Claim:
1. A method for assembling a monotube shock absorber comprising: inserting a floating piston and a fixed valve assembly in a tube such that the floating piston is between the fixed valve assembly and a first end of the tube to define a gas chamber between the floating piston and the first end of the tube; rigidly affixing the fixed valve assembly to the tube; adding a first amount of a hydraulic fluid into the tube from a second end of the tube that is opposite to the first end such that the hydraulic fluid covers a side of the fixed valve assembly that is opposite to the floating piston; advancing a plunger into the tube from the second end to push less than an entirety of the first amount of the hydraulic fluid through the fixed valve assembly and into contact with the floating piston to push the floating piston to a first distance away from the fixed valve assembly thereby defining a compensation chamber between the fixed valve assembly and the floating piston filled with the hydraulic fluid; adding a second amount of the hydraulic fluid into the tube from the second end; inserting a rod guide assembly into the tube from the second end with both a piston rod and a piston assembly coupled to the piston rod, as the rod guide assembly is inserted the hydraulic fluid passes through the piston assembly to occupy a gap between the piston assembly and the rod guide assembly and the hydraulic fluid is further pushed through the fixed valve assembly into the compensation chamber to move the floating piston to a second distance away from the fixed valve assembly and further towards the first end; and charging the gas chamber through an opening to the gas chamber.
