FRONT SUSPENSION AND STEERING
Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Tighten castellated nut (3) to 36 ft. lbs. (50 Nm) torque
and continue to tighten as needed to insert new cotter
pin. Maximum torque is 50 ft. lbs. (70 Nm).
Tighten bolt (13) securing intermediate shaft to pinion to
155 - 215 in. lbs. (18 - 24 Nm) torque.
After replacing or servicing steering components, always
verify that an 1/8” gap exists between large hex of rack
extension and rack and pinion unit when steering is
turned fully to the right forcing passenger spindle arm
against front axle.
Set proper rack extension-to-rack and pinion unit clear-
ance. See “Spindle Contact with Front Axle” on page E -
19.
Install front wheels per WHEELS AND TIRES section
and lower vehicle per SAFETY section.
Check front wheel alignment and adjust if necessary.
See “Wheel Alignment” on page E - 5.

Check for proper rack extension-to-rack and pinion unit
clearance by first turning steering wheel fully to the right.
The rear spindle arm on the passenger side
must rest
against
the front axle (Ref Fig. 23). If it does not, all
adjustment is made at the rack ball joint (6) (Ref Fig.
22). Loosen jam nut (5) at rack ball joint and use wrench
to thread shaft of rack extension (7) further into rack bal-
ljoint. This will provide more travel for the steering wheel
to be turned to the right.
Fig. 23 Spindle Contact with Front Axle
With spindle arm resting against front axle, cut wire tie
(14) securing bellows (9) to rack and pinion unit (1) and
slide bellows away from rack and pinion unit to see large
hex of rack extension. An 1/8” gap should exist between
the large hex and the end of the rack and pinion unit.
Fig. 24 Checking Gap
Adjust, using an 1/8” thick washer as a gauge, by turn-
ing shaft of rack extension with wrench to create the 1/8”
gap. Tighten jam nut (5) to 35 - 45 ft. lbs. (47 - 61 Nm)
torque. Secure bellows to rack and pinion unit with new
wire tie (14).
