REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Loosen the front wheel lugs. Block the rear wheels. Jack up the front of the vehicle, allowing the front suspension to hang, and safely support the vehicle on jackstands.
- Remove the front wheels. Remove the lower engine splash shield.
- Use a ball joint separator and disconnect the ball joint from the steering knuckle.
- Unbolt the lower control arm from the crossmember and remove it from the vehicle.
The ball joint cannot be separated from the control arm, but must be replaced as an assembly.
- If the stabilizer bar is to be removed, disconnect the tie rod from the knuckle, unbolt it and remove.
- Check all parts for wear and damage. Service as required.
- Use an inch pound torque wrench and check the ball joint torque. Nominal starting effort should be 22-87 inch lbs. Replace the assembly if otherwise.
- Install the stabilizer, if removed. Connect the tie rod. Position and attach the lower control arm to the crossmember. Connect the ball joint. Install the splash shield and front wheels. Lower the vehicle.
- Torque the mounting bolts as follows: Knuckle to Strut; 54-65 ft. lbs.; Lower Arm to Body; 118-125 ft. lbs.; Stabilizer Bar to Body; 12-20 ft. lbs.; Ball Joint to Knuckle; 44-53 ft. lbs.; Lower Arm to Shaft; 70-88 ft. lbs.
See Figure 4
- Raise and support the front end.
- Remove the wheels.
- Disconnect the stabilizer bar and strut bar from the lower arm.
- Remove the nut and disconnect the ball joint from the knuckle with a separator.
- Unbolt the lower arm from the crossmember.
- Check all parts for wear or damage and replace any suspect part.
- Using an inch lbs. torque wrench, check the ball joint starting torque. Starting torque should be 20-86 inch lbs. If it is not within that range, replace the ball joint.
Install the lower arm to the crossmember, Install the strut bar and stabilizer. Attach the front wheels and lower the vehicle. Tighten all fasteners with the wheels hanging freely. Observe the following torques:
Ball joint-to-knuckle: 44-53 ft. lbs.
When installing the stabilizer bar, the nut on the bar-to-crossmember bolts and the bar-to-lower arm bolts, are not torqued, but turned on until a certain length of thread is exposed above the nut: 2WD Stabilizer Bar to Crossmember: 8-10mm; Stabilizer Bar to Lower Control Arm: 8-10mm; 4WD Stabilizer Bar to Crossmember: 8-10mm; Stabilizer Bar to Lower Arm: 13-15mm.1992-93 Vista
See Figure 5
- Disconnect the negative battery cable.
- Raise the vehicle and support safely.
- Remove sway bar links from lower control arm.
- Disconnect the ball joint stud from the steering knuckle.
- Remove the inner mounting frame-through bolt and nut.
- Remove the rear mount bolts. Remove the clamp if equipped.
- Remove the rear rod bushing if servicing.
- Assemble the control arm and bushing.
- Install the control arm to the vehicle and install the through bolt. Replace the nut and snug temporarily.
- Install the rear mount clamp, bolts and replacement nuts. Torque the bolts to 51 ft. lbs. (70 Nm).
- Connect the ball joint stud to the knuckle. Install a new nut and torque to 43-52 ft. lbs. (60-72 Nm).
- Install the sway bar and links.
- Lower the vehicle to the floor for the final torquing of the frame mount through bolt.
- Once the full weight of the vehicle is on the floor, torque the frame mount through bolt nuts to 75-90 ft. lbs. (102-122 Nm).
- Connect the negative battery cable and align the front end.
