Bearings – How often should I grease the bearings?
Along with bearing adjustment, proper lubrication is essential to the current function and reliability of your trailer axle. Bearings should be lubricated every 12 months or 12,000 miles. Oil bath axles should be checked on each trip through the sight glass.
Bearings – What is the proper bearing adjustment procedure and recommended grease (9K-15K)?
Please review the axle service manual for instructions and specifications relating to bearing adjustment and lubrication.
WARNING: It is important to NOT mix different types of grease thickeners. The grease that the axles use has a lithium complex thickener. Mixing the grease with a barium, calcium, clay, or polyurea soap based thickener agent will cause adverse effects. This may include causing the two greases to harden, separate, become acidic or pose other hazards and damage to the bearings.
