WARNING:
Exceeding these ratings by overloading can cause component failure resulting in property damage, personal injury or death. |
Fluid Temperature
If the operating temperature exceeds
250 °F (121 °C), the rate of axle lubrication oxidation increases and shortens the life of the lubricant and seals, requiring axle lubrication changes to become more frequent to preserve the axle. Do not consistently run extreme pressure (EP) lubricants above
250 °F (121 °C).
Axle Conversions
WARNING:
When operating a loaded vehicle, the driver must keep all adjustable axles on the ground at all times, supporting their share of the vehicle’s load. Failure to do so can overload other axles, tires, wheels, springs, steering components, brakes and frames, resulting in early component failure, loss of vehicle control, possible property damage and personal injury. |
We do not recommend, or approve, performing axle conversions. However, we understand that, on occasion, others install aftermarket add-on axles on the truck chassis that allow operator control for weight transfer from other axles (such as air lift axles).
