Question about 1990 Subaru Legacy

1 Answer

Constant whine when driving and wheels lock/skid in sharp turns

I have a subaru legacy 1990 model, and it makes a fairly loud noise, it is constant in all gears so I think it is possibly a bearing in the transmission and when you are turning sharply the wheel on the outside of the turn locks up and skids. any ideas on what it might be? I have replaced the rear dif so i am pretty sure it is in the transmission

    I actually work at a mechanic shop, so I have already tried that and the sound is definitely coming from the transmission. I have replaced the Differential. I was just hoping somebody would know something about the inside of these transmissions who might be able to guess what I am dealing with. I think it is something with the AWD but I am not sure

One way to track down the noise; since sound travels through metal its hard to pinpoint when driving in the car.
Jack all four wheels off the ground securely (preferably a lift) and run the car with the wheels spinning. Then, without dying, listen for the noise. The dealer can do it for you as well. But sounds like a bad differential.

    well, some cars have either a button inside the car that allows the driver to lock the differential so that all four wheels spin with one another, but some have an automatic locking or automatic unlocking differential. The advantage of it is that it allows the driver to get out of slippery situations, the disadvantage is that the inside wheel (in a turn) spin at the same speed as the outside wheel, so it will make cornering more difficult.
    Now, I dont know if the Subaru has this, but if it does, it explains the extra noise as well as the weird behaviour of the outside tire.

Wheels making binding noises when turning

I have this same problem with my 1996 Subaru Legacy 2.2 Wagon. There is a Subaru Service Bulletin #16-62-97 dated 5/16/97 with a Subject entitled "Transfer Clutch Binding And/Or Bucking On Turns". There is also an important follow-up to it numbered 16-64-99 dated 09/15/99 entitled "Revised Transfer Clutch Assembly Replacement Procedures" that should also be used should you decide to go ahead with the transfer clutch replacement.

I just got these Service Bulletins from my mechanic who got them from a Subaru dealer.
The estimate was about $700-$1000 to fix. This is more than likely the cause of the binding problem on slow, sharp turns.

Driveshaft is making noises

i presume that is a front wheel drive vehicle. you likely have a cv joint that is failing (constant velocitiy joint is the full name). if you raise the vehicle and turn the tire back and forth you should be able to tell which one is failing. rear wheel drives would likely need a universal joint replaced. replace both at the same time tho.

1993 subaru legacy front cv axles

First thing to have checked would be the front CV axles. If the rubber boots rip and allow the grease out it can damage the joints and they will make a clicking sound. Worn out axle joints can also bind and make it feel jerky. If they are making that loud of a noise it could become a safety issue, have them checked out soon.

Subaru legacy 4 wheel drive problems

What issues are you having? Is it jerking while making tight turns (typically u turns)? If so, your clutches for your all wheel drive are bad or your duty pressure solenoid located in the valve body is bad. This can happen if something hits the transmission pan and hits the solenoid.
