Shock Absorber Replacement Rear – 2012-2019 BMW 3 Series Sedans (F30)
Step 1 - Purchase Parts

Rear Shock Absorber with Electronic Damper Control (EDC)
These OE replacement shocks are manufactured by Bilstein and have been specifically engineered to meet or exceed BMW factory standards. Please be aware that many BMW models were manufactured with or without EDC rear shocks. The best way to verify if your rear shocks have EDC is to look at the base of the shock where it attaches to the rear axle - if you see a wire plugged into a module attached to the shock, then your vehicle has EDC and this is the correct replacement part.

Rear Shock Absorber
These rear shock absorbers are for BMW vehicles that do not have Electronic Damper Control. They are Genuine BMW, which means they deliver factory performance and are the same shock absorbers that would be installed at the dealership.

Rear Upper Shock Mount
One of the most common sources of noise emanating from the rear suspension are worn shock mounts. The noise can be anything from a "grind" to a "thud"...especially when going around corners. The rear shock mounts attach the shock absorber to the body of the vehicle, and new ones should always be installed when replacing the rear shock absorbers on your BMW.
Step 2 - Repair Procedure

- Remove the front wheels.
- Locate the rear camber cover (2). Unscrew the four nuts anchoring it to the rear axle and remove it from the vehicle.

- If the vehicle is equipped with electronic damper control (EDC), unplug the adapter wire (1) remove its wiring harness from the rear shock absorber.

- Use a floor jack to support the rear trailing arm. Loosen the nut on the lower shock mounting bolt (1) shown in the image.
- Use the floor jack to raise the trailing arm until there is enough slack to remove the lower shock mounting bolt from the rear axle.
- Slowly lower the floor jack and remove from underneath the vehicle.

- Remove the three upper shock mounting bolts anchoring the shock absorber to the body of the vehicle.

- Compress the shock absorber, then rotate out and up out of the vehicle.

Important torque values:
Upper shock mounting bolts - 30 Nm (22 ft-lb)
