So the mast of the lift pivots around the differential (blue circle in picture below), I'm guessing that if you pull the bolts (circled in red, and the blind ones you cannot see that have studs accessed from behind) the mast becomes unsupported). So i will have to move my wood dunage back to the frame behind the wheels to support it.

I'm wondering if i do one side at a time if i can get away with leaving the mast connected, and not having to worry about taking the thing totally off the tilt rams, and the hoses for the main ram.

If i do find the shoes or wheel cylinders are bad, what are my chances of getting replacement parts?
