PURPOSE
This document provides instructions on how to resolve an in-cabin fuel smell detected while
the vehicle is idling or being driven, and should be performed on a customer complaint basis.

BACKGROUND
Fuel evaporation may cause a fuel smell to be present inside the vehicle cabin while the vehicle is
idling or being driven. This is a result of the canister vent positioned on a side-member that is
connected to the vehicle cabin. The concern is resolved by changing the structure of the vent pipe
and positioning it to the rear wheel house.

BACKLASH OF CENTER BEARING

Move the shaft near center bearing up and down and from side to side (axial direction of shaft and right angle to shaft) to check that the bearing has no backlash. If the bearing has a malfunction,
remove propeller shaft and perform inspection.

CF100ABEAA00USA

APPEARANCE AND NOISE
•

Check the propeller shaft tube surface for dents or cracks. If malfunction is detected, replace propeller shaft assembly.

•

If center bearing is noisy or damaged, replace propeller shaft assembly.

VIBRATION
If vibration is present at high speed, adjust the propeller shaft phase first.
1.Check the propeller shaft for bend and damage. If damaged, replace propeller shaft assembly.
2.Perform a cruise test drive to check the propeller shaft for runout. If vibration occurs, separate propeller shaft at final drive companion flange; then change the phase between companion flange and
propeller shaft by the one bolt hole at a time and install propeller shaft.
3.If vibration is still detected, measure propeller shaft runout after removing it. Refer to Inspection.
