From Pathfinder Wiki
This is probably the most effective step you can take to make a car faster. Start by polishing the axles. This can be done by mounting the axle in the chuck of a drill, holding a piece of sandpaper (320 or higher grit) on the part of the axle that comes into contact with the wheel, and then spinning the drill. Do this to each axle as your patience endures.
