ISSUE: Gear noise, commonly referred to as "gear rattle", may enter the cab through the manual transmission shift lever floor pan opening. This noise is normally noticed when the vehicle is at normal operating temperatures and a load is applied to the engine between 500 and 1000 RPM.
ACTION: Inspect and evaluate the vehicle for gear rattle. If gear rattle is detected, install a new shift boot over the shift lever to limit gear noise from entering the cab. Refer to the following procedure for service details.
INSPECTION PROCEDURE:
1. Drive the vehicle till normal operating temperatures are maintained (about 10 miles at highway speeds when the ambient temperatures are above freezing.)
2. On a smooth road surface, place the shift lever in 2nd or 3rd gear and accelerate starting at 500 RPM.
3. If gear rattle is heard and is diagnosed as coming through the shift lever floor pan opening, repair using the following procedure.
REPAIR PROCEDURE:
1. Remove the shift knob from the shift lever.
NOTE: TO REMOVE THE SHIFT KNOB WITHOUT DAMAGE, PLACE A 16 mm OR AN ADJUSTABLE OPEN END WRENCH UNDER THE SHIFT KNOB END AND STRIKE THE WRENCH UPWARD WITH A HEAVY HAMMER.
2. Remove the (4) screws which secure the boot to the floor. Remove the boot assembly from the the shift lever.
3. Install the new boot assembly over the shift lever and secure to the floor with the the (4) screws provided.
NOTE: USE A SOAP SOLUTION TO ASSIST IN INSTALLING THE SHIFT BOOT OVER THE SHIFT LEVER.
CAUTION: DO NOT USE A HYDROCARBON (OIL) OR GLYCOL BASED LUBRICANT TO AID IN INSTALLING THE SHIFT BOOT. THESE MATERIALS WILL GET INTO THE SHIFT LEVER SPLINES AT THE SHIFT KNOB END OF THE LEVER AND CAUSE THE SHIFT KNOB PLASTIC CORE TO CRACK.
4. Install the shift knob on the shift lever.
