Front Axle and Suspension Preventive Maintenance FRONT AXLE AND SUSPENSION Inspection For all vehicles, mandatory maintenance procedures include retightening all U–bolts and inspecting the suspension for loose fasteners, abnormal wear, or damage. However, even with proper maintenance, the service life of leaf springs is affected by many factors, such as: fatigue, vehicle gross weight, type of load, road conditions, and vehicle speed. SPRING AND SHACKLE PINCH BOLTS SPRING ANCHOR PINS • Check for cracks, wear marks, splits, or other • ects on the surface of the spring. Defective parts must be replaced. Because repaired springs cannot be fully restored to their original service life, replace the complete assembly if cracks or other defects are detected. • Visually inspect shock absorbers and rubber bushings. See the Medium Duty Maintenance Manual for further information on servicing the front suspension. Front Suspension Axle Lubrication SPRING ANCHOR PIN U-BOLTS 00439 • Change bearing lubrication when seals are replaced, or brakes are relined. See Table 1, “Recommended Maintenance Intervals,” Page 154. – 246 – Y53-6027 Medium Duty (R05/09)
Preventive Maintenance • Thoroughly clean hubs and bearings with solvent and a stiff bristle brush, then dry and inspect components for wear or damage. Re-lubricate with approved axle lubricant. Front Axle and Suspension KINGPIN (TOP) Kingpin Lubrication • Lubricate with approved lubricant. Lubricate knuckle thrust bearings, knuckle pins, and tie rod ends. See Table 1, “Recommended Maintenance Intervals,” Page 154. Lack of lubrication causes premature wear and hard steering. Lubrication schedule may be shortened if necessary. Suspension Lubrication Each spring anchor pin has a grease fitting. Pressure lubricate spring pins according to Table 1, “Recommended Maintenance Intervals,” Page 154, using EP chassis lube with 12-Hydroxy Lithium Stearate Base NLGI-2 with 3% molybdenum additive (e.g. Mobil-grease EP or equal). Front Axle KINGPIN (BOTTOM) 00445 • At regular intervals, the spring leaves may be lubricated with a rust-inhibiting oil applied with a spray gun or brush. • Lubricate all spring pins until grease flows out of both ends of the bushing. Look for signs of rust or water in the flushed grease. If a pin will not accept grease, it should be removed, cleaned, and inspected. Medium Duty (R05/09) Y53-6027 – 247 –
