Hi all--Newbie here looking for some help. Read the forums all the time, but have never posted before. My 98 Subaru Impreza is an automatic with 42,592 miles on it. It has begun to rattle, tick, whatever you want to call it during exceleration up hill, right at the 38mph mark. The minute you pass 38mph it goes away. Can not reproduce the noise on flat surface or downhill. Any suggestions before I call the service department at the Subaru dealer? Needless to say they are never very helpful when it comes to something like this. Any suggestions appreciated!
