GM 15919080
Axle Assembly, Rear Driver Side

The replacement of the front left wheel drive shaft begins with vehicle lift and support followed by removal of the left front wheel and tire. Disconnect the left Steering Knuckle Tie Rod End from the Steering Knuckle yet keep the Tie Rod End jam nut tight. The brake rotor requires a drift or punch that should go through it and rest against the brake caliper mounting bracket to stop Wheel Hub and bearing motion. New replacement nuts must be used for replacing the wheel drive shaft Spindle Nut because previous usage invalidates it. The Wheel Speed Sensor electrical connector should be detached from the sensor before moving the wiring harness away from the Ball Joint position. The Ball Joint on the left side upper section should be detached from its connection to the Steering Knuckle. Fix the Wheel Hub remover (J 45859) onto the Wheel Hub but secure it with wheel nuts only after you support the wheel drive shaft until it is fully removed. Disengage the left front wheel drive shaft from the Wheel Hub and bearing through use of the Wheel Hub remover j 45859 until successful removal from the vehicle. The technicians must use slide hammer with adapter (J 2619-O1) combined with extension (J 29794) and Axle Shaft puller (J 45341). They should place the puller (J 45341) into the inner joint pull groove area of the wheel drive shaft. The assembled tools should be used to disengage the wheel drive shaft from the intermediate wheel drive shaft. When keeping the intermediate wheel drive shaft remove the wheel drive shaft retaining ring along with the o-ring from their designated grooves. Attach a new o-ring and wheel drive shaft retaining ring to the intermediate wheel drive shaft following gm p/n 01051344 (Canadian P/N 993037) grease application to the splines. The left front wheel drive shaft will install to the intermediate wheel drive shaft while extracting outward force on the inner joint housing to achieve proper coupling. First install both the left wheel drive shaft to its hub and bearing followed by its Ball Joint installation on the Steering Knuckle before connecting the speed sensor electrical cable. The new wheel drive shaft Spindle Nut should be loosely threaded then a drift or punch should be placed into the rotor against the caliper mounting bracket until the Spindle Nut reaches 160 nm (118 ft. Lbs. Of torque). Before vehicle lowering complete the procedure by connecting the outer Tie Rod End to the Steering Knuckle followed by wheel and tire assembly installation.

Remove the drift or punch from the rotor, connect the outer tie rod end to the steering knuckle, install the tire and wheel assembly, and lower the vehicle.

A suitable tool to carefully release the wheel drive shaft.
