Hendrickson

The Hendrickson RS Series suspension does not require lubrication.

For Hendrickson RT2 and RTE2 Series, lubricate the bronze, ball-indented bushings in the spring eye, as follows:

  1. Park the vehicle on a level surface, apply the parking brakes, and chock the front tires.
  2. Raise the rear of the vehicle until the rear wheels are suspended in the air, then support the vehicle with safety stands. This relieves the load on the bushings and pins to allow the proper flow of lubricant around them.
  3. Use a multipurpose chassis grease and lubricate the bronze, ball-indented bushings in the spring eyes at the grease fitting; see Fig.. Continue to lubricate until grease exits both ends of the bushing. If the pin will not accept lubricant, remove the pin and clean the lubrication channels where lubricant may have hardened. Lower the vehicle and remove the safety stands.
