46–04 Power Steering Gear
Lubrication
TRW TAS and THP Series
Sector Shaft
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.

NLGI Grade 2 (8% 12-hydroxy lithium stearate
grease) or NLGI Grade 1 (6% 12-hydroxy lithium
stearate grease). Grade 2 is preferred.
