Two grease outlet fittings are located on the front of each suspension cylinder. The grease supply line for the Auto Lubrication System is
located at the rear of the suspension cylinder. No grease outlet fittings should be located on the same side of the suspension cylinder as the
grease fill location. Having an outlet fitting on the same side of the suspension cylinder as the grease fill location will prevent proper
lubrication of the cylinder.
