torque of 300 lbf·ft (406 N·m). If the steering arm
bolt torque has fallen below this specification,
remove the bolt, clean all the threads, and apply
new Loctite
® 680. Tighten the bolt 300 to 450

33–03 Tie Rod End Lubricating
This procedure applies to all tie rod ends on Meritor
nondrive steering axles.
1. Park the vehicle with the wheels in the straight-
ahead position. Turn off the engine, apply the
brakes and chock the rear tires.
2. Wipe the zerk fitting and the seal or boot clean.
NOTE: Synthetic lubricants are not approved for
tie rod end lubrication.
3. Using a grease gun, apply a multipurpose
grease, NLGI grade 1 or 2, to the zerk fitting until
all the old grease is purged from the boot. Dis-
colored old grease should come out of the purge
holes near the boot crimp or bellows area.
Apply grease until all the old grease is purged
from the boot.
NOTE: If using an air pressure grease gun, do
not exceed 150 psi (1035 kPa).
4. If the tie rod end is designed for lube service and
it does not accept grease, perform the following
substeps.
4.1 Remove the zerk fitting.
4.2 Inspect the threaded zerk fitting hole in
the tie rod end and remove any obstruc-
tions.
4.3 Install a new zerk fitting.
4.4 Apply lubrication to the new zerk fitting.
5. Remove the chocks from the tires.
