To remove the idler arm (18) from the steering housing
assembly (13), remove the steering housing assembly
from the vehicle (as described above) (Ref Fig. 6 on page
J-5). Remove the cotter pin and nut (20) attaching the
steering rack ball joint (21) to the upper idler arm, remove
the lock nut (22) and the two washers (23, 24) from the
idler and remove the idler arm from the steering housing.
Replace idler arm in reverse order of removal.
Tighten nut (22) to 70 - 80 ft. Ibs. (95 - 110 Nm) torque.
Insert new cotter pin (25).
Tighten nut (20) to 35 ft. Ibs. (50 Nm) torque and continue
to tighten as needed to insert new cotter pin. Maximum
torque 50 ft. Ibs. (70 Nm).

Rack Tensioner Replacement
Tool List
Qty.
Wrench, 9/16” .............................................................. 1
In general, there is no need to remove the rack tensioner
(26) unless the rack bellows (27) and or the rack cover
(28) have been torn or damaged and there is reason to
believe that water or dirt has entered the housing (Ref
Fig. 6 on page J-5). The tensioner can be greased
through a right angle grease fitting (29) located on the
steering housing directly behind the front shield. The ten-
sioner does need to be removed in order to replace the
rack (30).
To remove the tensioner, remove the bolts (31), the cover
plate (32) and gasket (33) that secures the rack tensioner
in the steering housing. Remove the spring (34) and ten-
sioner.
Replace rack tensioner in the reverse order of removal,
replacing gasket (33) with a new one.
Tighten bolts (31) to 18 - 22 ft. Ibs. (25 - 30 Nm) torque.
Lubricate through grease fitting (29).
Rack Replacement
Tool List
Qty.
Wrench, 9/16” .............................................................. 1
Needle nose pliers....................................................... 1
Wrench 11/16” ............................................................. 1
Ball joint separator....................................................... 1
Plastic faced hammer .................................................. 1
Straight blade screwdriver ........................................... 1
The rack can be removed by loosening the tensioner
bolts (31), removing cotter pin and backing off nut (20) on
rack ball joint (21) until end threads of ball joint are pro-
tected (Ref Fig. 6 on page J-5). Using a ball joint separa-
tor as a lever, apply pressure to ball joint and tap nut with
plastic faced hammer to release ball joint from idler arm.
Remove nut from ball joint and ball joint from idler arm.
Remove the large clamp (35) that secures rack bellows
(27) to the steering housing. The rack and the bellows
may now be pulled from housing.
To test for straightness, lay smooth side of rack on the
edge of a metal straight edge in good condition. If a .015"
(.381 mm) feeler gauge passes between the rack and the
straight edge, the rack is excessively bent and must be
replaced.
The rack and steering pinion must be
replaced as a set.
Rack replacement is the reverse order of removal. Pull
rack into steering assembly by turning steering wheel.
Rack Ball Joint Removal
For rack ball joint replacement, the rack must be removed
from the steering assembly in order to properly adjust the
rack/ball joint length. (See above for rack removal). The
rack end ball joint (21) can be removed from the steering
rack (30) once the rack is removed from the steering
housing by loosening the jam nut (36) and removing the
ball joint (21) from the rack.
Rack Ball Joint Installation
Clean threads. Apply primer (LOCTITE LOCQUIC
PRIMER T, #7471) and thread locking adhesive (LOC-
TITE RED #271) to rack ball end before attachment to
steering rack. The ball joint (21) and jam nut (36) should
be threaded into the rack until the dimension between the
end of the rack and the center of the ball joint stud is 14 7/
32” (37.7 cm). Tighten the jam nut (36) to 25 - 30 ft. Ibs.
(35 - 40 Nm) torque.
See 'Rack Replacement' above for installation of rack into
steering housing.
