steering DODGE RAM SRT-10 2006 Service Workshop Manual

FLOW AND PRESSURE TEST
1. Check the power steering belt to ensure it is in good condition and adjusted properly.
2. Connect pressure gauge hose from the Power Steering Analyzer to adapter6826.
3. Connect tube 6825A to Power Steering Analyzer test valve end.
4. Disconnect the high pressure hose from the power steering pump.
5. Connect the tube 6825A to the pump fitting.
6. Connect the power steering hose from the steering gear to the adapter 6826.
NOTE: If fluid leaked from the steering system, it should be filled to correct lervel prior to starting the
engine.
7. Open the test valve completely.
8. Start engine and let idle long enough to circulate power steering fluid through flow/pressure test gauge and to get
air out of the fluid. Then shut off engine.
9. Check fluid level, add fluid as necessary. Start engine again and let idle.
10. Gauge should read below 862 kPa (125 psi), if above, inspect the hoses for restrictions and repair as neces-
sary. The initial pressure reading should be in the range of 345-552 kPa (50-80 psi).
11. Increase the engine speed to 1500 RPM and read the flow meter. If the flowrate (GPM) is below specification,
(refer to pump specification chart for GPM) the pump should be replaced.
CAUTION: The following test procedure involves testing maximum pump pressure output and flow control
valve operation. Do not leave valve closed for more than three seconds as the pump could be damaged.
12. Close valve fully three times and record highest pressure indicated each time.All three readings must be
above specifications and within 345 kPa (50 psi) of each other.
Pressures above specifications but not within 345 kPa (50 psi) of each other, replace pump.
Pressures within 345 kPa (50 psi) of each other but below specifications, replace pump.
13. Open the test valve and turn the steering wheel to the extreme left and right positions three times against the
stops. Record the highest pressure reading at each position. Compare readings to the pump specifications
chart. If pressures readings are not within 50 psi of each other, the gear isleaking internally and must be
replaced.
CAUTION: Do not force the pump to operate against the stops for more than 2 to3 seconds at a time
because, pump damage will result.

DESCRIPTION
DESCRIPTION
NOTE: The steering column on vehicles with an automatic transmission may not be equipped with an inter-
nal locking shaft that allows the ignition key cylinder to be locked with the key. Alternative methods of lock-
ing the steering wheel for service will have to be used.
The tilt and standard column (1) has been designed to be serviced as an assembly; less wiring, switches, shrouds,
steering wheel (4), etc. Most steering column components can be serviced without removing the steering column
from the vehicle.
To service the steering wheel, switches or airbag, refer to Restraints andfollow all WARNINGS and CAUTIONS.
WARNING: The airbag system is a sensitive, complex electro-mechanical unit. Before attempting to diag-
nose, remove or install the airbag system components you must first disconnect and isolate the battery
negative (ground) cable. Then wait two minutes for the system capacitor todischarge. Failure to do so
could result in accidental deployment of the airbag and possible personalinjury. The fasteners, screws, and
bolts, originally used for the airbag components, have special coatings and are specifically designed for the
airbag system. They must never be replaced with any substitutes. Anytime anew fastener is needed,
replace with the correct fasteners provided in the service package or fasteners listed in the parts books.
CAUTION: Do not hammer on steering column shaft. This may cause damage to the shaft or bearing.
CAUTION: Do not attempt to remove the pivot bolts to disassemble the tilting mechanism. Do not remove
shaft lock plate or plate retainer. This will damage the column.
CAUTION: Do not attempt to remove or modify the park lock slider or link.
NOTE: When servicing the steering wheel after removing the old bolt, a new bolt must be used when install-
ing.
NOTE: When servicing the coupler a new bolt must be used when installing.

DESCRIPTION - SRT10
The SRT-10 column has noSTARTposition on the key cylinder. The push starter button switch is mounted on the
Instrument panel center stack. All SRT-10 columns are Tilt columns, Standard cab trucks come with manual trans-
missions, Quad cab trucks come equipped with automatic transmissions.
DIAGNOSIS AND TESTING
STEERING COLUMN
If the vehicle is involved in a front end collision/the air bag has deployedthe column must be inspected. This
inspection will determine if the Column has collapsed. Inspect the columnmounting capsules visually and manually
push and pull them to check for separation or fractures. If capsules are fractured or have moved the column MUST
be replaced.
REMOVAL
WARNING: Before servicing the steering column the airbag system must be disarmed. Refer to electrical
restraint system for service procedures. Failure to do so may result in accidental deployment of the airbag
and possible personal injury.
CAUTION: All fasteners must be torqued to specification to ensure proper operation of the steering column.
1. Position the front wheelsstraight ahead.
2. Disconnect the negative (ground) cable from the battery.
3. Remove the airbag, (Refer to 8 - ELECTRICAL/RE-
STRAINTS/DRIVER AIRBAG - REMOVAL).
4. Remove the steering wheel (1) with special tool
CJ98–1 (2) or an appropriate steering wheel puller.
(Refer to 19 - STEERING/COLUMN/STEERING
WHEEL - REMOVAL).
CAUTION: Ensure the puller bolts are fully
engaged into the steering wheel and not into the
clockspring, before attempting to remove the
wheel. Failure to do so may damage the steering
wheel/clockspring.

5. Remove the kneeblocker (2) and the steering col-
umn opening cover (1) (Refer to 23 - BODY/IN-
STRUMENT PANEL/STEERING COLUMN
OPENING COVER - REMOVAL).
6. Remove the screw (1) securing the tilt lever knob
(2).
7. Remove the column shrouds (1&2).

8. Remove the clock spring, (Refer to 8 - ELECTRI-
CAL/RESTRAINTS/CLOCKSPRING - REMOVAL).
9. Disconnect the wiring harness (8) to the column.
10. Remove the shift cable (5) from the column shift
lever actuator (4) (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 32RH/GEAR SHIFT
CABLE - REMOVAL).
11. Release the shift cable (5) from the column
bracket (7) and remove it from the bracket.
12. Remove the upper steering shaft coupler bolt (2).
13. Separate the shaft from the coupler (3).
14. Remove the brake light switch (2) and discard
(Refer to 8 - ELECTRICAL/LAMPS/LIGHTING -
EXTERIOR/BRAKE LAMP SWITCH - REMOVAL).
15. Remove the four steering column mounting nuts
(1 & 3).

16. Remove the steering column assembly (6) from
the vehicle.
17. Disassemble or transfer any components to be
replaced.
INSTALLATION
WARNING: Before servicing the steering column the airbag system must be disarmed. Refer to electrical
restraint system for service procedures. Failure to do so may result in accidental deployment of the airbag
and possible personal injury.

NOTE: Torque the upper left nut first then the
lower right nut. Then torque the lower left nut then
the upper right nut.
NOTE: A new bolt must be used for reinstallation.
5. Tighten the coupler bolt (4) to 57 Nꞏm (42 ft. lbs.).
6. Install a new brake light switch (2) (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/BRAKE LAMP SWITCH - REMOVAL).

7. Install the shifter cable (5). (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - 32RH/GEAR
SHIFT CABLE - INSTALLATION)
8. Connect the wiring harness (8) to the column.
9. Install the clockspring (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - REMOVAL).
10. Install the shrouds (1&2).
11. Align the spline on the wheel hub to shaft.
12. Then install the steering wheel and install anewbolt. Tighten the bolt to 61 Nꞏm (45 ft. lbs.).
