DAMPER, Steering Additional service procedure steps before replacing the steering damper: Before istalling the steering damper to the vehicle, it is important to prime the new damper by 5 continuous compression ? extension stroke cycles by hand, each cycle consists of a full compression and a full extension stroke, without stops as fast as possible. Use large screwdrivers inserted in the bushings to aid in purging. This will allow you to stand on the lower screwdriver to hold the damper stationary and pump the rod end easier. Perform purge before installing NOTE: Hand purge to be completed in a vertical position with the base cup sticker end down toward the ground and the rod side facing up.See CSN V41 for detail procedure.
