* Specific Bearing Type and Size: Freightliner Columbias used different bearing sizes and types over the years. The bearing's part number is crucial for finding the correct torque.
* Nut Type: The type of nut (e.g., flange nut, castle nut) affects the torque specification.
* Manufacturer's Specifications: Always consult the official Freightliner service manual or the bearing manufacturer's instructions for the precise torque value. These manuals will provide the most accurate information for your specific truck and components.
Where to Find the Information:
1. Freightliner Service Manual: This is the most reliable source. The manual will have detailed specifications for your specific model year and axle configuration.
2. Bearing Manufacturer's Documentation: The bearing itself or its packaging might have torque specifications.
3. Freightliner Parts Dealer: A Freightliner dealer can access the correct specifications using your truck's VIN.
Warning: Using the wrong torque can severely damage the bearing, potentially leading to wheel failure and serious accidents. Do not guess or rely on internet forums for this critical information. Always consult the correct service manual or a qualified mechanic.
