NHTSA recall 78V119000
Steering › Linkages › Knuckle › Spindle › Arm
Porsche 928
The defect
Both the left and right steering arm are attached to the front axle knuckle with two fastening bolts. These bolts are beveled below the hex head to fit into the chamfered holes in the steering arm for proper fastening. The chamfering in these steering arm holes was omitted during manufacture. Should the bolts loosen, the steering arm could become loose.
The remedy
The dealer will correct the defect by chamfering the holes.
