Front Wheel Alignment
The front wheels should be adjusted with
zero to 1/8" toe-in measured 10" from the
ground. This adjustment is made by loosen-
ing the clamp bolts on the tie rod ends and
turning the tie rod in a clockwise direction, as
viewed from the right, to increase toe-in, and
in the reverse direction to reduce toe-in.
A special tool is required to make this
measurement accurately. This adjustment is
important for correct steering to prevent ex-
cessive tire wear. Have your Authorized
Hudson dealer check this alignment fre-
quently.
Caster
The caster (backward tilt of the axle) should
be from 1° to 2° and should be equal within
1/2° at both front wheels.
To increase caster proceed as follows:
1. Loosen upper bolt (A), Figure 53.
2. Remove lower bolt nut and lock washer (B) and withdraw bolt.
3. Install shim at location (C). (Shims are .020" thick and equal to 1/2°.)
To decrease caster proceed as follows:
1. Loosen upper bolt (A).
2. Remove bolt nut and lock washer (B), and withdraw bolt.
3. Remove shim at location (C).
Note: Whenever caster setting is changed it is necessary to readjust the steering gear to the
high point setting. See page 58.
Camber
The camber (outward tilt of front wheels) should be from 1° to 1½°.
Should any front axle parts become bent, through accident, to such extent that they cannot
be straightened without heating, they should be replaced with new ones. Heating will destroy
the original heat treatment of the parts and may result in sagging or even breakage.
REAR AXLE
The rear axle, Figure 54, is of the semi-floating type carried in a one-piece, welded,
banjo-type housing. This gives a rugged assembly, with all parts readily accessible, as the
axle shafts and wheel bearings can be removed without disturbing the differential assembly;
also the differential and gear set assembly can be removed as a unit, after the axle shafts have
been removed, by simply disconnecting the rear universal joint flange and removing the eight
carrier bolt nuts.
