By Roll One
If a pinion nut is ever removed from the pinion shaft, it is recommended NOT to reuse it. Replace it with a BRAND NEW nut, even if the old nut is relatively new. Why? Because the threads on the nut, and the locking coating, are factory designed for a one time use. Even if a locking coating is used on the old nut, the "altered" threads can fail. Also a good idea to have spares. There are many posts and comments on the internet by individuals that have reused the old nuts claiming they've had no problems. They are simply taking a chance with lucky outcomes, even though it is NOT a guaranteed fail safe.
