Dear M. Jade,

If your axle nuts aren't tight enough, the hub will slip on the axle
splines and damage both of them.  It sounds as though this has
already happened and the hubs and axles may need to be
replaced.  It's necessary to be sure that you have axle nuts with ten
slots (rather than the older ones with six).  You must tighten them
to 360 lb-ft / 500 Newton-meters and then additionally tighten until
the next slot lines up with the hole for the cotter pin.  The main
risk is that the drive axles will no longer be able to power the
wheels reliably, or that the nut itself might possibly fail in which
case the wheel would depart from the vehicle.

This is not something you can be casual about.  If you cannot tighten
them properly yourself you must get someone to do it for you.

Yours,
David
