The sleeve is there to take up the manufacturing tolerances in the axle. In your case it is a zero degree shim which has no alignment adjustment.
To adjust you replace the ball-joint and then tighten the sleeve with the proper tool to 50 ft/lbs. Then you install the upper ball-joint nut and tighten to factory spec.
Once set, there is no further adjustment necessary. If the ball joint wears to the point of the sleeve no longer tight (slop in the joint) then the joint has reached the end of its service life and needs to be replaced.
