Post high performance wheel bearings

Is there such a thing for our car?

if so:
were?
and how much?

thanx!

I would also like to know about this. I have had wheel bearings blow out and have had to have them repacked $$$$$. It would be an especially important topic if your car sees a lot of dirt. Any Ideas, I would expect some sort of answer from the rally people (SubieGal, etc.)

I will ask Lance at Vermont Sports Car when I talk to him on Monday. This is of interest to me also as I will be putting on spacers and 8.5" rims soon.

All,
The folks at Prototype Technology Group (PTG) that campaigns a BMW M3 take new bearings and pack them with synthetic grease instead of the standard stuff. The higher "stress" capabilities of the grease help them last longer. Simple as that!

Unfortunately it's not as simple as that. Subaru released a set of bad bearings to the public and then had to come up with a process for measuring the defective parts. Ask any of your Subaru technicians and they'll take you through the measuring process. I'm not saying the synthetic grease won't help, because it will, but just be aware that these bearings are defective and will fail on a regular basis.

My point exactly. It's not like bearings are rare, and it's not like companies that make wheel bearings are rare. But what is a good company to go with to make some custom reeel fast wheel bearings.

I have two bearings on the right side of my car in which I just destroyed. I've been forced to drive with them for some time. It's anyoning and I can't drive faster than 45(max speed is going down.)

I might be wrong, but the Subaru bearings probably aren't made by Subaru. I say "might be wrong" because FHI might own a bearing company.

Anyway, Timken, NHBB, etc. are good bearing companies and might have a bearing with the same physical dimensions. If anyone has the dimensions of the bearings, I'd be glad to cross reference. There are stacks of bearing catalogs at work. If there's a part number (not Subaru's, the bearing manufacturer's), that would be even better.

hey stever,
can you get F1 bearings

I won't know what the number is or if it is even recognizable, because it's been so long since I replaced the brocken ones (still on my car).

There are like 4-6 bearings on the subaru per axle (including the cvjoint axle bearings and diff-to-axle bearings) the ones I want are in between the hub and knuckle.

if that doesn't work, I'll have hell to pay (litterally).

I talked to Lance at VT Sports Car today and he said that they just use stock WRX hubs for their rally cars. They are rebuilt after every race and they use neo bearing grease. I don't know what that grease is.

We recently put some ceramic wheel bearings in a drag race bike at work. They were $100 each so $500 for front and rear wheels. They are suposed to give 1-2 mph in the 1/4.

BMW bearings are made my ***, a bearing company called ***. Seriously though, a high performance wheel bearing? Come on, use the stock ones how can a "performance bearing" help anything? If you drive hard they wear out faster, that's just the cost of racing. As long as they aren't defective as was said before, you should be fine for a long time.

There are differences in bearings. Typically, you'll find a few bearings in exactly the same size, but with different load capacities. It all depends on the alloys used, heat treatment, tolerances, etc. Rod ends are the same way. You can get cheap ones for less than $20 each, but the same size in a decent bearing will be over $50. The load capacity will be way higher and there won't be nearly as much slop.

Anybody know if Schumacher's Ferrari had Subaru wheel bearings

NEO bearing grease is a brand of synthetic grease available from Baker Enterprises, Signal Hill CA

the use of sythetic grease is for its higher temperature capability compared with conventional automotive bearing greases. grease has no impact on reducing contact stresses within a bearing.

nhbb does not make automotive wheel bearings. timken does make automotive wheel bearings. check out http://www.timkeninfo.com for a bearing part number cross reference and an application database.

the rolling elements within bearings are called just that... rolling elements. the bearing, be it ceramic or wood, is the rings, rolling elements, and separator. caveat - not all bearings have separators nor two raceways. ceramic rolling rolling elements do provide bearings with less running torque, but the contact stresses are higher. higher stresses = less life. there are techniques to bring the stresses back down, but your torque will go up. let me know (pm) if you need bicycle wheel bearings with ceramic elements. you got shafted on the price... even for 2002 prices.

my oem bmw wheel bearings were made by skf. i recently had my front wheel bearings replaced with timken bearings.

if you take two bearing catalogs and compare two bearings of equal chassis size and design, they may have different load ratings. this is due to differences in ball size and complement from manufacturer to manufacturer. it is true different alloys and hardnesses will have different load ratings, but each bearing manufacturer uses the same steel spec. and similar ht procedures yielding the same hardness for bearings. tolerances do not impact load ratings.
