Note. You will need new lower arm front ball joint nuts when installing.
Withdrawal
1. Support the rear wheels. Apply the parking brake. Raise the front of the car and place it on stands (cm. "Lifting and placing the car on supports"). Remove the relevant wheel.
2. Turn out screws and remove protection of a crankcase of the engine.
3. Turn out bolts and remove from under the car the cross amplifier (see chapter 2A).
4. On models with axle load sensors, remove the nut and remove the linkage bracket from the lower arm.
5. Turn away a nut of a spherical support of the lower lever and disconnect the lower lever from a rotary fist by means of a puller (pic. 5.5, a, b).
6. Turn out two bolts of fastening of a back support of the lower arm to a body (pic. 5.6).
7. Turn away a nut of the internal hinge of the lower arm and take out the lower arm from under the car. Be aware that the hinge may have a tight fit in the subframe. In this case, knock out the hinge.
Repair
8. Thoroughly clean the lower arm and surfaces in the area of its supports, removing all dirt and, if necessary, anti-corrosion coating. Then inspect the arm for cracks, deformation, or other signs of damage, paying special attention to the bearing bushes and ball joint. If it is necessary to replace the support bushings or the ball joint, the lower arm must be taken to a dealer or a specially equipped bus station. A hydraulic press and special spacer bushings are required to press out bushings or ball joints and install new elements.
Installation
9. Before installation, clean with a tap the threaded hole for the coupling bolt of the steering knuckle clamp, with which the fist is attached to the rack.
In the absence of an appropriate tap, you can clean the threaded holes using an old bolt by sawing a groove in it across the threads.
10. Make sure the ball pins and ball holes are clean and dry, then reinstall the lower arm.
11. Insert the inner pivot pin into the subframe and align the ball joint pin with the steering knuckle. If necessary, press in the ball joint pin using a jack under the lower control arm.
12. Screw a new nut onto the inner pivot pin and tighten it to the required torque.
13. Screw on a new nut of a spherical support and tighten it the demanded moment.
14. Screw in bolts of fastening of a back support of the bottom lever and tighten them the demanded moment.
15. On models with axle load sensors, install the sensor rod bracket on the lower arm and securely tighten the mounting nut.
16. Establish under the car the cross amplifier and tighten bolts of fastening the demanded moment.
17. Install the crankcase protection.
18. Install the wheel, lower the vehicle to the ground and tighten the wheel bolts to the required torque.
