[2003 Outback Wagon - possible AWD Duty C Solenoid failing]

Thank you Imdew. The independent shop sent the car to nearby Les Schwab Tire Center for a full alignment. The tires were off a bit.

[2003 Outback Wagon - possible AWD Duty C Solenoid failing]

Last month, I had an independent shop replace my 2003 Outback Wagon's front axle and CV joints to unsuccessfully fix a thunk, thunk sound that occurs when the car is warmed up and at slow speed the wheels turned a sharp right or left. Does anyone know if this might be the AWD Duty C Solenoid or ?
