ISSUE Various 1997-2008 vehicles equipped with either 4 wheel drive or all wheel drive and equipped with control trac may exhibit a shudder on acceleration/deceleration, binding in slow speed turns or noise from the front driveline and/or transfer case. The shudder/binding will occur with the vehicle being operated in the awd/auto 4×4 mode. The shudder/binding may be due to incorrect tire circumference or improper tire inflation pressures. ACTION Follow the Service Procedure steps to correct the 1. Review the tire label for correct tire size and tire inflation pressures located at the B-Pillar of the driver’s door. 2. If the tire size does not match the label, this procedure does not apply, follow normal Workshop Manual (WSM) diagnostics. 3. If the tire size is correct, ensure tire pressures are within specifications. 4. Raise the vehicle on the hoist, refer to Workshop Manual, Section 100-02. 5. Disconnect all wiring going to the transfer case and road test. 6. Is the shudder/binding present? a. If the shudder/binding is still present, do not contine with this procedure, continue with WSM normal diagnostic for 4X4. b. If the shudder/binding is gone, proceed to Step 7. 7. Raise the vehicle on the hoist and reconnect all the wiring previously disconnected. 8. Using a tailor’s tape or flexible measuring tape and measure the circumference of all four (4) tires and record the measurements. (Figure 1)

ISSUE Some 2007-2008 F-150 and Mark LT vehicles built between 12/4/2006 to 5/20/2008 and equipped with a 5.4L 3V and 4R75E, may exhibit an engine RPM flare during light acceleration during the 3-4 upshift. This would only occur at road speed ranges from 25-30 MPH (40-48 Km/h). No DTCs or other drivability or transmission issues would be present. ACTION Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 54.5 and higher. This new calibration is not included in the VCM 2008.3 DVD. Calibration files may also be obtained at www.motorcraft.com.

Here is one idea that will let you utilize the Surbo system to the maximum. Attaching a boost gauge, you will be able to get the most power per throttle travel (->press less, get more power). It’s not for measuring a boost output, but as a means of consistently commanding the Surbo, especially under low-torque situations at very low rpm and/or in a very high gear. If you do not wish to install a gauge, just reading this page will help you understand the Surbo system better. Note: “gauge” and “meter” refer to the same thing. Please also refer to How The Surbo System Works to see how the boost gauge (white circle) is positioned within and related to the Surbo system. Why A Boost Gauge? When you have your gauge installed and you drive normally, you will realize that it is always pointing up and down. This means that supply of air (from the air intake) is not equal to demand for air (by the engine), especially during acceleration, or after gearchanges, or driving under different loads or terrain, or a combination of the above. When the demand for air is not met by the air intake (indicated by a falling needle on the meter), this can reduce engine power. With the meter attached to and reading from the air manifold (the holding area between the throttle and engine), once you balance the needle at any point by moving your right foot, supply=demand and the airflow will be optimized. By moving your foot, the Surbo is activated automatically! Background The boost gauge had found a new use as a Surbo trigger on our test car. While we wanted our customers to have the same fun, problems resulted as customers could not choose or find suitable gauges or supervise the job as stated; almost always, based on user feedback and our own checks, unknown installers did poor jobs that caused leaks to the vacuum and resulted in Surbo failure as well. So we have to write a clear guide to prevent failure during installation, for you to use in supervising the job. You can’t just leave it to the installers as they won’t care about giving you a perfect seal.

Various 1997-2008 vehicles equipped with either 4 wheel drive or all wheel drive and equipped with control trac may exhibit a shudder on acceleration/deceleration, binding in slow speed turns or noise from the front driveline and/or transfer case. The shudder/binding will occur with the vehicle being operated in the awd/auto 4×4 mode. The shudder/binding may be due to incorrect tire circumference or improper tire inflation pressures. ACTION: Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE NOTE: THIS DOES NOT APPLY TO 2006-2008 MOUNTAINEER WITH A 4.0L ENGINE OR 2007-2008 EXPLORER AND SPORT TRAC WITH 20 INCH WHEELS. Review the tire label for correct tire size and tire inflation pressures located at the B-Pillar of the driver’s door. If the tire size does not match the label, this procedure does not apply, follow normal Workshop Manual (WSM) diagnostics. If the tire size is correct, ensure tire pressures are within specifications. Raise the vehicle on the hoist, refer to Workshop Manual, Section 100-02. Disconnect all wiring going to the transfer case and road test. Is the shudder/binding present? a. If the shudder/binding is still present, do not contine with this procedure, continue with WSM normal diagnostic for 4X4. b. If the shudder/binding is gone, proceed to Step 7. 7. Raise the vehicle on the hoist and reconnect all the wiring previously disconnected. 8. Using a tailor’s tape or flexible measuring tape and measure the circumference of all four (4) tires and record the measurements. (Figure 1) 1. 2. 3. 4. 5. 6. 10. If the difference between these two averages is greater than 1/2″ (12.7 mm), front to back or side to side, replace the smallest circumference tire(s) and remeasure the tire averages. Refer to WSM, Section 204-04 for tire replacement.

Nissan is conducting a voluntary safety recall on model year 2003 – 2007 Murano vehicles. Under certain conditions, the intake duct, which is connected to the intermediate resonator in the air intake system of the engine, may separate from the resonator with engine movement. This could cause minor idle fluctuation or poor acceleration. If this occurs, and the vehicle continues to be driven without being serviced, the engine may stall while driving. To remedy this potential condition, Nissan is conducting this voluntary safety recall campaign to replace the air intake duct with an updated part and the air duct clamps with new clamps at no charge for parts or labor. SERVICE PROCEDURE CAUTION: Do not use any lubricant when removing or installing the air ducts and resonators. Lubricant may adversely affect the ducts and resonators. 1. Disconnect the Positive Crankcase Ventilation (PCV) hose from resonator 1. 2. Loosen the clamps shown in Figure 1 (clamps at both ends of the air duct assembly). 3. Remove the air duct assembly from the vehicle and set it on a clean working surface. 4. After removing the air duct assembly, cover the openings to the electronic control throttle and airflow meter with clean cloth / rags. CAUTION: • Make sure to cover the openings to the electronic control throttle and airflow meter. • Covering the openings will prevent debris entry. 5. Loosen both wire clamps shown in Figure 2 (clamps on both sides of resonator 1). 6. Replace the wire clamp on air duct B. a. Pull air duct B away from resonator 1 just enough to remove the old wire clamp and install a new one. • Bend the old wire clamp so it cannot be reused. b. Reconnect air duct B to resonator 1. CAUTION: Before installing air duct B, use a clean cloth / rag to wipe away any debris from the duct and resonator.
