i went to replace the locking hubs on my 78 k20 and when i pulled the passenger side hub off i noticed that the axle shaft has play in it. i can move the shaft maybe a quarter inch in and out and side to side and up and down.. the driver side has no play in it at all.. i took the tire off and i can do the same thing if i play with it at both ends of the ujoint...
so does anyone have any idea what this could be?
