Rear Axle and Suspension REAR AXLE AND SUSPENSION General Maintenance WARNING! Do not work on the vehicle without the parking brake set and wheels chocked securely. If the vehicle is not secured to prevent uncontrolled vehicle movement, it could roll and cause serious personal injury or damage to the vehicle. • Use wood blocks (4 in. X 4 in. or larger) against the front and rear surfaces of the tires. Be sure the vehicle cannot move. Your vehicle’s suspension, by design, requires a minimal amount of maintenance. However, suspensions in “over-theroad” operations require periodic inspection to ensure trouble-free performance. WARNING! Do not operate the vehicle if the U– bolts are not properly tightened. Loose U–bolts do not properly secure the axle to the suspension. This could cause loss of vehicle control and an injury accident. Loose U–bolts can also cause uneven tire wear and poor alignment. Preventive Maintenance WARNING! Failure to maintain the specified torque values or to replace worn parts can cause component system failure, possibly resulting in an injury accident. Improperly tightened (loose) suspension U–bolts can lead to unsafe vehicle conditions, including: hard steering, axle misalignment, spring breakage or abnormal tire wear. See the Fastener Torque Tables for proper torque specifications. CAUTION: Do not spray the suspension with chemical products or mineral oil; it can cause damage to the bushings. NOTE: Failure to follow these recommendations could void warranty. See the “Medium Duty Maintenance Manual” for further information on servicing the rear suspension. Visual Inspection For all vehicles, mandatory maintenance procedures include retightening of U–bolts and complete inspection. However, even with proper maintenance, many factors affect the ser- – 212 – PB1318 3/01 Model 330
Preventive Maintenance vice life of springs and suspension components, such as: fatigue, vehicle gross weight, type of load, road conditions and vehicle speed. It is important that U–bolts remain tight. Severe use of your vehicle can cause them to loosen faster. But all vehicles need to have their U–bolts checked and tightened regularly. Be sure someone with the proper training and the right tools checks and tightens the U–bolts on your Model 330. New springs “settle-in” after the vehicle's initial service, causing the U–bolts to become loose. After the first 500 miles (800 km) of operation, inspect the suspension periodically, as noted below: • Visually check for loose or missing fasteners, cracks in hanger or axle connection brackets. • Check that springs are centered in hangers and in good condition. • Check for cracks, wear marks, splits, or other defects on the surface of the spring. • Replace defective parts. Because repaired springs cannot be fully restored to their original service life, replace the complete assembly if cracks or other defects are detected. Rear Axle and Suspension • After replacement of any part or discovery of loose components, check the torque of all fasteners. Rear Axle Lubrication • Check oil level with the vehicle parked on level ground and the fluid warm. The level should be even with the bottom of the filler hole. CAUTION: Do not mix lubricants of different grades; although, mixing different brands of the same grade lubricant (meeting MIL–L–2105–C), is acceptable. Lubricants of different grades are not compatible and could damage the axle. NOTE: In all cases, the lubricant supplier assumes full responsibility for the performance of their product, and for product and patent liability. Initial Change: Change lubricant in new or rebuilt axle assemblies within the first 3,000 to 5,000 miles (4800 to 8000 km). For recommended types and brands of lubricants, contact your Peterbilt Dealer or Authorized Service Center. See the Medium Duty Maintenance Manual and the axle manufacturer’s Service Manual for further information on servicing drive axles. Model 330 PB1318 3/01 – 213 –
