GENERAL
Two different manual steering gear units are used in
Jeep vehicles. Left hand drive models use a recirculating
ball-type gear (fig. 2K-1). Eight hand drive models use a
worm and roller-type gear (fig. 2K-2).
In the recirculating ball gear, the wormshaft and ball
nut are in line with the steering shaft in the column. The
ball nut is mounted on the wormshaft and is driven
through steel ball bearings which circulate in spiral
grooves machined in the wormshaft and ball nut. The
bearings act as a rolling thread between the wormshaft
and ball nut. The ball nut is directly engaged by the
pitman shaft teeth.

In the worm and roller gear, only the wormshaft is in
line with the steering shaft. The roller gear and shaft
assembly are mounted in a fixed position in the steering
gear. The three tooth roller gear is attached to the roller
shaft by a steel pin. The steering arm is attached
directly to the splined end of the roller shaft.
