Picked up a 1996 legacy 5spd AWD wgn 142K mi, test drove it & drove it home with a real good howl coming from right front of car, ABS, on, car seemed to wander on when coming off the gas & slowing down for stops. car had some really bad maint, scary loose eng oil drain plug, trans was over filled. Previous owner replaced PS pump that I can’t so far match the missing filler dipstick cap.
Question is where to start? The howl, matches road speed, its not so much a low rumble, like I would think a bearing (been wrong before). Here is what I found in the trunk: completely worn out trashed mini spare & flat. I read Fairtaxtome previous post on 2001 outback “whats with the bad trans? “ which I will try, jack up front wheel & see if it rotates, listen for noise if it does turn.. then same for rear. . The other oil leak on garage was coming from rear diff; I assume it got trashed with high speed driving with the minispare. Looking for thoughts on this. 2nd question: if the rear diff(3.90 ratio) is leaking badly, just change it out? Wonder whether it’s the front diff as well, or maybe a wheel bearing? thx for reading
