Knuckle, Driver Side

The replacement of a 2500 series Steering Knuckle requires these specific tools: ball joint remover (J 43631), ball joint separator protector adaptor (J 45851) and Ball Joint separator (J-42188-B). The tool kit for Steering Knuckle replacement includes Ball Joint remover (J 43631), ball joint separator protector adaptor (J 45851), and Ball Joint separator (J-42188-B). First raise and support the vehicle and then take off the wheel together with the tire. First stabilize the lower Control Arm before you extract the Wheel Hub paired with the bearing assembly. Prior to installation disconnect the outer tie rod from the Steering Knuckle while you also disassemble the brake hose bracket retaining bolt. The Ball Joint separator (J-42188-B) enables Ball Joint separation from the Steering Knuckle after you remove the upper Control Arm retaining nut. Use the Ball Joint remover (J 43631) with the Ball Joint separator protector adaptor (J 45851) to remove the lower Ball Joint from the Steering Knuckle following lower Control Arm retaining nut removal. Before fitting new components clean all grease residue and contaminants from the tapered edges and threading surfaces of upper ball joints, lower ball joints and tie rods. Steering knuckles should get replacement when inspection shows elongated or out-of-round or damaged holes found in the mounting surface or taper areas. First install the new Steering Knuckle before attaching the lower Ball Joint and installing the retaining nut which must be tightened to 110 n.m (81 lb ft). Tighten the upper Ball Joint's retaining nut to 50 n.m (37 lb ft). Attach the brake hose and bracket retaining bolt before tightening it to 9 n.m (80 lb in). Next secure the outer tie rod to the Steering Knuckle. After placing the Wheel Hub and bearing assembly install the tire and wheel. Inspect wheel alignment after lowering the vehicle and removing its lower Control Arm support.

A driver must elevate their vehicle for maintenance before removing the wheel and tire to replace a Steering Knuckle in a 1500. The wheel drive shaft must be taken out of the vehicle when it is present in models 1500. Follow the procedure to eliminate the Wheel Bearing and hub assembly (2500). First disconnect the outer tie rod from the knuckle before unfastening the upper Control Arm together with the lower Control Arm from the knuckle. When servicing the lower Ball Joint exclude disconnecting the brake hose as well as all electrical components but keep the knuckle assembly secured to the side during knuckle removal from the vehicle. Ball joints must be installed at their proper positions beginning with the lower joint into the knuckle then the upper one. You should install the outer tie rod onto the knuckle before putting on the Wheel Bearing with hub assembly for 2500 models. Proceed with wheel drive shaft installation (1500) after which add the tire along with the wheel. Complete the installation by taking away the support system and dropping the vehicle before conducting a wheel alignment test.

Begin Steering Knuckle replacement by lifting the vehicle to support it then proceed with tire and wheel removal. Start by removing the wheel drive shaft when equipment includes it followed by the Wheel Bearing and hub assembly. Following the removal of the outer Tie Rod End from the knuckle, personnel must detach the upper Control Arm and lower Control Arm from the knuckle before they can remove the knuckle. Lower Ball Joint mounts into the knuckle first and upper Ball Joint goes in next for assembly. Begin by reattaching the outer Tie Rod End; after that install the Wheel Bearing and hub assembly and the wheel drive shaft if present. Reinstall the tire and wheel followed by support removal and lowering the vehicle until you check the wheel alignment.

To change the Steering Knuckle (2500), start with the removal of the tire and wheel and wheel drive shaft in case of equipment. The next step is to remove the Wheel Bearing and hub assembly, and remove the outer Tie Rod End from the knuckle. Unsupport the lower Control Arm and free the upper Ball Joint from knuckle then the lower Ball Joint. Lastly, take the knuckle off the vehicle. For the installation, slip in the knuckle onto the lower Ball Joint and at last install the upper Ball Joint into the knuckle. The outer Tie Rod End and the Wheel Bearing and hub assembly must be reattached. In case it's equipped, install the wheel drive shaft after which now remove the support from the lower Control Arm. Replace the tire and wheel and check the wheel alignment accordingly.

When replacing a 2500 Steering Knuckle start by removing the tire and wheel and then remove the wheel drive shaft if equipped to the vehicle. Uture service of the lower Ball Joint. Unos the Wheel Bearing and hub assembly needs removal. Outer tie rod removal from the knuckle requires support of the lower Control Arm to prevent movement. First remove the upper Ball Joint from the knuckle and then separate the lower Ball Joint from the same component. When servicing the lower Ball Joint keep all brake and electrical components connected to the system. Attach the knuckle assembly to the vehicle's side while maintaining its position. Next step is to take the knuckle off the vehicle body. The first step for installation involves setting the knuckle on the lower Ball Joint before installing the upper Ball Joint. Following the connection of the outer tie rod to the knuckle you should install the Wheel Bearing and hub assembly. The original wheel drive shaft must be reinstalled when present. After removing the lower Control Arm support, install the tire and wheel to the vehicle.
