Actually, the driver's side has both. I can move it in a circle and in and out of the diff slightly. Passenger side is radial only for now and isn't as bad. Wheel side is fine on both. You raise a good point about the seals potentially failing due to this. Might hafta check them out. I hate doing things twice. [emoji106]If your axle has radial play at the differential then chances are your seals aren't too happy either. Two kinds of shafts play scenarios - axial and radial. Which kind of play do you have?
I have 320xxx miles and I have zero axial and radial play at the diff end of both axles. Both axles are non OEM variety so I'm not sure what you got going on there.
