axle locknut tool???

I have finally gotten all of my parts and now see how this bearing setup works on this. I see that thee bearing is locked on to the axle with a lock nut and washer. does anyone know the part number for this tool or know how to lock this bearing in place? if someone can help id appreciate it.

I assume you mean rear axle... I thought I heard those bearings were pressed on.

The front bearings are not pressed in but the races are.

Yeah the rear axle on a 91 2600i. And I thought so to but when I cut the old nut and washer off I thought it was a retainer then I seen there were threads. So idk what got do to tighten the new locknut and washer on.
