Put rear on stands and remove the wheel.
Use impact for removing the lower nut, but Ive done it with just T-handle and a hammer, put copper grease there when youre done.
Put jack under the arm and jack it up a bit.
For the upper bolt, use long socket, I remember it being 14mm, but not sure. 1/2" usually wont fit through but 3/8" should have no problem.
You could remove the plastic sleeve if there still isnt enough room, but do not drop the bold inside the frame.
The bolt should come out when there is no pressure on the shock, threads are only on the other side.
Look in the hole with light if you cant get the bolt out, loosen the rear subframe and nudge it until the bolt is lined with the hole.
Rest should be pretty straightforward.
