On the 1990-1999 Subaru Legacy, automatic-transmission Legacys use an electronically controlled transfer clutch (governed by the Duty C solenoid) to send torque to the rear wheels. When the clutch pack sticks engaged or the Duty C solenoid gets dirty/sticky, the AWD stays locked on dry pavement and cannot relieve driveline wind-up, producing 'torque bind' - juddering and hopping during slow, tight turns. Mismatched tire diameters accelerate the wear.
Common Symptoms
Shudder/hop/binding in tight low-speed turns
Driveline lurch when parking or making U-turns
Symptom disappears with the FWD fuse installed
Worse when cornering, absent on straight dry road
How to Fix
Confirm the fault by inserting the under-hood FWD fuse - if the binding disappears, the transfer clutch is the cause. Fixes range from cleaning/replacing the Duty C solenoid and servicing the fluid to rebuilding the transfer/tail section. Always run four matched tires to prevent recurrence.

On the 1990-1999 Subaru Legacy, the Legacy's front hubs use tapered roller bearings that require correct axle-nut preload. On these cars they are a common wear item: an improperly torqued axle nut, high mileage, or water intrusion leads to a growing hum/roar that rises with road speed and changes when loading the bearing in a turn. Left unaddressed the bearing can develop play and damage the hub.
Common Symptoms
Humming/roaring that increases with speed
Noise changes pitch/volume when turning left vs right
Growling from one front corner
Play/wobble felt at the wheel when rocked
How to Fix
Replace the worn wheel bearing (press-in on this generation), set the axle-nut preload to spec, and inspect the opposite side. Confirm the noisy side with a sway/turn test - noise that grows when weight shifts to one side points to that bearing.

On the 1990-1994 Subaru Legacy EJ22 2.2L SOHC, early Legacys used federally mandated motorized passive shoulder belts that ride a track along the door frame, driven by a small motor and triggered by door-jamb switches. With age these jam mid-travel, slip off the track, or stop moving entirely as the drive cable frays, the track binds, or a jamb switch fails. It is one of the most frequently reported complaints across the first-generation cars in NHTSA data.
Common Symptoms
Shoulder belt stuck partway along the track
Belt will not move when door opens/closes
Grinding or buzzing from the belt motor
Belt slips out of the track
Motor runs but belt does not move
How to Fix
Clean and lightly lubricate the track and verify the door-jamb switches and fuse. A frayed cable or failed motor requires replacing the motor/cable assembly or the complete track unit. Owners commonly disconnect the motor and leave the belt latched, using the lap belt, as an interim measure.
