I am looking for some help with a 2002 Legacy Wagon L, 5sp manual with 55K. About 2 weeks ago, the car got a bad vibration when I turn left and only when I turn left. It doesn't happen ever day, seems worse in the cold or if I am on an incline. Only happens when I am moving slowly and not fast. It is not a subtle vibration; it feels like you are driving over a rumble strip. It never happens when I go right. My left front CV joint was bad and the entire axel replaced. I thought that had fixed it, but about a week later it started up again. My mechanic, who suspects the transfer case, replaced the CV joint again just to be sure that the CV joint he put in wasn't bad, even though he did not believe that was the problem. And of course, driving home from the shop, it did it pulling into my driveway. The thing that neither he nor I understand is if it is the transfer case (viscous coupling type) why only left. Could it be a steering rack problem? Is there something I can do to test like putting it into front wheel drive (is this safe for the car)? I am the original owner, purchased 9/25/01. I replaced the tires last year and they are matched. Any insight would be appreciated. Thanks.E.
