grease, NLGI Grade 2 (8% 12-hydroxy lithium stear-
ate grease), until new grease is seen at the bushing
grease seal opposite the fittings. The grease seal will
accept grease pressure without damage, and is de-
signed to have grease pumped out through it during
lubrication. Even if grease leaks out around the top,
or bottom-plate gasket, continue pumping until new
grease is seen at the bushing seal opposite the
grease fitting; see
Fig. 4 .
NOTE: For operation in very cold climates, use
NLGI Grade 1 (6% 12-hydroxy lithium stearate
grease).
33–02 Tie Rod Inspection
IMPORTANT: If the tie rod end boot is torn or
missing, replace the entire tie rod end. Do not
replace the boot only.
1. Shut off the engine, apply the brakes, and chock
the rear tires.
2. Check the tie rod boot for cracks, tears, or other
damage. If the tie rod boot is damaged, replace
the entire tie rod end.
3. The threaded portion of the tie-rod end assembly
must be inserted all the way into the cross-tube
split for adequate clamping. See
Fig. 5 . Replace
the components if this cannot be done. For in-
structions, refer to
Group 33 of the 108SD and
114SD Workshop Manual .
4. Grasp by hand (or use a pipe wrench with jaw
protectors to avoid gouging the cross tube) and
slightly rotate the cross tube toward the front of
the vehicle and then slightly toward the rear.
