There is about a 1/4 inch gap left. I tried to tap it in but no success. I reused the spacer from the old axle and I'm certain there is enough give in the axle to get the last 1/4 inch in. The hub is very rusty and have spraying it with spray lubricant and been cleaning it out with rags. Also, the axle looks to have been machined poorly with fuzzy metal shavings sticking out on the axle spindle.

I'm thinking I should sandpaper the axle spindle and wire brushing the wheel hub. Should I do one of the above or both? Potential damage down the road?
