  Q: How to replace the steering knuckle on GMC Safari?

  A:

  In order to change the Steering Knuckle, start first with an elevating and holding the vehicle, keeping the floor jack under the lower Control Arm to secure its position and avoid personal danger. Take away the tire and wheel, take out the Torsion Bar, as well as the Wheel Hub and bearing. After that, take off the outer tie rod cotter pin and the retaining nut, remove the outer tie rod from the Steering Knuckle, using the steering linkage and tie rod puller (J 24319-B). Have a go to remove upper Ball Joint cotter pin and retaining nut, as well as attach the Ball Joint separator (J 36607) to separate the upper Ball Joint from the Steering Knuckle. Do so again for the lower Ball Joint by first taking off its cotter pin and retaining nut, and using a pry bar to help release the lower Ball Joint stud from the Steering Knuckle. Once having removed the Steering Knuckle from the support and slipped out its seal, install the new seal with the help of the Steering Knuckle seal installer (J 36605). Reinstall the Steering Knuckle to the upper and lower Ball Joint, securing the lower Ball Joint and its retaining nut to 128 nm (95 ft. Lbs.) and the upper Ball Joint to 98 nm (72 ft. Lbs.). Appropriate cotter pins should be installed, nuts should be well tightened to allow for the insertion of the pins, and the ends beaten flat against the nuts. Install the outer tie rod ball stud to the Steering Knuckle and use the retaining nut by tightening up with 49 nm (36 ft. Lbs.), followed by fitting a new cotter pin. Lastly, reinstall the hub and the bearing assembly, load the Torsion Bar, put the tire and wheel in place, lower the vehicle, and inspect the front wheel alignment.

  Q: What tools are required to service and repair the steering knuckle on GMC Safari?

  A:

  The necessary tools for Steering Knuckle maintenance and repair include steering linkage and tie rod puller (J 24319-B) together with Ball Joint separator (J 36607) and Steering Knuckle seal installer (J 36605). Service and repair of the Steering Knuckle requires three key tools: steering linkage and tie rod puller (J 24319-B), ball joint separator (J 36607), and Steering Knuckle seal installer (J 36605). Start the process by lifting the vehicle then positioning it on stands while keeping the floor jack under the lower control arm fixed in position. The service begins by removing the tire and wheel before extracting the Torsion Bar then separating Wheel Hub and bearing. Using the steering linkage and tie rod puller (J 24319-B) remove the outer tie rod from the Steering Knuckle after removing both the retaining nut and the outer tie rod cotter pin. Start by removing the upper Ball Joint retaining nut and cotter pin before attaching a Ball Joint separator tool (J 36607) for upper Ball Joint separation from the knuckle. You should use a pry bar to help release the Steering Knuckle studs before repeating the process for the lower Ball Joint. Insert the seal into the Steering Knuckle through the use of the Steering Knuckle seal installer tool (J 36605). Secure the Steering Knuckle to its ball joints at the connecting points through the upper and lower retaining nuts while torquing the lower Ball Joint retaining nut to 128 nm (95 ft. Lbs.) and the upper Ball Joint retaining nut to 98 nm (72 ft. Lbs.). Use new cotter pins after you tighten the nuts sufficiently to let the pins slip inside. Secure the outer tie rod ball stud with its retaining nut by tightening it to 49 nm (36 ft. Lbs.). Then install a new cotter pin. Reinstall the hub and bearing assembly before loading the Torsion Bar and putting the tire and wheel on followed by lowering the vehicle and checking front wheel alignment.
