To verify that the threads are tight and do not
present any play, use one of the following
methods:
ï‚· Visual inspection
ï‚· Place a finger on the separation line from the
adjuster sleeve to the threaded ball joint
shaft.
Keep fingers clear of pinch zones.
ï‚· 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.

MAINTENANCE
Tie rod ends (ball joint) are provided with
grease fittings for pressure lubrication. These
grease fittings should be serviced at the
intervals specified by the Lubrication And
Servicing Schedule in Section 24:

To prevent corrosion from forming around the
ball pin, remove the old grease bead and
assure sufficient grease is applied to purge
the old grease and fill the joint and dust seal.
Good quality lithium-base mineral grease NLGI
No. 2 like Shell Retinax LX is recommended.
