ISSUE
Some 2007-2009 Ranger vehicles equipped with a 2.3L engine and automatic transmission may exhibit an engine drone/moan/vibration at idle in the cab.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. Remove the three (3) rear pushpins and position the right inner fender splash shield aside.

2. Loosen the two (2) right hand (RH) and two (2) left hand (LH) engine support insulator upper nuts to allow 1/4" (6 mm) to 1/2" (12 mm) clearance between nut and mount plate.

3. Install exhaust damper following instructions included in the damper installation kit.

4. Loosen the two (2) exhaust downpipe-to-exhaust manifold nuts. Allow 1/4" (6 mm) to 1/2" (12 mm) clearance of nut surface.

5. Loosen the joint clamp at the muffler inlet pipe.

6. Loosen the two (2) transmission mount bolts and two (2) isolator-to-transmission bolts and allow 1/4" (6 mm) to 1/2" (12 mm) clearance.

7. From passenger side of engine, grab and shake the engine assembly to allow the engine mounts to seek a neutral position.

8. From the driver side of engine, grab and shake the engine assembly to allow the engine mounts to seek a neutral position.

9. Install the two (2) LH and two (2) RH engine support insulator-to-engine support bracket nuts. Tighten to 75 lb-ft (102 N.m).

10. Position the right inner fender splash shield and install the three (3) rear pushpins.

11. Shake the exhaust system until it seeks a neutral position.

12. Tighten the transmission mount and the isolator-to-transmission bolts. Tighten to 66 lb-ft (90 N.m).

13. Tighten the upper exhaust downpipe-to-exhaust manifold nut until partially tight. Tighten the lower manifold nut until completely tight. Complete the tightening process on the upper manifold nut to the specified torque. Tighten both nuts to 30 lb-ft (40 N.m).

14. Tighten the joint clamp at the muffler inlet pipe. Tighten to 30 lb-ft (40 N.m).

5. Start the engine and check the exhaust system for leaks.

16. Reprogram the Powertrain Control Module (PCM) to the latest calibration using Integrated Diagnostic System (IDS) release 64.06 and higher.
