Factory part number 6513128aa: a nut, right supplied by MOPAR. It is catalogued under Nuts & Washers > Nuts.
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.
Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it. Leaves our US warehouse in one to two business days, and shipping is free over $59.
