Lower Ball Joint

Start your 4wd lower Ball Joint replacement by lifting the car and supporting it before you take off the tire and wheel. Take off the Torsion Bar and take out the wheel drive shaft. Begin by drilling 1/8-inch diameter holes for 1/4-inch deep through the lower Ball Joint rivets before eliminating their heads using a 1/2-inch drill. You need to use a pin punch to push out the rivets as you take out the lower Ball Joint from its position in the Control Arm below. After setting the new lower Ball Joint in the Control Arm, follow the fastener notice in service precautions before installing bolts and nuts. Tighten lower Ball Joint nuts to 23 nm (17 ft. Lbs.) according to specifications. Replace the drive shaft wheel along with the loaded torsion member into the vehicle before installing the tire and wheel and then lowering the car. During the final step examine the wheel's position first of all.

Start servicing the lower Ball Joint by raising and supporting the vehicle before taking off its tire and wheel components. After taking off the Torsion Bar you should remove the wheel drive shaft from its position. Start with a 3.175mm (1/8 inch) drill to make a 6.35mm (1/4 inch) deep hole at the center of lower Ball Joint rivet. Shift to a 12.7mm (1/2 inch) drill to remove the rivet heads. Push the pin punch through each rivet to unfasten them before taking the lower Ball Joint out of the Control Arm. Slip the lower Ball Joint onto its position on the lower Control Arm while keeping to the fastener notice instructions. Connect the lower Ball Joint bolts and nuts then tighten them to 23 nm (17 ft. Lbs.) torque. Put the wheel drive shaft back and position the Torsion Bar before putting tire and wheel together. After putting the vehicle down end to end check the front wheel alignment.

You need to lift and support the vehicle before taking off its tire and wheel to replace the lower Ball Joint. First release the Torsion Bar and extract the wheel drive shaft parts. Rephrase verbalization by using a smaller drill before a bigger drill to prepare each rivet for easy removal. Drill a centerpoint 6.25 mm deep with 3.175 mm drill bit before adding the rivet heads to the 12.7 mm drill bit. Push the pin punch through the rivets to get the lower Ball Joint out of the lower Control Arm assembly. When installing the system put the lower Ball Joint over the lower Control Arm while keeping to the fastener notice as detailed in the service precautions section. Fasten the lower Ball Joint bolts while tightening its retaining nuts to 23 nm. Insert the wheel shaft into place and lift the vehicle using the lifting device before sliding in the Torsion Bar and putting on the wheel and tire. Complete the assessment with the wheel alignment test.

Before starting the lower Ball Joint replacement on a 4wd you must lift the vehicle and secure it while taking off the tire and wheel. Take off the Torsion Bar parts and separate the wheel drive shaft. Make a 1/8 inch pilot hole 1/4 inch deep at the center of each lower Ball Joint rivet before removing the rivet heads with a 1/2 inch drill. Use a pin punch tool to get rid of the rivets and remove the lower Ball Joint from the lower Control Arm. After fitting the new lower Ball Joint onto the lower Control Arm according to service precautions, tighten the lower Ball Joint retaining nuts to 23 nm using the recommended fastening process. Reconnect the wheel drive shaft and put back the Torsion Bar before mounting the tire and wheel assembly then lower the car. End the repair process by inspecting wheel alignment at the front.

Load the torsion bar, reinstall the tire and wheel, lower the vehicle, and inspect the front wheel alignment.

Drill a 6.35 mm (1/4 inch) deep hole in the center of each rivet using a 3.175 mm (1/8 inch) drill, then drill the rivet heads away with a 12.7 mm (1/2 inch) drill and remove the rivets with a pin punch.

Check the upper ball joint for wear by disconnecting it from the steering knuckle and replacing it if any looseness is detected.

Secure them with the mounting bolt and nut tightened to 24 Nm (18 ft. lbs.).

Drill a 6.35 mm (1/4 inch) deep hole in the center of each rivet with a 3.175 mm (1/8 inch) drill, then drill the rivet heads away using a 12.7 mm (1/2 inch) drill, and finally, remove the rivets with a pin punch.

Attach the upper ball joint to the steering knuckle and tighten the retaining nut to 83 Nm (61 ft. lbs.), ensuring it is aligned for the cotter pin without over-tightening.
