Control Arm: Service and Repair

Front Lower Arm Removal/Installation

Special Tools Required
Ball joint remover, 28 mm 07MAC-SL00200

NOTICE: To avoid damage, do not strike aluminum parts with a metal hammer. If necessary, tap gently with a plastic tipped hammer.

NOTE: Bolts and nuts with the [star] mark are special corrosion-resistant Dacro fasteners. Use the same type if replacement is necessary.

1. Raise the front of the vehicle, and support it with safety stands in the proper location. Remove the front wheels.
2. Turn the front of the knuckle outward. Tap the driveshaft inward with a plastic hammer to allow space to install the special tool on the lower arm ball joint.
3. Remove the lower arm ball joint from the knuckle.





4. Remove the front lower arm cover (A).





5. Remove the flange bolts (A) and nut (B), and remove the beam under-cover (C) and the lower arm (D). Note the lengths of the bolts (1) is longer than (2), and (2) is longer than (3).
6. Install the lower arm in the reverse order of removal, and note these items:
- Be careful not to damage the ball joint boot when connecting the lower arm to the knuckle.
- Tighten all mounting hardware to the specified torque values.
- First install all the components and lightly tighten bolts and nuts, then raise the suspension to load the weight before fully tightening to the specified torques.
- Tighten the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
- Install a new cotter pin on the castle nut after torquing.
- Before installing the wheel, clean the mating surface of the brake disc and the inside of the wheel.
- Check the wheel alignment, and adjust it if necessary.
