NOISE - "MOANING/DRONING" DURING LIGHT
ACCELERATION AT HIGHWAY SPEEDS

LINCOLN:
2000 LS

ISSUE
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. The larger diameter halfshafts should reduce the resonant frequencies generated by the powertrain. Refer to the 2000 LS Workshop Manual, Section 205-05 for installation procedure.
