WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Before disassembly, observe and accurately reference mark all driveline components relative to the propeller shaft and axles. These items include the following components:
  • The propeller shafts
  • The wheel drive shafts
  • The pinion flanges
  • The output shafts

Assemble all components in the exact relationship to each other as they were prior to removal. Observe all published specifications and torque values, and any measurements obtained prior to disassembly.

    NOTE: When removing the propeller shaft, do not attempt to remove the shaft by pounding on the yoke ears or using a tool between the yoke and the universal joint. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint.
  5. Remove the bolts (6) and the yoke retainers (7) from the front axle pinion yoke (1).
    6. IMPORTANT: Do not drop the bearing cap assemblies of the yoke end.
  6. Disconnect the propeller shaft (2) from the front axle pinion yoke (1).
