Sierra 1500 2WD V8-5.3L VIN B HO (2006)
To determine the source of the customer's concern, use chassis-ears to evaluate the body mount area and the frame torsion bar cross-member. An I-shaft
concern can be felt as a "chucking" feel through the steering wheel. After the chassis-ears are installed, drive the vehicle to evaluate the customer's
concern.
If it is determined that the cause of the customer's concern is due to the body mount or torsion bar crossmember, proceed with the appropriate repair. If it
is determined that the cause of the concern is the I-Shaft, follow the repair procedures/bulletins found in published Service Information (SI) concerning
I-shaft lubing/replacement.
