84 trx 200 shifting/axle issues.

Hey guys I just picked up an 84 trx 200. Its got some issues so I thought I would join the forum to get some help and ideas on it. So the first problem is that it wont shift into neutral. When you move the shift lever it will usually pop shift into one gear, but it will only go up or down once. It wont shift into neutral. The shift lever seems to have a lot of play, I tried adjusting the free play and it did not really change the free play i it. I am planning on taking the clutch cover off to see if anything looks broken or worn. So anyone knows some things to look for and check out it would be greatly appreciated. The other issue is with the axle, I noticed a wobble when filling the rear right tire with air. I looked at the axle and it has a little gap in it, really close to where the tire mounts too. I will post some pictures to show what it looks like. I am not really sure what would cause that, maybe the nut just needs to be tightened more to close that gap. Thanks in advance for any help!
