Future Keystone purchasers pay attention here.
Thank you . Glad im not the only one.
Sorry to the OP for having this issue , I hope it all works out for you.
..... the network of dealers are banging their heads against the wall and are fed up too .
It makes it kind of difficult for the dealer to take care of the customer when the Mfg, shrugs them off as well . Some dealers have to go into their own pocket to help a good repeat customer find a resolution .
IMO, very good advice as suggested , go to a reputable axle shop to install a better component than O.E.M. Why put in the same to break again .
