if it is not a live axle what would cause the slack by grabbing the wheel?
The 8.25 is a live axle,just not a full floating axle.The 8.25 uses axle bearings to support the axles and the axles bear the weight of the vehicle and tranfer power.In a full floating axle(like the C14 bolt) the axle has a spindle on the end of it in which there are wheel bearings that support the weight of the vehicle and the axle only transfers power and does not support any weight.
If you have slop in the ends of a 8.25 you have bad axle bearings or loose lugnuts.If there is slack by pulling straight out and in then you have a worn center pin in the carrier.
