Factory part number 68019846AA: an o ring supplied by MOPAR. It is catalogued under Nuts & Washers > Rings & Retainers.
A lock nut and a plain nut are not substitutes on a steering or suspension joint, and a wave washer holds preload rather than merely spreading load.
The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. In stock and sent from the US in one to two business days, free delivery over $59.
