Tie Rod Lubricating

For any Detroit or Meritor axle that requires lubrication of the tie-rod ends, wipe the grease fittings clean, then pump multipurpose chassis grease, NLGI Grade 1 (6% 12-hydroxy lithium stearate grease) or NLGI Grade 2 (8% 12-hydroxy lithium stearate grease), into the tie-rod ends until all used grease is forced out and fresh grease is seen at the ball stud neck. See Fig.Grease Fitting and Boot (Detroit axle shown).

Note:  No grease should emit from the tie-rod boot. If grease emits from the tie-rod boot, the boot is damaged.
