• Q: How to replace the Drive Shaft in a manual transmission on 2007 Cadillac CTS?

  A: The first step to replace a propeller shaft in a manual transmission car includes lifting the vehicle for support after removing the exhaust system while only disconnecting the bolting between the coupler and transmission flange and detaching the coupler from the shaft. First loosen then delete the propeller shaft coupler-to-differential flange bolts and nuts and washers while maintaining the propeller shaft through support at its support bearing. After removing underbody-support bearing bolts you should push the front propeller shaft backwards to free the transmission flange coupler. The support device should be lowered while keeping hold of the front propeller shaft for removing the support bearing from its mounting studs. When pulling the rear propeller shaft forward you can remove the coupler from the differential flange while notating the shim pack placement for correct assembly then take off the propeller shaft from the vehicle. A detailed evaluation of the propeller shaft coupler should check for split damage, deep cracking and mounting bolt wobble as well as missing or deformed bushings; evidence of such issues requires a new propeller shaft replacement. The installation process requires cleaning the differential flange centering pin along with the transmission flange centering pin as well as front propeller shaft centering bushing and rear propeller shaft centering bushing using a clean shop towel before applying GM P/N 1051344 (Canadian P/N 993037) to these centering bushings. The installation process continues with mounting the rear propeller shaft coupler onto the differential flange while inspecting all propeller shaft-to-flange elements for damage or wear before replacing them. Reposition the support bearing onto the support device while cleaning all threads on recused propeller shaft-to-flange nuts and bolts before applying threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the propeller shaft-to-flange bolt that needs ten minutes for curing. The coupler-to-differential flange nuts require a torque of 85 N.m (63 lb ft) after the install of propeller shaft coupler-to-differential flange washers on propeller shaft coupler and differential flange bolts. After moving the front propeller shaft backward install its coupler to the transmission flange while using the same threadlocker GM P/N 12345493 (Canadian P/N 10953488) cleaning process on the propeller shaft-to-flange bolts with washers. You must attach coupler-to-transmission flange bolts together with washers to coupler and transmission flange, after that install coupler-to-differential flange nuts and tighten them to 85 N.m (63 lb ft). The center support bearing installation requires the vehicle underbody positioning of shim packs in their original locations before the support device raises and enables bearing installation with center support bearing bolt tightening to 50 N.m (37 lb ft). After removal of the support device you should reinstall the exhaust system before lowering the vehicle.
