Propshaft Noise Some owners of a 2002-05 Chevrolet TrailBlazer EXT 2WD, or GMC Envoy XL 2WD, or 2003-05 Chevrolet SSR may comment on a ping, pop or click noise from underneath the rear of the vehicle. This concern usually occurs when shifting into Reverse, or out of Reverse into Drive.
On TrailBlazers and Envoys equipped with a 3.42 axle ratio (RPO GU6), or a 3.73 axle ratio (RPO GT4), this condition can be corrected by replacing the original swaged aluminum propshaft with a straight tube propshaft from the GMC Envoy XUV.
- p/n 15113111 for vehicles equipped with the 4.2L L6 (RPO LL8)
- p/n 15113110 for vehicles equipped with the 5.3L V8 (RPO LM4).
The propshafts mentioned above CANNOT be used in TrailBlazers and Envoys with the 4.10 axle ratio (RPO GT5). If this concern appears on a vehicle with the 4.10 ratio, use p/n 15163667, which is the same as the original propshaft.
On Chevrolet SSRs, a revised propshaft for automatic transmission vehicles p/n 15247556 was released for service, which includes an integral mass damper, mounted on the slip-yoke (transmission end) to improve a driveline whine concern. Manual transmission (6-speed) vehicles use p/n 15209860 which has a larger rear u-joint to fit the 9.5-inch rear axle. These propshafts have also been changed internally to reduce the ping, creak or click noise when the direction of the propshaft is reversed.
