Recall 79V-130: 1978–1979 Mack RWL, 1978–1979 Mack RWS

The problem

It has been determined that two screws that are part of the bearing assembly located at the cab dash sheet may not have been tightened properly. As a result, the upper steering shaft may be free to "float" throughout much of its length which may result in inadequate engagement in the slip splines of the lower steering shaft. Axle articulation could result in disengagement of the lower steering shaft slip splines.

The fix

Dealer will install a sleeve between the dash sheet bearing and the upper steering shaft lower yoke to assure positive upper steering shaft location.
