Hi, new to this site, was wonderin if anyone could help me out. We have a 1993 Impreza, with 163,085 Miles. other than the usual oil leaks and such, it runs pretty good yet. only major problem right now, is that in the winter time, when the roads are bad, it doesnt want to kick in the rear wheels the way it should. last winter, it seemed that I had to almost work the throttle to try and get it to engage. and when it would, it did so with one heck of a clunk, almost as if the only way it would kick in, is when the fronts were slipping alot. I have owned four wagons before, (man do I miss them) they were all manual select 4WD, never any problems with them, so never had to figure them out, but this one, it has me baffled since I am not at all familiar with the AWD workings. I appreciate any info, and thank you in advance. Hope I can be of some help with some questions to come.
