  7. Pivot the shock absorber and washers on the lower stud.
  8.  
  9. Remove the shock absorber and washers from the lower stud.
  10.  
  11. Installation is the reverse of removal. Purge the new shock of air by extending it in its normal position and compressing it while inverted. Do this several times. It is normal for there to be more resistance to extension than to compression. Torque the nuts to 60 ft. lbs. (81 Nm).
