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.

My 93 ford f 150 5 speed well not engage into first or second and makes a windings sound but will engage in the rest of the gears

I suspect that the box will have to be rebuilt
1 st and 2nd gears place a side load on the main shaft and clutch shaft bearings and spigot bearing the end of the clutch shaft
3rd gear is more to the rear of the main shaft and is more supported by the rear main shaft bearing
4th gear is not a gear as such but a direct coupling of the clutch shaft and the main shaft
5 th gear is out side the main box in the extension housing
any noise will be from failing bearings
I suspect that the clutch shaft bearing and the spigot bearing will be the main problem with metal affecting the other bearings.

I have a 1996 Nissan XE pickup 2.4l.4cyl,4×4 5-speed. It grinds in all gears,even reverse except for 4th gear.. What's up???

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

How do i remove 2nd gear in mazda drifter 2.5 4x4 manual

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

Hello.Owner of 1990 XT600 2KF,30.000 km in very good condition. after een steep ride in first gear,I cannot shift to first gear.It seems stuck.Engine off: no problem changing gears. What can this be: Oil...

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!

When i put the bike into gear it will not move. You can hear grinding from the rear. Any ideas?

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
