Question:

How to tighten spindle nut ?

The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it stops, then back it off so the cotter pin or washer tang fits into the next indentation of the castle nut.

If you click on the video link I provided, and forward to the 1:40 mark, you can see one of our techs demonstrating how to correctly tighten a spindle nut.
