2.5 DRAG LINK
Drag link assembly consists of three parts; a
drag link and two end assemblies. Both end
assemblies are identical and they are retained
on the drag link with a clamp bolt and nut.
Stud nuts at the pitman arm and bell crank ends
of the drag link must be kept tight or hole at ball
stud end of drag link and hole in pitman arm
may become enlarged as a result of excessive
looseness. Subsequent tightening of stud nuts
may draw studs too far into holes and dust cover
parts may become damaged which can result in
component failure.
Drag link end sockets are equipped with
lubrication fittings and should be lubricated as
directed in "Lubrication Fittings" in this Section.
2.5.1 Adjustment
It should not be necessary to alter the length of
the drag link except when a new link is installed
or when removable end assembly has been
replaced. If drag link adjustment is necessary,
proceed as follows:
1. Position front wheels in straight ahead
position.
2. Center steering gear as previously
explained in paragraph "2.2 Steering
Linkage Adjustment".
3. Remove cotter pin, nut and stud from drag
link at bell crank. Locate centerline of
vehicle and center of relay rod. With center
of relay rod aligned with centerline of
vehicle, loosen clamp bolt at socket end
(bell crank end) of drag link and adjust
length of socket end assembly to fit in boss
of bell crank.
NOTE
Do not change position of pitman arm.
4. Install stud with nut and torque to 150-200
lbf-ft (203-271 Nm). Align nut with cotter pin
slot (tighten) and install a new cotter pin.
5. Torque mounting clamp bolt nut to 40-60 lbf-
ft (55-80 Nm), then test the adjustment.
Front wheels should turn from right to left
extremities without noticeable binding at
drag link ends.
2.6 BELL CRANK AND IDLER ARM
Bell crank and idler arm are equipped with one
lubrication fitting and should be lubricated as
directed in paragraph "2.10 Lubrication Fittings"
at the end of this Section.
2.6.1 Bell Crank and Idler Arm Removal
NOTE
Use a piece of wire to anchor loosen end of
relay rod and tie rod in order to prevent
placing an excessive load on opposite socket
end.
Bell crank: Disconnect drag link, tie rod and
relay rod from bell crank by removing cotter pins
and nuts from ball studs. Separate socket
assemblies from the bell crank.
Idler arm: Remove cotter pins and nuts from
ball studs connecting relay rod, tie rod and
hydraulic power cylinder to idler arm. Separate
socket assemblies from idler arm.
Remove nuts from bolts attaching bell crank or
idler arm mounting spindle to suspension
subframe. Remove bell crank or idler arm
mounting spindle.
2.6.2 Bell crank or Idler Arm Ball Joint
Disassembly
1. Remove adjacent link assemblies from bell
crank or idler arm as previously described.
2. Remove the cap (Fig. 11).
3. Remove the cotter pin, nut and thrust
washer. Remove bearings, grease retainer,
backup ring and the bell crank or idler arm
from its mounting spindle (Fig. 11).
2.6.3 Bell Crank or Idler Arm Ball Joint
Reassembly
