Still unsure on weather to change as not run the ZX5 yet as no electrics installed. i understand that the diffs in the durango are geared but what sort of maintenace do you need to do on them compared to say a ball diff???If any and also been reading that the ball cups need changing is that due to bad design or they just pop of very easy in a crash. Was a bit heavy handed with the pred so used to having to rebuild diffs etc, but want something easier as dongt have the time know to do all that sort of maintenace etc.
Any help advise is appreciated
Cheers
Windy
