I have a 98 Lego wagon,with an auto trans,that started making a grinding noise in the rear,it was faint and could only be heard in first gear.I found my brake pads were stuck and pretty bad.I cleaned the corrosion off of the rotors and put new pads on,lubricating all slide areas.While I had it in the air,I changed front and rear diff fluids with a synthetic blend,I also drained and refilled the trans fluid.The car has 186K and I've only had it for about 24K.I did the heads and gaskets when I got it.All seemed well except I could still hear the faint grinding.A couple weeks goes by and it doesn't want to back up.It broke free enough that I got it home and found this message board.Now,I'm learning a lot about Subarus and I have my trans out and the tailshaft housing off.The trans made noise when I ran it in the air,even in neutral.I want to fix it because I like this car and I usually don't get attached.I buy cheap and fix,drive it ,then sell-not this one.Thanks for any advice.
