• Q: How to replace the rear Drive Shaft on 2003 GMC Safari?

  A: The first step in rear propeller shaft replacement requires that you elevate the vehicle while marking the precise alignment of driveline components between the propeller shafts and drive axles and pinion flanges and output shafts to preserve factory system dynamic equilibrium. Take care when removing the bolts at the rear end of the pinion flange as well as the retainers by avoiding forceful impact on original propeller shaft yoke ears which could damage the injection joints. Put the yoke and cross assembly aside while taping both bearing cups to retain the rollers inside before pushing the propeller shaft forward toward the rear axle below its position without bending the Universal Joint too steeply. The cleaning process should use appropriate solvent on all components while inspecting nylon yoke burrs at the outer diameter to achieve proper bearing cup placement as well as examining spline wear and twisting on the Slip Yoke. New universal joints need installation whenever the slip joint or companion flange requires service while the slip joint requires lubrication before installing the yoke and cross assembly onto the pinion flange and setting the reference marks on the pinion flange and the propeller shaft rear yoke correctly before proper yoke seating. Secure the retainers along with the bolts into the pinion flange while torquing them to 36 nm (27 ft. Lbs.) then lower the vehicle.
