Subject:
Knocking Type Noise Coming From Front of Vehicle When Accelerating and Turning (Regrease Both Left and Right Front Wheel Drive Shaft Outer
Joints)
Models:
2008 Saturn VUE
with V6 Engine (VINs 7, N - RPOs LY7, LZ4)
Condition
Some customers may comment on a knocking type noise coming from the front of the vehicle when accelerating and turning. This noise will typically
only occur after a cold soak in temperatures below freezing and will go away after a few moments of driving or after the vehicle warms up. This
condition is only present when both accelerating and turning.
Cause
The cause of this condition may be due to the grease solidifying in the front axle shaft outer joint in cold temperatures.
Correction
Regrease both the left and right front wheel drive shaft outer joints following the procedure listed below. Use the synthetic grease provided in the new
boot kit P/N 19178957.
1.
Remove both the left and right front wheel drive shafts from the vehicle following published procedures in SI.
2.
Clamp the drive axle shaft in a soft jawed vice.
