That spring isn't all that strong so I'd strong I'd expect you could push it up by hand. I'd air pressure test the servo itself before I disassembled it. If it air tests good with 35-50 psi of pressure that tells you it's fine. If you need a air pressure test chart here it is

It's kind of a PIA to get back in but I have taken them out by hand while in the car.

The only problem with air testing is most people don't know if what they are hearing when they pressurize something is normal or not.
The only way I can describe it to the OP is servo's leak almost no air when pressurized and clutchpacks do have some normal leak by due to the air having to go by sealing rings and such that do leak some air normally.
You or I would know right off, but someone who isn't familiar with it may not be able to tell what's normal.

Not to argue with ya Tracy, but in this case I feel a visual inspection of the servo piston and seal may be best if he can.
