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.

The J 38792-A  can be used to identify the light spot on a propeller shaft IF the propeller shaft rotational speed is the dominant frequency of the vibration concern. See Special Tools . The J 38792-A  is equipped with a strobe light trigger wire which can be used with an inductive pickup timing light, J 38792-25  , or equivalent included with the J 38792-KIT, or available separately, and in conjunction with the J 38792-A  vibration sensor to identify the light spot on a propeller shaft and to help in making a determination as to when propeller shaft balance is obtained.
