Note: If the drive shaft mounting bolt is loosened more than 90°, the wheel bearing must not be loaded with the weight of the vehicle, i.e. the vehicle must not be standing on the wheels. If the wheel bearing is loaded with the weight of the vehicle when the drive shaft mounting bolt is loosened, the inner bearing will be damaged, which will reduce its service life. If the vehicle must be mounted on the wheels or moved, the following must be observed: Install the outer joint instead of the cardan shaft. Tighten the mounting bolt (use old) outer CV joint with a torque of 120 Nm.
Remove the drive shaft-to-hub mounting bolt. Remove the wheel. Remove the brake pipe and electrical wire bracket and set it aside. Remove the bracket with the brake caliper and tie it to the body with wire. Remove the ABS speed sensor. Remove the brake disc. Remove the shield from the steering knuckle. Loosen the tie rod end nut a few turns, but do not remove it.
Note: To protect the threads, leave the ball joint nut threaded onto the top few threads of the stud.
Using the ball joint puller "3287A", press the ball joint out of the steering knuckle. Now you can unscrew the nut. Pull the drive shaft out of the wheel hub as much as possible (towards the checkpoint).
On a vehicle with automatic headlight corrector, unscrew nut "1" of the left front ground clearance sensor "G78".
Unscrew the nuts securing the "arrow". Press out the ball joint from the triangular lever. Place the "VAG 1383A" engine and transmission jack under the steering knuckle.
Loosen the bolt connecting the steering knuckle and the shock absorber strut "arrow".
Insert spacer "3424" into the slot of the steering knuckle. Turn it with a ratchet wrench by 90° and remove the wrench from spacer "3424". Remove the steering knuckle from the shock absorber strut.
Installation
Installation in reverse order. Tighten the drive shaft to hub mounting bolt. After replacing the steering knuckle, it is necessary to adjust the wheel alignment angles.
