• Q: How to replace the steering knuckle on a 4WD on 2006 Chevrolet Trailblazer?

  A: Curent replacement for a 4wd vehicle Steering Knuckle begins with tire center cap removal followed by drive axle nut removal. Start with a vehicle lift to support it at height before removing tire and wheel from beneath. You must first remove the Wheel Hub and bearing before you should take off the outer tie rod retaining nut. The j24319-b steering linkage and tie rod puller allows you to disconnect the outer tie rod from the Steering Knuckle assembly. The brake hose bracket retaining bolts require removal to separate the brake hose bracket from the Steering Knuckle. Unbolt the upper Control Arm from the Steering Knuckle and detach it from the pinch bolt and nut while disconnecting it from the Steering Knuckle. Crystalware Ball Joint remover tool (J43631) helps separate the Steering Knuckle from the lower Control Arm by removing the lower Ball Joint retaining nut. Take off the Steering Knuckle after the vehicle service is complete. Begin installation by mounting the Steering Knuckle onto the lower Control Arm then fasten it with the lower Ball Joint retaining nut and torque the connection to 110 nm (81 ft. Lbs.). Secure the upper Control Arm to the Steering Knuckle through its pinch bolt and nut before tightening them both to 40 nm (30 ft. Lbs.). Screw the brake hose bracket onto the Steering Knuckle while tightening its retaining bolts to 10 nm torques (89 inch lbs.). Use a new outer tie rod retaining nut when installing the rod to the Steering Knuckle before you tighten it to 60 nm (44 ft. Lbs.). The hub assembly and bearing receive new installation followed by tire assembly installation. Lower the vehicle while you install the drive axle nut and tighten it to 140 nm (103 ft. Lbs.) before finishing with a front toe adjustment.
