View Full Version : Are Subaru wheel bearings

made of cheese?

Just wondered really as pretty much everyone I know who runs a new age STi and has been to the ring more than a couple of times has knackered at least one bearing............

Is this an AWD trait?

I dont think its an 4WD trait, my elise munches wheel bearings aswell. Had all 4 replaced before a trip in July, now 2 of them need done again after 5000 miles.

I think its a combination of heat issues and lateral loads. Subaru's and elises are renowned for there grip before they start to slide (and whilst sliding for the scoob) so the bearing takes WAAAAAYY more energy in an aquward direction. Also, the hotter they get, the quicker they fail, so the hotter your brakes, the more heat is passed through the hub and is soakes up by the bearing.

Thats a non technical opinion, by the way, i'm just guessing

Hence the reason why mine are fine! :lol:

Maybe this will change with my new bits and bobs.

This explanation sounds pretty feasible. :thumb:

I never changed the wheel bearing on my classic scooby, but i think one was on its way out after 12 months ownership. I did change the wheel bearings on the 1986 audi ur quattro all the time. The rear bearings would last about 6 months if i was lucky and the front would last a little longer.

Mine are OK. I know Simon has had one replaced.

Ooops, just seen that in general :shame:

I'll text him for an update.

It may be that Subaru discovered this issue and thatís why the MY05 cars have bigger hubs and different PCD on the wheels? The extra weight is not good for the original sized bearings.

My car eats bearings.
Had new ones fitted in Winter.
Replaced them 3 Months ago.
And today the right front one went again. :angry:

500 laps - 2 rear wheel bearings.

:huh:

3 fronts in 55k, 2 hubs & now 2 rear bearings. Maybe I am not trying hard enough :lol:

Stan

65k in the barge,and wheel bearings are fine. :P

2 rear wheel bearings at 40,000 miles prior to first ring trip and after second trip ok so far.
main dealer i bought my car from recommended wrc grease for wheel bearings if going on track as dissipates heat better

Glad to see that they have cured the problem, not :angry:

Was told the other day that although the hubs are larger the wheels bearings are still the same as the old ones, size, everything :huh:

A pair of rears cost me over £400 fitted so get saving you lot!

Not even that though, cos if they were made of cheese at least you could have em on crackers after!!!!!!

My MY02 (87000 km.) is sounding very weard at the front left wheel, it did it after my last lap in October and now is doing it again when hot... is that it?

I'll keep you informed...

Juanjo :(

A wheel bearing will usually show itself by a whirring or rumbling sound. This will be more pronounced when you go round a corner. The side which is on its way out will sound worse on one corner and better when going round a corner the other way.

Yes it is when I'm at the roundabouts, and left way sound worse... To the workshop next week!

Could be dangerous driving to work at very slow speed in the meanwhile?


another bill coming...

They usually make the noise for a fair time before they fail. I think Uncle Benz said even if they do fail it doesnt knock the brake pad out causing brake issues as it can on some cars.

Should be ok to drive on but get it booked in ASAP

Juan, be careful as it can take out the hub as well. That will be an other £100 Sir!!

Juanjo

I dont know what the hub is but I'm trying not to move it till getting to workshop... is it interesting to get "good" wheel bearings or there is no difference (or options)....


Thank you guys for your advice...

hub is part bearing sits it. There is only 1 type of bearing iirc but you could ask it to be packed high high temperature grease, that might help a little.

Juanjo
28-10-2006, 01:49 PM
I had a look on ebuy, not much choice really...

I supose it's this (from autolink uk): http://cgi.ebay.co.uk/Front-wheel-bearing-...4QQcmdZViewItem (http://cgi.ebay.co.uk/Front-wheel-bearing-kit-Subaru-Forester-Impreza-Legacy_W0QQitemZ160007697118QQihZ006QQcategoryZ104 24QQcmdZViewItem)

It is around 50 pounds sent to France, (so they charged you around 300 pounds to install them!! bloody working hour rate on UK garages!!!

I see front and rear are different.

I saw the hub, it's clear now, thanks again.

well I'm back from the workshop, I have not decided yet what to do...

The colleague at the workshop told me that noise is coming from the combination of bearing+hub and little pad left. So it's not urgent but has to be replaced. And he says if I change bearings I should change hubs too.

This guy is trying to fix on his MY04 the Housing+nearing+hub of MY05 (apparently Mitsu origin). To do this he will have also to make rear train adjustments (to keep same width on both trains) and to drill the new hub to fit the standard 04 rims.

We'll see the final bill of this modification and then I'll decide if to replace by 02 bearings or 05 whole set.

In the meanwhile I take the advice of better grease, and in any case I will make a big air intake from the foglights hole to the inside of the wheels in order to reduce working temperature... and I keep thinking to take weight off is always going to help.

Has anyone tried that modification? comments very welcome... are the 05 bearings the final solution?

And it seems they are definetely made of cheese these Subaru bearings... :angry:

Gorisan has already said earlier in the thread that the bearing have gone in his MY05 car, so it seems they are not the answer.

i believe that the 05 bearing is exactly the same as previous years but the hub is bigger in a vain attenpt to disipate the heat a bit better. From what I understand it has not really worked :(

Juanjo
01-11-2006, 10:50 AM
Ok guys, I see it may be an improvement but far from the final solution yet... may be not worth the investment...

Juanjo

Job done, two front bearings and hubs done, plus wheels geometry on both trains, total 1300 CHF (550 GBP)... :(

I had a look to them, left hub was in very bad condition (many long left turns at the ring...), right one had already marks...

I hope they last this time...

Juan, glad that you have it sorted and to be honest thats not a bad price for bearings, hubs & geometry as I paid around £450 for 2 bearings & 1 hub earlier this year.

I now have all 4 bearings changed so I hope that I can get a few miles out of them now :lol: There is a flaw with the bearing / hub design on the fronts but it appears that Subaru have no intention of improving them. Oh well, not to worry :(

Can&#39;t you get like - Group N or WRC upgraded bits for these ricers?

I&#39;m still considering buying one but not if bits fall orf and break all the time&#33;

Might be a 406 V6 Coupe after all :D

group N would be the same but they would change them after each rally. WRC - yea right, bespoke I would hazzard a guess.

The rears on my car did over 50k before they needed changing fyi, the front left was changed at 24k & 50k, the front right at 50k, with new hubs both at 50k.

I had 2 classic&#39;s before this car, one did 60k & 1 40k both over 2 years & neither needed a wheel bearing during that time, the newage is 200kg heavier so that cant help can it? :(

They are very reliable in the whole as most Jap cars are :thumb:

Don&#39;t rule the classic out. Garys was a lardy new age as well. My classic Turbo did 20+ trackdays in 18 months as well with no bearing problems.

Are the coupes reliable then being french?

A friend who had a Scooby and got in pretty tight with the Subaru test drivers told me that the Karussell actually loads the bearings in a way that no other turn in the world does. They apparently had a lot of failures a few years ago, and he seemed to think that the problem had been ironed out.

I have dropped my speed there now as I feel it was killing the car. 10mph slower & hopefully the car will last a bit longer :lol:

jamiem from off here never takes the VLN Golf through there on a TF for that very reason Ed, and they run Audi A3 bearings in it because of the amount of failures they were having.

Mine went the week before i went to the ring but that was due to the driveshaft nut coming undone&#33;&#33; most of the time when they go they trash the drive flange as well :(

all the bearings since MY99 are the same and the hubs and drive flanges are the same until MY05, and as you say probably made of Cheese :lol:
