COMPONENT: Suspension: Front: Wheel Bearing POTENTIAL NUMBER OF UNITS AFFECTED^86333 I SUMMARY: On certain pickup trucks, the front wheel bearing may have received an insufficient quantity of grease during the manufacturing process. CONSEQUENCE: This could result in bearing degradation, and if subsequent noise and vibration are ignored, could result in hub assembly separation. This may result in a loss of vehicle control

4. Align crankshaft sprocket timing mark to the mark on oil pump housing (Fig. 122). NOTE: Lubricate timing chain and guides with engine oil before installation. 5. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links (Fig. 122). 6. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation 1 – CAMSHAFT TIMING MARKS 2 ?

Loosely position left side camshaft sprocket over camshaft hub. 8. Align timing (plated) link tq the crankshaft sprocket timing mark (Fig. 122). 9. Position primary chain onto water pump drive sprocket. 10. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain (Fig. 122) and loosely position over camshaft hub. 11. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets (Fig. 122). 12. Install left side lower chain guide and tensioner arm (Fig. 120). Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary. 13.

Linkage Measurement CAUTION: Before attempting to test the Throttle Position Sensor (TPS), verify the linkage adjustment dimension shown in the figure above. This dimension MUST be 126.5 mm (5.0 inches) BEFORE testing. For linkage adjustment procedures, refer to Throttle Linkage Adjustment. CAUTION: Before testing the TPS, verify that the engine is set at correct low idle speed. Refer to Idle Speed Adjustment. This can be found in the Fuel Delivery and Air Induction system adjustments section. 1. After confirming the correct linkage adjustment and idle speed, proceed to the following: Throttle Position Sensor Location 2. Attach a paper clip into the center terminal of the TPS electrical connector. Do not remove the connector from the TPS for this test. 3. Attach the positive lead of a voltmeter to this paper clip and the negative lead to a good ground. 4. Turn the ignition switch to the ON position. Do not start engine. 5. The voltage at the TPS center terminal should be 1.0 volt (+/- 0.2 volt) with linkage at idle position. The voltage at the wide open throttle position

The heater-A/C housing assembly must be removed from the vehicle and disassembled for service access of the blower motor, blower motor wheel, heater core, evaporator coil, blend-air door, and each of the various mode control doors. WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. REMOVAL 1. Disconnect and isolate the battery negative cable. 2. Remove the instrument panel from the vehicle. Refer to: Body and Frame, Interior Trim, Dashboard/Instrument Panel, Service and Repair, Instrument Panel Assembly Replacement, See: Body and Frame/Interior Moulding / Trim/Dashboard / Instrument Panel/Service and Repair/Instrument Panel Assembly Replacement 3. Recover the refrigerant from the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Refrigerant Recovery, See: Service and Repair/Refrigerant Recovery 4. Remove the front expansion valve from the evaporator tube mounting flange. Install plugs in, or tape over all of the opened refrigerant line fittings. Refer to: Heating and Air Conditioning, Expansion valve, Service and Repair, Expansion Valve Removal and Installation, See: Expansion Valve/Service and Repair 5. Drain the engine cooling system. 6. Disconnect the heater hoses from the heater core tubes.
