I. DESCRIPTION & OPERATION

A. General Description

The Fabco Steerable Drive Axle consists of four

major assemblies. The axle housing is the structural

backbone. Steerable drive ends are attached to each

end of the housing. A differential carrier assembly

bolts into the center of the housing. A steering con-

necting tie rod joins between the right and left steera-

ble drive ends. A steering arm is provided (usually on

the left steerable drive end) for connection into a vehi-

cle’s steering system. It may be equipped with right

hand or dual steering arms.

B. Operation

Driving forces are put into the axle at the pinion

yoke on the differential carrier; they pass through the

differential to the inner axle shafts and the inner drive

yoke of the universal joint; they then pass into the

outer drive yoke and the outer axle shaft which con-

nects to the wheel hub and rotates the wheel.

When steered, the outer section of each steerable

drive end turns about the kingpin centerline. The uni-

versal joint, centered on the kingpin centerline, allows

driving forces to turn with the steered wheel ends.

The axle is equipped with air or hydraulic brakes.

The brake shoes expand to contact conventional

brake drums.

C. Operating Instructions

In conditions where the vehicle’s rear wheels might

spin, such as sand, loose dirt, mud, snow, ice or

ascending grades, the front drive axle can be shifted

into operation for improved traction. Engagement can

be made at any vehicle speed, unless the rear wheels

are spinning. Engagement is best accomplished

while the engine is pulling lightly.
