because of those brakes.
I've narrowed down my next try to the amsoil, redline, and motul... Just need to remember which one of the three was the better and that's what I'll try... Along with some new and improved ducting

Sorry to get this off-topic, but can I ask what kinda problems are you running into?

The Japan guys kill the front bearings in a year / season with the stock, aluminum hubs.
This is why there are all-steel hubs available, which extends their life to up to 3 years / seasons.

This is the hardcore racing FC's...

Pretty sure Mazda didn't design their spindles and bearings to be thrown into corners at 150mph. Grease isn't going to help very much. Ever heard of such a thing as an upgrade?

What are the fast race car guys running at the track? Besides I haven't seen you post anything for him stating what doesn't work and why.

Thank you.

Bearings are overheating and the grease is failing which is leading to the bearings breaking apart and seizing... not fun when setting up for a turn @ 90mph.....

I only started running into this problem when I upgraded the brakes to a two piece rotor. My theory is not enough cooling and the heat is being transferred through the AL hat to the bearings and fucking shit up in a hurry.

Carbotech race pads aren't helping either....

Where might one find these steel hubs you speak of

I will cut you.

It's actually happening on the street as well... then again... we all know how I drive soooooo yeah.... It will also happen during a 20 minutes session @ LRP.... but hauling the car from 150+ to 60 every 63 seconds with a few other braking zones in between isn't helping. I would venture that if I put the stock brakes back on the problem would go away, but times would be slower for obvious reasons. The ITS guys don't have this problem and they're putting down similar times as I am...

Thank you.

I will cut you DEEP!

Cheapo grease doesn't work, can't handle the heat. The fast guys at the track in ITS are running stock brakes with upgraded pads, all they're allowed to do. The other classes have destroyed the front ends of the cars to get ducting to the brakes. This is what one of my winter projects is. Move the oil coolers back to just infront of the of the wheel wells and duct them from the front bumper. Fabricate a Y in the ducting to feed the oil coolers and the brakes.
Before I had some Naca ducts in the belly pan... my thought was that being a bit of a high pressure zone... or so I thought, it would feed the brakes... I'm not so sure it is.... so the front of the front bumper we all know is.... we'll see what happens next year... car is officially off the street as of Midnight tonight

Yeah, it's a combination of the heat transfer from the aluminum, and the warpage from the heat cycling...

I just remembered it's from KSP Engineering.
If you got access to YJA, they sell them there.
About US$400 right now...

I would think you would have access to resources to get someone with CNC to do them in the states?

[project86]

Im in one of those weird moods.. where i want to sell my FC... and get an FD... that runs of course.. -_-

[project86]

so i finally decided to get the hub off. Here it is in all its glory. Im gonna have to replace the ball joints and pretty much everything else that connects there too. I can't believe how expensive just the steering rack boots are... ugh

anyway. am i gonna have to have someone with a hydraulic press, press in the ball joints or can i muscle them into the new hub.

The 5 bolt hubs i have seem to rotate pretty smoothly... I think i made that word up .... so should i for go replacing the bearings in there?

[chibikougan]

I think they have around 130k on em if I remember correctly..

[chibikougan]

I would run them. Get em out on the highway or traveling and check for hot lugs etc. Its not to hard to tear it all down.

[project86]

Ya I'm not super worried about the bearings in there I guess for now. I just have to take off the dust cap to get to all of it right?
