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

  A: The first step in Steering Knuckle replacement includes tire removal followed by wheel center cap removal and then drive axle nut removal. The vehicle needs support while you elevate it before moving to remove tire and wheel installations, Wheel Hub units, and bearing assemblies. With the steering linkage and tie rod puller (J24319-B) disconnect the outer tie rod from its mounting on the Steering Knuckle after unscrewing its retaining nut. The brake hose bracket retaining bolts must be removed to free the brake hose bracket from the Steering Knuckle. Begin by unscrewing the pinch bolt at the Steering Knuckle attachment point of the upper Control Arm followed by detachment of the upper Control Arm from the knuckle portion. Extraction of the Steering Knuckle from the lower Control Arm requires removing its lower Ball Joint retaining nut and employing the Ball Joint remover (J43631). The last step is to take out the Steering Knuckle from your vehicle. Installation begins by fitting the Steering Knuckle onto the lower Control Arm but you must always adhere to the fastener notice in service precautions. Fasten the lower Ball Joint retaining nut to 110 nm (81 ft. Lbs. Torque setting). The upper Control Arm should be joined to the Steering Knuckle with the addition of an upper Control Arm pinch bolt and nut before tightening this joint to 40 nm (30 ft. Lbs.). The brake hose bracket mounts onto the Steering Knuckle before securing it with retaining bolts tightened to 10 nm (7 ft. Lbs.). After installing the outer tie rod to the Steering Knuckle, fasten a new outer tie rod retaining nut and set its torque to 45 nm (33 ft. Lbs.). The Wheel Hub and bearing assembly goes back onto the vehicle along with the tire and wheel assembly before the vehicle is lowered and the drive axle nut is installed and tightened to 140 nm (103 ft. Lbs.). After installing the drive axle nut tighten it to 140 nm (103 ft. Lbs.) while performing front toe adjustments.
