Outer Limits 4x4 Board

Reassembling the front axle, the swivel balls have surface rust on them.

I was going to just use some fine sand paper and clean them up.

Is this bad, it shouldn't mark the surface to much using fine sand paper

Wet and Dry should be fine. Do it wet it gives a smoother finish. The seals that run on the swivel are not a real good finish to start with so you should get no real probs.

thanks tony
