83 245 M46 -All rear bushings have been replaced except the track rod bushings. New springs and shocks. New U-joints on the driveshaft. All engine/trans mounts are good.

I've been reading the archives about this knock and play sound in my rear axle on take off or when applying the gas after coasting. After putting the rear of the car on jacks and turning the wheels I can tell that its got something to do with the rear axle. I don't seem to get the play in the wheel like you would on the front. I can't move them when checking play at 12/6 or 3/9. When I turn the rear drivers wheel it sounds not right with the wheel in the air.

Can a rear wheel bearing cause a knocking sound with the feeling of some play at take off?

Can I just swap out the hub from a parts car with the same rear axle. I'm certain the 86 parts car has the same axle. Does the hub have the bearing contained inside of it. Can I swap hubs without replacing the bearings? Looking for a quick way with minimal cost to see if the bearings are the issue or if the rear axle is going to need replacing.

Thanks
