Constant velocity joint boot service and repair; specifically the wheel drive shaft outer joint and seal replacement requires: snap ring pliers (J 8059), seal clamp tool (J 35910), drive axle clamp swage tool (J 36652-1), and drive axle clamp swage tool (J 36652-2). These tools are essential for bnsf railway mechanics, as they will be used to change the snap rings, seals, and drives of the vehicles, ultimately maintaining maximum efficiency of the vehicles. Start by using a hand grinder, cutting through the swage ring, and removing the small boot clamp with the use side cutters. Slide the boot down the half shaft bar and clean the CV Joint. Open the snap ring ears with the snap ring pliers (J 8059), and take out the CV Joint and the boot from the halfshaft bar, discard the old boot. Remove the chrome alloy balls from the cv joints cage also and ensure that all components are clean. Check for wear or damages and replace parts as needed. Put grease into the inner and outer race grooves, align and install the inner race in the cage to install it into the outer race. Install chrome alloy balls; pack the CV Joint boot and assembly with grease; and in order now attach the small boot clamp with seal clamp tool (J 35910) to the given torque. Make sure the CV Joint inner race retaining ring side is turned to the halfshaft bar before mounting the CV Joint over it. Finally, use the drive axle clamp swage tool (J 36652-1 or J 36652-2) to clamp the CV Joint boot on to the outer race so that it is aligned properly and clamp the CV Joint assembly in place with the bolts provided.
