Just read through this whole thread, some very good info in here I have a whine coming from the tail section of my tranny. The tranny is a 5 spd from a 96 impreza outback.

I just ordered my bearings from the local dealer yesterday. List price comes to about $211 and the dealer needed my VIN number to look up the correct bearings for my 06 WRX. Hoping to get the job done saturday and praying that I don't need to deal with the adjusting washers. I will measure the new bearings and compare to the old for a start. There is a detailed measurement process and some equations in the service manual. Two of the part numbers are also updated from what opposedforces.com lists which indicates that something is not interchangeable, either by vin number or due to the parts being updated and other stuff needing to change because of it..

Heuberger offers 25% off using online purchase, awesome price even with shipping from CO to PA.

My 5mt is in need of this repair too, been through this thread in full a number of times. Probably won't dig in till after winter tough. Mines not too noisy, no shifting or binding issues, gear oil isn't too bad with wear material on the drain plug yet.

What's the worst that could happen if neglected?

I'm only going to speculate, but I would guess that the further you drive => greater amount of wear => higher rate of failure=> increased cost.

Consider the exponential function, distance driven by expense. The greater the mileage driven, the higher the replacement cost becomes.

After reading this I am starting to worry if mine is making the noise but I don't know how to tell exactly what "whining" everyone is talking about : o.

I put mine up on stands, fired it up, threw it in 3rd and let the clutch out. The noise is louder than my motor. But once I throw it in neutral and let it coast down to 0 is gradually goes away. It has no relation to my engine rpm. Only road speed.

Do you think if I did this and recorded you'd be able to tell if mine is doing it or not? Ill try to get as high quality as I can.

We could try... I'm pretty positive I could tell if you're getting the same noise I am. I plan on tearing mine down before work this morning. I just read through all the other threads listed on PG.1 and they have a couple videos posted. You can try and see if they are similar to yours. Mine just started very faintly when I exited the fwy going to work. But after my 50mi drive home it was furociously annoying.

Yeah, I wish I could crank the radio to drown it out lol! But I am a diesel mechanic and spend alot of time listening for the slightest noise over a very noisy engine. So even the smallest "odd" sound on my car seems amplified. The blessing is a curse I guess ... Also I didn't get to it this morning... the wife drug me around town all morning. All fine with me. The longer my car is down the longer I get to ride in the luxury of her TSX lol!

So I put it up on jacks and drained the fluid well the magnet had some grime on it, and there were metal particles in it. Fluid looked okay, but when my uncle rubbed the grime / tiny metal particles between two fingers it cut him a little. These metal particles aren't normal are they? I saw a pic earlier in this thread of the particles someone got out of his. Mine aren't nearly as big. Once I get to a computer i can upload a picture.

So here is my plug after I pulled it out. Notice there are no big chunks at all. What came to mind for what this might be is my reverse gear. Reverse in my car is kinda messed up and when backing up hills if I get close to letting the clutch out all the way going uphill the gear will pop out to neutral (Ive done some research and found there is a pin coming loose for the reverse gear in my tranny that makes this happen). I am thinking this could be the cause of those metal shavings. I changed tranny fluid and put in good ol scotty's cocktail. Drove around for a little and WOW smooth as butter, and no weird noises at all. Any thoughts? Should I be worried about those metal shavings or is this normal?? Was going to change tranny fluid again in a few months to see if there are more metal shavings. Also on a side note. This is the first time changing tranny fluid since i've owned it in February so I am not certain the last time it's been changed.
Thanks all! And sorry for taking over the thread..

My plug looked very similar... A couple slightly bigger chips. But I pulled my center diff this morning and found this


No idea what to do about the clip. The bearings i'm going to get at the dealer.

Default Diagnosis anyone?

Hi there,
I'm new around here and I was wondering if I could get some help with diagnosing a certain noise my v4 sti is making. It is defiantly coming from the drivetrain (up front -nothing to do with the rear of the car) and I am reasonably certain that it is some form of differential bearing. The noise (whine) is only present during acceleration or when on the gas to keep a constant speed -no whine when decelerating. It is also louder the higher the gear, meaning that 1st is very quiet -possibly no whine at all- and 5th is the loudest.

Here is a video of 5th gear so you can hear what I'm talking about (I am going on and off the throttle just so you can tell the difference between decelerating and accelerating)


Any help is appreciated

V4 WRX STi Differential Whine? - YouTube

Any help is appreciated
I put the car on a lift, had someone bring it up to speed (like 30mph) and used a mechanics stethoscope to pin point the area. In my case it was obvious where the noise was with this method.

Thanks for the reply. I had planned on putting her on the hoist when I got home (neighbour has a hoist). Do you have any thoughts on what it might be? Eg. Bearings

Hello everyone,
I've been reading up on the forum for a few months and found a great load of useful information including this thread.
After taking the tail section cover off and pulling the center differential out on my 2004 Subaru Forester XT I found nothing extreme. Just the bearings that are a little worn out and a little noisy. My main concern is the burnt discoloration on my center differential. Before I took it all apart there was no clunking or banging in tight turns.
Is there any way to test the differential, FSM says nothing about the procedure.


Thanks

Default Thanks.

I wanted to thank everyone who contributed to this thread.
After replacing the bearings the noise is gone! My FXT drives like new!

Yikes, you can buy your own harbor freight shop press for less than that

That happens. Luckily those are relatively cheap gears. Be sure to replace all 4 xfer bearings when you fix it. You'll be shocked @ how many shavings are in the bearing underneath the Allen bolts.

Yes, and actually you can get them cheaper than that new. However, it depends on where you live. I actually did this in an industrial zoned storage garage in Charlotte, NC (meaning I could work on my vehicle). The place I lived, on the other hand, frowned on opening a hood in the parking area. Per the lease agreement, working on one's vehicle was not allowed. I've moved a lot in the last 5 years and I've lived in areas that have private parking or garages that don't allow renters to work on vehicles. It was also not in my best interest to run around and purchase a press that I'd later sell/give away/or take to the loft. It depends on one's situation and what accessibility you have. If I had a chunk of country property, I would definitely own a lift, pneumatic tools, and a lot of other toys with a large garage!
