Default Transmission noise fixed! center diff bearing

I didnt want to hijack the other thread, but hres the background info..
http://forums.nasioc.com/forums/show....php?t=1147847

Thanks Jose (pacobeagle) for diagnosing and fixing the problem.
To sum it up, I had some strange whining noises coming from the tranny, and subaru quoted me 3500 to fix. I called up Jose and he suggested to put it on the lift and use a stethoscope. We found that most of the noise was coming from the center diff. He suggested that I order these 4 bearings:


top left G32204 roller bearing
top right G33008 roller bering
bot right G23017 ball bearing
bot left G25501 ball bearing

here are the ok bearings

and here is the one that was making all the noise (i think top right)

every single roller was out and lose in my assembly, jose found all 14 and put the new one in.

the transmission sounds awsome, I can finally hear the straight cut gears without that annoying whiine/whir

BTW my center diff was in good condition
Subaru inspected it and said it needed to be repalced a few months ago

I'm pretty sure this is the noise my car is making. Should I just take it to a local tranny shop and have them listen to it? How much do you think the repairs will run if the problem is similar?

Well, the transmission doesnt have to be dropped to work on the center diff, so its fairly cheap(compared to breaking a gear). The actual bearing I needed was only 40 dollars ordered from subaru, but we replaced them all ($140) just to be safe. If your center diff is damaged (it hsouldnt be unless you autox), those run about 500 dollars. Shouldnt be more than 3-4 hours of labor in any case.

It seems as if I am dealing with the same problem, but before i go ahead and do anything i want to get a professional to diagnose it. My question is, in the case that its just the bearings, will there be any further/significant damage done to the central differential if i continue to drive the car ?

Hey! Good job with the search.

I would be mor concerned with damaging the transfer drive and driven shafts than the center diff. Any time you have bearing failure you risk damaging the surface they ride on more than anything else.

For instance, front wheel bearings. When they go bad they tear the heck out of the hub unless you catch it early.

So, use your own judgement but I would not wait too terribly long.

I know this is an old thread. But maybe it is the same problem I am having. Its an 02 vf34'd wrx with 108000 miles on it. I am getting a loud whinning sound only while under load/acceleration. It actually almost sounds like those wrc rally cars when they are accelerating. hehehe. When I take my foot off the gas, the whinning pretty much goes completely away. It used to do this quietly in first and second, but now it does it on all gears much louder it seems. Anybody?

I have what sounds like the EXACT same problem as boostedscooby2002. Gear-ish sounding whine that increases pitch (not volume) with speed, only increses volume under increased load, and only has any volume from about 35-65 and no volume if not under load and no volume under deceleration, even if still in gear.

To recap, only gear whine while under load from 35-65ish, regardless of gear.

Anyone?

Just thought I'd add some info to this post since I'm sure people are still using (like me) when they have a whining from under the car. i had a hard time looking up the parts cause the numbers listed but eventually the dealer traced all the number changes.

The updated part numbers for the bearings are:

G32204 roller bearing - Subaru Part# 806322080 subaru $56.68
G33008 roller bearing - Subaru Part# 806330120 subaru $49.24
G23017 ball bearing - Subaru Part# 806230170 $53.54
G25501 ball bearing - Subaru Part# 806255010 $62.06

Prices were from my local dealer so I'm sure they will vary some at other dealers.

So if I am going to be replacing my center diff with a new oem center diff from Subaru, and not knowing what bearings may or may not be bad, should I replace all these bearings as well just to be safe? I really dont wanna spend another $150 but without looking in the trans their is no way of knowing. And I would hate to have it at the shop and them tell me I need new bearings and we dont have them.


However, if I only used 1 of the bearings, could I return them to Subaru??

The noise on the car has gotten louder and now I'm hearing a humming noise that seems to be coming from the passenger front side. The noise only starts at 40 mph and stops at 50 mph. It only happens when you are accelerating, doesn't happen in neutral or when you are not on the gas. It happens in all gears though.

Any clue on what it could be? I'm planning to start dropping the tranny today and see what I find inside. Wondering if it's even worth it trying to fix it or to just get a replacement.

I did it on an 08. The humming you have sounds more like a wheel bearing. I had a humming noise in my car but couldn't figure out where it was coming from, so I had a passenger climb around while on the highway to determine its source.

The rear wheel bearings and the center diff bearings on my car went within 1500 miles of each other. The center diff bearings are not too bad to fix on your own, they are relatively cheap, and you can do it with the tranny still in the car.

I thought wheel bearing noise was a constant noise that gets louder as speed increases? This humming only happens from 40-50mph.
