A very useful wall chart identifying the proper torque specifications for truck and trailer wheel ends is available from Webb Wheel Products. Recommended specs are shown for 6- and 10-stud ball-seat-mounted and 8- and 10-stud pilot-mounted disc wheel hubs; 3-, 5- and 6-spoke wheels; and brake drum and rotor assemblies.

Webb, quite correctly, says having this information clearly visible in a maintenance shop can reduce wheel-end service times and help train new technicians. This chart is an important addition to any heavy truck and trailer maintenance facility and can be requested online or by calling 1-800-633-3256.
