I used to have a 2000 GT that would easily get 32 mpg on the highway going 65 mph. (Shouldn't have sold it either! ) Now I have a 1998 GT, and noticed my highway mpg was not very good, even in the summertime. However, I also noticed a "scuffing" noise from the wheels as I was driving slowly through town, and I thought my brake pads were rubbing the rotors. Got an occasional *creak* and -groan- going over some bumps too. Turns out I had a bad axle, and once it was replaced, I noticed a difference in mpg right away. Shooting for 32 mpg + again!
Thank you!! I have exactly the same thing going on. I'll try to replace that. The sound has been irritating for months. I too was once able to get nearly 32 on the highway. I hope it works.
