If you are trying to change the boot over the U joint at the swing arm, you don't need to remove any shaft to do that. You do however have to remove the swing arm.

if 4th gear is the only gear not grinding then there is a problem in the counter shaft bearings in the box
in reality there is no 4th "gear" as it is a straight through connection of the input and out put shafts and there is no load placed on the counter shaft set bearings
obviously you do not have a manual and that will cause you big problems in reassembly. however yo will have to remove the output shaft first. remove the circlip behind the rear bearing of the output shaft. tap the out put shaft towards the front of the box until it is free of the bearing. use a drift to knock the bearing backwards out of the box. this should allow you to then remove any circlips and remove the shaft from the gears
Get your self a manual as it will explain all the details
If the clutch is operating fine as well as the shift mechanism, it's either a bearing or a internally cracked case that's allowing the bearing to move. First gear is actuated on the rear transmission shaft that Is common to the drive sprocket on the left side of the bike, and an idler gear that engages the kick start lever to the clutch basket. This is located under the right engine case cover. Remove the chain and sprocket and check the shaft to see if it will move up and down in the bearing. If that's solid, remove the right side cover and check the case and bearing under the idler gear. I have had Yamaha cases crack at that bearing area and cause that same problem. Good luck!
Hi That sounds like the bevel box gears at the rear wheel or the drive shaft to them Pull back the rubber boot at rear of engine to check if shaft is rotating remove rear wheel & check the output shaft from the bevel box is rotating If not then remove bevel box & check splined join to drive shaft
remove upper and lower ball joints and tie rod. remove backing plate. hold on to axel and pull hard and quickly. inner joint will pop out of differential. hold axel in vise .if replacing outer cv boot you must first remove inner boot. remove boot clamps first on inner boot. pull boot back out of the way. hook and remove clip on inside of cv joint outer cup about 3/16 of an inch in. pull joint apart. remove grease at end of shaft to find snap ring clip. remove clip. pull off joint and remove boot. outer cv joint does not come apart.
