on a DD yes..i grenaded many a selectable hub ,mostly the drivers side when JR was a daily.every six months was the norm.it still broke one occasonaly with the standard hubs. warn premiums{sp} are the chit. and good deal highrider88.You're talking about drive flanges i think and in order to be able to run a selectable hub in the "free" mode you would have to install a part time kit in the 203 or keep the hubs locked.
i paid $100.00 each for mine.my 44 is from a 72.it used to be in this k20.i think his upgrade was slightly stronger.
