I just got my 1999 X about a month ago. It dosn't have 50,000 miles yet but it will soon. I'm wondering what all I should look at getting done for the tuneup. I already know it's gonna need a serpatine belt because it squeels every once in a while when the motor is cold. I just checked the brakes, they are still pretty good. Any suggestions? plugs, wires, filters? should I have the tranny and diff's filter and oil changed? I do small trailer towing if that helps. thanks for the input.

If everything else seems ok, I'd wait until 60k. Then do all fluids, plugs, plug wires, etc.

I would make the tranny filter change first!
