HOw did you know yours was bad? I was told when I bought Disco that one of mine was bad but not sure of the signs... what were your signs it was bad?

 

Vibration at idle and on the throttle. And powerbrake the drivetrain. You see excessive movement, time for new ones. You will feel it all the time. Especially in the seat and pedals.

 

ok so similar to any cars ? I used to be in car business years ago and Id brake engine and little throttle and see if any movement in engine or bounce if bad... I have a rumbling and just a looseness is best I can feel... I was under truck before and after I rebuilt my drive shaft and could grab the front drive shaft and twist is back and forth (1/2" either direction) and hear a gears touching in the transfer case... drive shaft is solid, Im not as familiar with all wheel drives so not sure if this is normal play...
