Rear diff problem, I think
Over the last couple of weeks the car has begun making odd noises on full-lock low speed turns (think parking manuvers). Specifically a juddering/clunking noise that FEELS like the tires are scrubbing on the pavement.
(imagine trying to push your car sideways at low speed with the tires skipping)
I have a "FWD" fuse holder in my car (98 Legacy GT, 4EAT). When I put the fuse in, it makes the car "front wheel drive".
When the car is in FWD mode, the juddering goes away, and the car is sweet again. Which leads me to believe there is a specific problem with something toward the rear.
I have no problems at speeds above 20mph on sweeping turns, or in straightlines. Accelerating out of a turn causes some judder.
When in FWD mode - what is it doing to the transmission at this point - does it lock/unlock a differential?
I drained and refilled the rear diff fluid yesterday (using 80w90 as per owners manual), and the problem diminished some. The magnet was pretty thick with shavings... the diff fluid was black.
At this stage I'm finding some quotes for rear diff replacement units... factory is 4.44.
