My new axles/retainer plates did not come with new nuts.. To answer my own question above re: using lock washers, did some reading and found that the Mopar nuts are torque nuts (they crush/deform to hold their tension) - which would be important given the vibrations and potential to loosening. With that said, the lock washers (split washers) I have used are not ideal, and would be considered second best to chemical locking compound (loc tite). I am going to keep the 6 new coffee can nuts used, and add loc-tite today. Will mark them with a paint pen and re-visit this at next oil change for any changes. For anyone installing rear axle shafts, you may wish to tack weld the 4 retainer bolts to the retainer plate prior to install (to prevent them from spinning down the road). I am hoping these G2 axles never need to come out and have fingers crossed they won't spin if I try to remove them.
