Potential AT/Differential problems '91


Recommended Posts

I’m getting a loud whine from the front of the ’91 Auto Legacy.

 

It is present always and changes pitch on acceleration and deceleration.

 

It is present if I shift into neutral at speed and coast. Revving the engine in neutral does not change the sound.

 

It does not change if I make turns.

 

It seems very load dependent. When the load changes, like at the top of a hill, it will “squawk” if that’s the right term.

 

I changed the front differential oil with no change in sound. There was a little pile of fuzz on the magnet.

 

ATF fluid looks OK.

 

No torn boots.

 

Going under it tomorrow to see if there is anything else obvious.

 

 

What do you guys (and gals) think? How much trouble am I in?
