INTAKE MANIFOLD | REMOVAL AND INSTALLATION
(Refer to illustration 3.2)

REMOVAL

1. Disconnect the cables from the negative and positive terminals of the battery and then remove the battery and battery box (see Chapter 5).



2. Remove the air intake hose from the air cleaner resonator box over the valve cover, then pry up the resonator box from the clips at the right side of the valve cover (see illustration).



3. Remove the throttle body (see Chapter 4).



4. Disconnect the electrical harnesses from their brackets and the MAP sensor connector.



5. Remove MAP sensor bracket.



6. Disconnect the crankcase vent hose from its ports on the manifold and valve cover.



7. Remove the engine harness bracket. To access the lower engine harness, support the vehicle on jackstands and remove the left front wheel and inner fender liner (see Chapter 11).



8. Remove the alternator (see Chapter 5).



9. Disconnect the vacuum hose from the power brake booster. On 2007 and later models, remove the oil dipstick and dipstick tube.



10. Loosen the left front wheel lug nuts, then raise the front of the vehicle and support it securely on jackstands. Remove the left front wheel and refer to Chapter 11 and remove the plastic inner fender liner.



11. Working through the fender well opening, remove the lower wiring harness bracket, then the intake manifold bolts and remove the manifold.



12. Remove the old gasket, and then clean and inspect the intake manifold for damage, cracks and warping.

DRIVESHAFT(S) | REMOVAL AND INSTALLATION

REAR DRIVESHAFT
(Refer to illustrations 10.2 and 10.3)

REMOVAL

1. Raise the vehicle and support it securely on jackstands. Place the transmission in Neutral with the parking brake off. Block the front wheels to prevent the vehicle from rolling.



2. Make reference marks on the driveshaft and the pinion flange in line with each other (see illustration). This is to make sure the driveshaft is reinstalled in the same position to preserve the balance.



3. Remove the rear universal joint bolts and straps. Turn the driveshaft (or wheels) as necessary to bring the bolts into the most accessible position. To prevent the driveshaft from turning when you loosen the bolts, insert a large screwdriver through the driveshaft yoke (see illustration).



4. Tape the bearing caps to the spikder to prevent the caps from coming off during removal. On models with center support bearing, remove the support bearing mounting bolts (see illustration 9.2).



5. Lower the rear of the driveshaft. Slide the front of the driveshaft out of the transmission or transfer case.



6. Wrap a plastic bag over the transmission or transfer case housing and hold it in place with a rubber band. This will prevent loss of fluid and protect against contamination while the driveshaft is out.
