• Q: How to replace the front drive shaft on 2007 Cadillac STS?

  A: The first step for front propeller shaft replacement is raising your vehicle and supporting it before removing the propeller shaft heat shield. Locate and make a mark for the constant velocity (CV) joint of the propeller shaft that attaches to the transfer case flange. The next step involves removing the propeller shaft CV Joint-to-differential flange bolts before placing a flat-bladed tool into the differential flange notch. Move the propeller shaft systematically backward towards the vehicle rear to detach its CV Joint from the differential pinion flange before removing the CV Joint-to-transfer case flange bolts. Use a flat-bladed tool to put into the transfer case flange notch then shift the propeller shaft forward for detachment from the transfer case flange. Check for rotational freedom between the CV Joint and propeller shaft tube and examine the cv joints for damage as well as seals and grease leaks and both joint bindings; any detection requires you to replace the front propeller shaft. The first step for installation requires positioning the tapered end of the CV Joint into the transfer case flange while you attach the propeller shaft to both transfer case and differential flanges. The propeller shaft-to-flange bolts must be replaced when damaged but should be cleaned first before using threadlocker gm p/n 12345493 (Canadian P/N 10953488) which requires 10 minutes to cure. The CV Joint-to-differential flange bolts require crescent washers for installation with a bolt torquing sequence of 1-6 to 40 n.m (29 lb ft). This procedure must also be done for CV Joint-to-transfer case flange bolts. Examine for any rotation between the CV Joint and propeller shaft tube before reinstalling the propeller shaft heat shield and returning the vehicle to its normal position.
