Lubrication

NOTICE

Apply grease to the sector shaft with a hand-type
grease gun only. Use of a high-pressure power
grease gun will supply grease too quickly and
could affect the high pressure seal, contaminating
the hydraulic fluid.

Using a hand-type grease gun, apply NLGI Grade 2
or 3 multipurpose chassis grease until it starts to
come out past the sector shaft seal. See

Fig. 2

46–05 Drag Link Lubrication

Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.

Using a clean rag, wipe all dirt from the drag link
grease fittings. See
