Ratpeters

I have a 1997 Outback with 160k miles. Since I've owned it, I've replaced both front calipers because the pistons seem to have hung-up. I thought that would take care of my problem which is that the driver's side always seems to be wearing much faster then the other. Also, when I had the discs turned, they commented that I had some overheat damage on one of the discs. I lubed the slides but what more can I do? Even now after you drive it a while, you can feel more heat coming off the driver's side disc after you stop. Also, I seem to have a slight shimmy of the steering wheel at speed. Are these issues related? How do I correct the brake wear part?

Any idea what a dealer would charge?

I have a 97 with 160k on it. I bought with 90k and so far have done 2 set's of head gaskets. Supposedly, the 2nd time the dealer said that Subaru had just re-engineered the head gaskets so we'll see. If they go again I'm finding a short pier and..........

I've got a 2000 Legecy GT sedan. Recently I noticed a oil smell similar to 90wt gear oil. I took it in and the mechanic said that the auto tranny was low and that some must have put auto tranny fluid in the differental... so he changed the fluid in both and things seemed fine for a couple of months then the smell returned. Now the auto tranny fluid is a little low but the differental is now a little high. Is it possible that a leak at the front of the auto tranny could force the tranny fluid into the differental and basically over fill it?
