Models Affected:
2002-2004 Saturn VUE vehicles with All Wheel Drive (RPO GQ1)
Condition:
Some customers may comment on a drone noise between 50 to 75 mph (80 - 120 km/h). This noise may be accompanied with a slight vehicle vibration
mostly noticeable during light to moderate acceleration.

Replacement" procedure in the appropriate Saturn VUE Service Manual).
Service Procedure:
1.
Verify the customer concern. If using the Electronic Vibration Analyzer, J38792A, or similar tool, look for a 30Hz vibration that exceeds 0.1 g's at
70 mph (113km/h).
Important:
The notches in the bushing assembly must be oriented at the 12 and 6 o'clock positions.
2.
Replace rear mount bushing assembly on the RDM with P/N 22715607 by following the appropriate Service Manual procedures. (Refer to
"Differential Carrier Assembly Mount Replacement" procedure in the appropriate Saturn VUE Service Manual).
