Steering Linkage
Note: Greasable drag links are also available as an op-
tion.

Lubricated the tie rod.
TRW steering gears have a seal at the sector shaft that
needs greasing with a hand gun every 4 months or
more often if the weather and road conditions are severe.
Sheppard steering gears have seals at input shaft and at
the sector shaft that need greasing with a hand gun ev-
ery 4 months or more often if the weather and road
conditions are severe.
No axial movement is allowable when 100 lbs. of hand
pressure is applied. Use hand pressure only, do not
check using pliers, wrenches or any other tools.
For all VHD Axle Back models, the steering shaft U-
joints should be inspected to see that the plastic caps
are intact. Complete this inspection every 4 months. A
shorter inspection period interval may be required if the
vehicle is operated under severe driving conditions.
For VHD Axle Forward models, grease the steering shaft
U-joints every 4 months. A shorter maintenance interval
may be required if the vehicle is operated under severe
driving conditions.
Brake Cams
Note: Meritor systems have special brake lubrication
requirements. Refer to proper literature in Function
Group 5.
There is one grease fitting on each cam for front and
rear wheel brakes. Fill with grease until old grease is
forced out past the end seal and only uncontaminated
grease is visible.
Note: Parking brake should be released so grease
can penetrate properly throughout the brake cam.
