94 Ram Steering Gear Adjustments
Instructions from the 1994 Ram Service Manual
STEERING GEAR REPLACEMENT
Mark pitman shaft and pitman arm for reassembly reference. Remove pitman
arm from shaft with puller C-4150A (Fig 4).
Remove steering gear retaining bolts and nuts, and remove steering gear
Place front wheels in straight ahead position
Disconnect and cap power steering hydraulic hoses
Remove coupler pinch bolt at steering gear and slide shaft off gear (Fig
NOTE: keep your fingers from inside the steering
wheel when the engine is started and as air is purged from the lines. A
failure in the system can spin the steering wheel with enough force to
break fingers and dislocate thumbs. - Dave
Position the steering gear on the frame rail and install the bolts. Tighten
mounting bolts to 140 ft-lbs (190 Nm).
Align steering coupler on gear shaft. Install pinch bolt and tighten to
36 ft-lbs (49 Nm).
Align and install pitman arm.
Install the washer and retaining nut on the pitman shaft. Tighten nut to
185 ft-lbs (251 Nm).
Connect fluid hoses to steering gear, tighten to 23 ft-lbs (31 Nm). Add
fluid, refer to Power Steering Pump Initial Operation.
Steering Gear Adjustments
CAUTION: Steering gear must be adjusted as outlined.
Failure to adhere to the procedure may result in gear damage or improper steering
Remove the gear by following the instructions
above, and mount it in a vise. Drain the power steering fluid and make
the following adjustments in order:
Worm Thrust Bearing Preload Adjustment
FIRST - worm thrust bearing preload
SECOND - over-center preload adjustment
Turn the adjuster in with spanner wrench C-4381. Tighten the plug
and thrust bearing in the housing until firmly bottomed in housing.
Place an index mark on the housing even with one of the holes in adjuster
plug (Fig 6).
Measure back (counterclockwise) 13 mm (0.50") and mark housing (Fig7).
Rotate adjustment plug back (counterclockwise) with spanner wrench until
hole is aligned with the second mark (Fig 8).
Install and tighten locknut to 80 ft-lbs (109 Nm). Be sure adjustment plug
does not turn while tightening the locknut.
Remove adjuster plug locknut (Fig 5).
Turn the pitman shaft adjuster screw back (COUNTERCLOCKWISE) until extended,
the turn back in (CLOCKWISE) one half turn.
Place the torque wrench in the vertical position on the stub shaft. Rotate
the wrench 45 degrees each side of center and record the highest rotational
torque on center (Fig 10).
Turn the adjuster in until torque to turn the stub shaft is 6.0 to 10.0
in-lbs (0.6 to 1.2 Nm) more than the reading recorded in step 4.
Prevent the adjuster screw from turning while tightening the lock nut.
Tighten the adjuster lock nut to 43 ft-lbs (58 Nm).
Rotate stub shaft from stop to stop and count the number of turns.
Starting at either stop, turn the stub shaft back 1/2 the total number
of turns. This is the center of the gear travel. (Fig 9).
GEAR DISASSEMBLY INFORMATION
CAUTION: Cleanliness is extremely important when repairing a power steering
gear. Keep the bench, tools, and components clean at all times. Thoroughly clean
the exterior of the steering gear with cleaning solvent before disassembly.
Drain as much of the fluid as possible. Use protective vise jaws at all times
when clamping components. During assembly, lubricate all components with power
steering fluid except when instructed otherwise (Fig 11)
