Thought this might be a good diagnostic thread if any techs see same problem on the same type of car post it here. If i come axross the problem on more than 4 cars will post it .
This can be a good start Had 4 01- 03 outbacks five speeds all expanded center diffs. Fix was to install the awd center diff from 95-99 five speed. Is stronger awd unit. Heres one more had 4 97-99 imprezas with broken coged idler and bent valves fix 16 valves and coged idler /timing belt. Had 4 -8 99-03 outbacks with leading rear trailing arm front bushing hamered out fix press in new bushing. And so on the more imput the better
