WTF...mine has king pins and a straight axle!
No dealer is going to dismantle all of the suspension to determine if it was properly lubricated any more than Chevy or Ford is going to take a factory car apart before delivery to make sure everything is done correctly. And, that's what would have to be done to find out it was dry.
It's easy to say it's the dealers responsibility....It's another to make sure it's done unless you take the car apart at the dealer.
Maybe the factory ran out of grease the day my car was built
