To add, when removing the swingarm, I’ll often additionally remove the wheel and sometimes the final drive to lighten the load, especially when trying to get the driveshaft to seat onto the transmission, but if you’re patient enough, you can get it all back on with the pumpkin and wheel still on. Helps to have the swingarm supported in the back by the shocks to free your hands and have the wheel in the air while you carefully play Line the Spline and Stick the Pivots.
