2003 GMC Truck C 1500 P/U 2WD Engine Knocking or Lifter Noise

Engine Lubrication: All Technical Service Bulletins Engine – Knocking or Lifter Noise File In Section: 06 – Engine/Propulsion System Bulletin No.: 02-06-01-038 Date: December, 2002 TECHNICAL Subject: Engine Knock or Lifter Noise (Replace 0-Ring) Models: 2001-2002 Chevrolet Camaro 2001-2003 Chevrolet Corvette 2001-2002 Pontiac Firebird 2002-2003 Cadillac Escalade, Escalade EXT 2000-2003 Chevrolet Suburban, Tahoe 2001-2003 Chevrolet Silverado 2002-2003 Chevrolet Avalanche 2000-2003 GMC Yukon, Yukon XL 2001-2003 GMC Sierra with 4.8L, 5.3L, 5.7L or 6.0L V8 Engine (VINs V, T, Z, G, S, N, U – RPOs LR4, LM7, L59, LS1, LS6, LQ9, LQ4) Condition Some customers may comment on an engine tick noise. The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter . Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi). Cause The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil. Correction

If at this point the vehicle does not run rough and/or stalls when the active test is performed, proceed with Repair Manual P1349 VVTi Fault Isolation Procedure (FIP). If the vehicle does stall and/or runs rough, this indicates the the VVTi control system is operating. Proceed to replace the VVTi actuator following the repair procedures listed on the Technical Information System (TIS): Engine Mechanical Section, Camshaft, Replacement The camshaft timing gear should come in the unlocked position from the factory. If it is difficult to install the camshaft timing gear, the lock pin may be engaged. To disengage the lock pin, apply and hold approximately 20 psi of air pressure at the oil feed hole located 90 degrees clockwise of the oval slot. (See Figure 1.) Once the pin has released, turn the interior assembly counterclockwise. (See black arrow in Figure 1.) B. Put the camshaft timing gear assembly and the camshaft together with the straight pin off the key groove. C. Turn the camshaft timing gear assembly (as shown in Figure 2) while pushing it lightly against the camshaft. Push further at the position where the pin fits into the groove. NOTE: Be sure not to turn the camshaft timing gear to the retard angle side (in the clockwise direction). D. Check that there is no clearance between the end of the camshaft and the camshaft timing gear. E. Tighten the camshaft bolt with the camshaft timing gear fixed. Torque: 54 Nm (551 kgfcm, 40 ftlbf) F. Check that the camshaft timing gear assembly can move to either side and is not locked

1. Remove the differential case. For additional information, refer to Differential Case in this section. 2. NOTE: The differential bearings need not be removed to overhaul the Ford limited slip differential. If bearing removal is required, for additional information, refer to Differential Case in this section. NOTE: The anti-lock speed sensor ring cannot be reused once removed. Remove the differential pinion shaft lock bolt and remove the differential pinion shaft. ? If required, remove the ring gear and anti-lock speed sensor ring. 3. NOTE: This tool does not have the 1/2-inch drive hole. Install the special tool in a suitable vise. 2003 F-Super Duty 250-550/Excursion Workshop Manual 5. Install the special tool in the bottom side gear bore. ? Apply a small amount of grease to the centering hole of the special tool. 6. Install the nut in the upper differential side gear. Hold the nut in position while installing the hex screw. Tighten the hex-head screw until contact is made with the Step Plat 2003 F-Super Duty 250-550/Excursion Workshop Manual 7. Insert a suitable dowel bar in the hole of the nut. Tighten the forcing screw to force the differential side gear away from the differential pinion gears. The dowel bar is used to keep the nut from turning when the forcing screw is tightened. NOTE: Differential pinion thrust washers cannot be removed independently of the differential pinion gears and so must be removed simultaneously with the differential pinion gears. Insert the special tool in the pinion shaft bore and turn the differential case to “walk” the differential pinion gears and differential pinion thrust washers out to the differential case windows. 9. Remove the differential pinion gears and differential pinion thrust washers. 10. Remove the differential side gears and differential clutch packs and tag them RIGHT and LEFT with the shim
