Purpose of the Part

The A13111T4804 connects the steer-axle beam to the wheel end while allowing the wheel to pivot when the driver turns the steering system. The kingpin passes through the knuckle/axle connection, while the steering and tie-rod arms transfer movement from the steering linkage into the wheel.

Issue Symptoms / When to Replace

A damaged or worn steering knuckle can contribute to excessive front-end play, poor alignment, uneven tire wear, or steering that will not hold adjustment. Cracks, damaged arm mounting points, worn kingpin bores, or damaged machined surfaces are reasons to inspect the knuckle closely. Kingpins, bushings, wheel bearings, tie rods, and steering arms can create similar symptoms and should be checked at the same time.

Brand Information

Cummins acquired Meritor in 2022, and Meritor-branded axle and brake products continue under Cummins Drivetrain and Braking Systems. A13111T4804 remains listed by Meritor as an active Genuine OEM front-axle steering knuckle.

Installation Notes

Use the axle-specific Meritor procedure for kingpin fit, steering-arm hardware, fastener torque, and end-play checks. Steering geometry and kingpin condition should be verified before the truck returns to service.

How to Identify an OEM Part

A genuine unit can be identified by the factory Meritor identification label on the knuckle and the permanent casting markings on the housing.
