Ram Axle Hub Nut Not Properly Crimped
This bulletin applies to 2020 Dodge Ram Promaster 2500 vehicles. The rear axle hub nut on a limited number of these vehicles may not have been properly crimped.
Verify proper axle nut torque, and if the nut has not been crimped, use a punch and hammer to crimp the nut to prevent loosening.
Examples: un-crimped nut (left) and crimped nut (right).
The staking must be in the opposite direction from forward rotation of the wheel.
