Steering recalls for the 1978 Mack RD
- The problem
- An improper pinch bolt and nut may have been used in the clamping of the steering shaft to the steering gear input shaft. Due to clamping force loads applied at the bolt, the nut could yield, resulting in looseness of the input shaft yoke. Should this condition go unnoticed, spline wear could cause shaft separation.
- The fix
- Vehicles will be inspected and, if necessary, the correct fasteners will be installed at no charge to owner.
- The problem
- The existing cross steering arms may have insufficient fatigue life in the neck area. This is near the boss for the cross steering tube ball joint connection. Failure of either of the cross steering levers could lead to loss of steering control of the right front wheel.
- The fix
- The dealer will inspect and, if necessary, install cross steering arms of improved design and greater strength.
