The Meritor Steering Tie Rod Arm is a forged steel tie rod arm that acts as the mechanical lever between the steering knuckle and the cross tube. This Meritor 3133Q7973 steering arm is engineered with a specific offset to maintain the correct Ackermann geometry, ensuring the wheels turn at slightly different angles for smooth, scrub-free cornering. The tapered mounting hole is precision-reamed to provide a wedge-fit with the tie rod end, eliminating the steering "play" or wandering that can occur with worn components. Replacing a stressed or damaged arm is vital for maintaining the vehicle's tracking and preventing the accelerated tire wear associated with misalignment.
