Default Differences between 02 WRX and 01 RS brakes?

Due to problems beyond my control and design problems with Subaru's hubs and axles, I am in need of replacing my rear end. The diff is fine, but I need to replace the axles and hubs. I have been told to replace my OE equipment with equipment from a WRX to eliminate the RS bearing failures that I am having (been done by a local Texan to end his 13+ bearing replacements). I am now on my third bearing and this one lasted a short 58 days before failure... so i am done with this now.

My question is this... can I swap WRX axles and hubs without swapping the WRX brakes over? I have a beed on a local set up, but I don't know if it comes with the stock brakes.... so I am in need of knowing if I can reused my stock brakes.

Need clarification? Just ask....

Thanks for the help!

and if you are going though that many bearing something else is wrong one thing that would cause this that i could see would be if someone over tightened the laterial link bolts and this is happening

have you had a alianment lately?

edit
clarify previous statement
the rear brakes are the same on both cars

Do you see a lot of track time? How are you chewing up bearing that fast? FYI the typical upgrade where I'm from is to the beefier BC legacy bearings.

Oh one more thing: WRX sedan axles are wider than the GC stuff... make sure you get wagon axles. If you just swap hubs (and really no reason not to) you won't have to worry about that obviously.

doooooood maybe we should try using better grammar, punctuation, and spelling.

The rear brakes are identical and the fronts are larger but use the same caliper.

Was that so hard?

he's right
my 2001 RS and 2003 WRX = same rear brakes

fronts IIRC same caliper, different caliper bracket/diff rotor


the wheel bearing thing seems to be random.
i have 107k miles on my RS, OE wheel bearings

but note also, OE wheels as well.
I DO believe wheel size/offset has a lot to do with stress on the bearings.

hope this helps.

Burned through the first bearing in ~25K miles on stock wheels and tires....

Some cars are effected... some are not. The problem with the bearings is this... once you destroy and subsequently overheat the hub, the hub distorts ever so slightly from the EXTREME heat generated. Once the hub distorts, it is a ticking time bomb to EVERY wheel bearing you put in it.

The first bearing didn't over heat too badly and lasted some 25K miles. The second had to be removed in bits by an air chisel but lasted ~100K miles. And the third lasted me exactly 58 days before total failure that is resulting in the bearing siezing up and making the back end of the car "wag" as if it were on ice... it is very unnerving to first experience this failure on the highway at 70mph.

Soooo.... I should be able to swap the hub over from the WRX without too many problems...
