Lubricant Type:
• Standard EP-SAE 90 wt. API GL-5. Lubricant temperature must never
exceed 250º F (+121º C).
To Drain:
• Place a suitable container below the bearing cover and remove the
drain plug. If the cover does not have a drain plug, remove the screws
retaining the cover plate to drain the lubricant.
• Replace plug or cover plate and fill bearing assembly with the
recommended lubricant.
Lubrication Maintenance Safety:
Maintenance for the system entails an adequate periodic lubrication of the front
axle components. Chock wheels for safety prior to accessing components
underneath the motorhome.
Lubrication of the front axle is critical in order to avoid premature wear of the
king pin assemblies and other components. Grease zerks are located at the king
pin assemblies (two on each side of the axle, upper and lower) and one grease zerk
on each end of the tie rod. These points require lubrication every six months or
5,000 miles with grease meeting NLGI #2 specifications.
NOTE:Use only a hand operated grease gun on the fittings.
Grease fittings for the steering system are found on both ends of the drag link
(the bar connecting the steering gear to the axle), and on the steering drive shaft
located between the steering wheel and steering gear. Correct wheel alignment
promotes longer tire wear and ease of handling while minimizing the strain on the
steering system and axle components. Use NLGI #2 Lithium soap base lubricant
for all steering linkage and brake components.
INSPECTION: Wheel bearings should be inspected for wear whenever
the hubs are removed from the front axle.
