Does the rear axle nut on a '90 have a shoulder at the base - mine doesn't? How thick is the separate washer? '90/'91 use a cotter pin to retain the nut (castellated nut - think tie-rod ends) and the cotter pin hole in my axle is ~1/8" outboard of the nut so there is no engagement of the cotter pin what-so-ever. I'm thinking somebody swapped the nut with an off the shelf castellated nut. Will a later model 'locking' rear axle nut work on my '90?
