Tail shaft replacement in transmission=something to do with the AWD, Can any one explain. 1993 legacy sedan nonturbo auto. When pulling out slowly and wheels make tight ,sharp turning there is vibrating in the front and now in the rear rt. Vibes almost skip, no squeaking. Just had 4 new tires applied ,brakes checked = rear ones good for another 3-5000mi. Would like to get alignment and am soon. Not really bad there. How often do you really need to get or do you need to get all 4 or will the front do on these models? Was Told the vibe thing wouldn't interfere with wheel alignment. What else would have to do with the AWD that would caouse this vibe sensation? Please respond ASAP low budget but want to be safe for a trip in Aug. 09. Yhanks any feedback welcome. I need to see in my manuel what he is talking about. His words aren't in the manuel. Maybe someone can give me the correct meaning of the words from out of his mouth I can understand.
