| NOISE – “MOANING/DRONING” DURING LIGHT ACCELERATION AT HIGHWAY SPEEDS |
| LINCOLN: | 2000-2002 LS |
Some vehicles may exhibit a “moaning/droning” noise during light accelerations with the transmission in 5th gear at highway speeds (100-130 km/h (60-65 mph) for V6 vehicles or 80-90 km/h (50-55 mph) for V8 vehicles).
This noise will disappear if the transmission is shifted to 4th gear or when lifting the throttle.
The noise may be due to the body reacting to a resonant frequency generated by the powertrain.
ACTION:
Install revised larger diameter rear halfshafts (1W6Z-4K138-AA (RH) and 1W6Z-4K139-AA (LH).
The larger diameter halfshafts should reduce the resonant frequencies generated by the powertrain.
