13.6 DRAG LINK MAINTENANCE
Visually inspect drag link components for
broken, corroded or deformed clamps, loose,
bent or corroded nuts and gauges on tube from
rubbing parts.
On vehicles equipped with I-beam front axle, the
drag link features lubricated for life ball joints
and a compact fine adjustment system.
Although the ball joints do not require greasing,
they do require regular inspection, refer to the
following sections for ball joint maintenance.
Adjustment System Visual inspection
Inspect the adjustment system to ensure the
threads are firmly seated. Also, a visual
inspection should be carried-out looking for
damage or corrosion to the adjustment system
components. Replace any part showing
corrosion or damage.
Adjustment System Functional inspection
Clean the adjustment system with a brush and
compressed air prior to inspection, if required.
With the engine running and the vehicle on the
ground (with a load on the axle) turn the steering
wheel left and right.
To verify that the threads are tight and do not
present any play, use one of the following
methods:
• Visual inspection
• Place a finger on the separation line from
the adjuster sleeve to the threaded ball
joint shaft.
Keep fingers clear of pinch zones.
• Use a dial gage clamped to the tube and
feelers aligned on the ball joint to indicate
any play
When play is discovered in the adjusting
system, replace the complete drag link.
CAUTION
Do not re-use clamp hardware.
Bolt and nut should be replaced every time
they are unscrewed.
While assembling the clamp, make sure
the bolt does not touch the draglink tube.
