BMW 31126763719 Hydrobearing

Raise the car and remove the wheel, then remove the control arm. Using a service press and appropriate tools, press the bushing out of the control arm. Clean the bushing bore and press in a new bushing, ensuring to draw in the rubber mount from the chamfered side of the control arm bore. Press the bushing in so it protrudes equally from both sides of the arm before installing the control arm.

Replace bushings in pairs by raising the car and removing the rear wheel, then support the rear wheel bearing carrier with a suitable jack. Remove the coil spring and the ride height sensor if equipped, followed by the swing arm. Using BMW special tools 33 4 462, 33 4 464, 33 4 463, 33 4 466, and 33 4 465, remove the bushing from the subframe. Compress the new bushing with tools 33 4 455, 33 4 456, 33 4 452, and 33 4 451, ensuring to align the rubber bushing slot with the center line mark during installation. Press the mount in as far as possible with tools 33 4 461, 33 4 463, 33 4 466, and 33 4 465, then remove tool 33 4 450 and draw in the rubber mount completely. The remainder of the installation follows the reverse order of removal, using new self-locking nuts and tightening fasteners to final torque only after lowering the vehicle and allowing the suspension to settle. Have the car professionally aligned upon completion of the job.
