I have a 1998 Subaru wagon with 41,000 miles and had no problems until now. I took it to the dealership for a routine oil change and to check on occasional rumbling/grinding noises that seem to occur when I come to a stop and accelerate again, the car actually seems to lurch on accelerating. The mechanic told me that the 'rear differential' needs to be replaced since the gears are worn out in it ($875, labor included). They also discovered that the 'oil separator plate' was leaking oil since it's become porus ($900 labor included). I am a bit shocked, because I thought I had a great, well maintained car. It's as if I went to the doctor for what I thought was little cold and the doctor told me that I need a liver transplant! I must admit that I know very little about cars, could anyone please tell me if I really need these fixes? I would think that the differetial problem is very important to fix first. I plan on taking a long trip this summer and wonder if I can afford to put off the repairs. Any opinions regarding my problems would be greatly appreciated! >Thanks a ton in advance!
