Easy Steer™ Kingpins—Axles With Unitized Wheel Ends
Note: This procedure applies to Easy Steer Plus™ MFS 10-2015-N and MFS 12-2015-N sealed front axles. Refer to the identification tag on the front of the axle beam.
On Easy Steer Plus front axles, the grease fittings are on the top and bottom kingpin caps of the knuckle.
- Shut off the engine, apply the brakes, and chock the rear tires.
- Make sure the tires touch the ground. Do not raise the vehicle.
- Clean off all grease fittings prior to lubrication.
- Using a multipurpose grease, NLGI grade 1 or 2, lubricate the kingpins through the grease fittings on the top and bottom of the knuckle. See Fig..
- Force lubricant into the upper and lower kingpin grease fitting caps until new lubricant flows from between the upper axle beam end and the knuckle, and between the lower axle beam end and the knuckle. See Fig..
- Remove the chocks from the tires.
Important: Meritor recognizes that industry trends are moving toward increased selection and usage of synthetic grease in vehicle maintenance. However, some seals are known to expand when in contact with synthetic grease. Consult your local Meritor representative for synthetic grease application references before using any synthetic grease when performing axle service and maintenance.
