Hello new to the forum and have a few questions, bought a 04 700 twin and when we drive it there is a clicking noise I think coming from the front drive shafts but when I put it in 4 wheel drive it goes away

Next the right rear tire has a slight toe in and seems to wobble when we drive it. I jacked up the back tires and there is not really any play in that wheel but the other side has some. There should not be any right? Also should the axle have play in it where it meets up to the gearbox?

Thanks!
