1981 Gmc Brigadier

Component

Steering:Wheel And Handle Bar

Consequence of Defect

during assembly the upper steering column shaft pinch bolt may not have been sufficiently tightened. movement may occur between the upper steering shaft and the yoke, causing accelerated pinch bolt wear at the "whistle slot" in the shaft. pinch bolt wear could cause the yoke to slip from the shaft.

Corrective Action

Recall Notes

the dealer will inspect the upper steering column shaft to ensure proper tightening of the nut and bolt. if necessary, a new nut and bolt will be installed and properly tightened at no charge to owner.
