  Q: How to replace the rear Drive Shaft on Cadillac Escalade EXT?

  A:

  The first step to change the rear propeller shaft requires accurate markings of driveline elements relative to the shafts and axles prior to disassembly which includes both propeller shafts and drive axles and pinion flanges and output shafts requiring exact reassembly positioning as original. You should raise the vehicle to note the propeller shaft position regarding the front yoke of the rear axle and both the transmission and Transfer Case. Use a socket and wrench to remove the boltages as well as yoke retainers attached to the rear axle pinion yoke . Refrain from using tools along the yoke and Universal Joint interface and prevent striking the ears of the yoke while removing it. To remove the propeller shaft from the vehicle start by sliding the rear axle pinion yoke forward after disconnecting it from the transmission or Transfer Case motion. The Slip Yoke splines require inspection for proper lubrication after which you should apply gm p/n 12345879 (Canadian P/N 10953511) or equivalent lubrication matching gm specification 9985830 (RWD w/4 speed Automatic Transmission). To install the propeller shaft in the transmission or Transfer Case identify reference marks from removal resulting in proper shaft alignment with the rear axle pinion yoke where appropriate reference marks should be situated. First install the retainers and bolts and then secure the yoke retainer bolts until they achieve a torque of 25 n.m (18 lb ft). Finally, lower the vehicle.

  Q: How to replace the front drive shaft on Cadillac Escalade EXT?

  A:

  The first step to replace a front propeller shaft includes lifting the vehicle while taking off the Transfer Case shield if present. The narrow jaw clamp of j 43218 clamp pliers - narrow jaw (J 43218) should be used to prise up the exposed end of the Transfer Case clamp. Notate where the propeller shaft fits with the front axle pinion yoke before you take off its retaining bolts and yoke mounters from the front axle pinion yoke. The propeller shaft removal should occur from the front axle pinion yoke with bearing caps tied by tape to avoid roller loss. To detach the propeller shaft move it forward while extracting it from the groove on the Transfer Case output shaft. Check the splines on the Transfer Case output shaft for proper lubrication then use gm p/n 12345879 when applying lubrication (Canadian P/N 10953511) or equivalent products. Reposition the propeller shaft boot before installing its clamp and slide the propeller shaft splines through the Transfer Case output shaft. The propeller shaft should be attached to the front axle pinion yoke with proper reference mark alignment from removal. Securing it requires the yoke retainers and bolts tightened to 25 n.m (18 lb ft). Finish the operation by placing boot onto the Transfer Case output shaft and use j 43218 clamp pliers - narrow jaw (J 43218) to crimp both clamps before installing the Transfer Case shield and lowering the vehicle.
