You can Select Your Vehicle to check if 31316786002 fits your vehicle.

Block the rear wheels, apply the parking brake, raise the front of the vehicle, support it on jackstands, and remove the appropriate wheel. Remove the fasteners and the engine under-shield. Take off the brake disc. Trace the wiring to disconnect the ABS wheel speed sensor and brake pad wear sensor, then unclip the wiring. Detach the ride height sensor rod from the control arm, if equipped. Loosen the bolt connecting the control arm to the front subframe. Detach the control arm, tension strut, and tie-rod end from the hub carrier. While counterholding the ball joint shank, remove the stabilizer bar link nut, discard it, and note that the brake hose bracket is retained by this nut. Support the hub carrier with a floor jack. For models with strut tower braces, remove the cowl trim panel cap and the associated bolts. For all models, from within the engine compartment, remove the strut upper mounting nuts and lower the strut assembly. Note alignment marks between the mounting plate and vehicle body. Once the strut is removed, clean it and mount it upright in a vise. Remove the bolt attaching the suspension strut to the hub carrier, and the ABS sensor wiring bracket. Then, using a spring compressor, compress the coil spring. Access the strut upper mount retaining nut, remove it, and take off the associated components. Inspect all parts for wear or damage, replacing as necessary. Check the strut and coil spring for any signs of damage. Reassemble the strut, ensuring all parts are correctly positioned. During installation, tighten all fasteners to their specified torque, replace self-locking nuts, and once completed, it's recommended to check the front wheel alignment and steering angle sensor calibration if the vehicle has active steering.

If you observe signs of wear or damage on the shock absorber, it's advisable to replace it. Also, inspect other components for damage or deterioration and replace them as needed.

The shock absorber check involves parking the vehicle on level ground, checking tire pressures, pushing down at each corner of the vehicle to observe the movement of the body, and determining if a worn or weak shock absorber is the cause.

Start by loosening the bolt that connects the control arm to the front subframe. Then, detach the control arm, tension strut, and tie-rod end from the hub carrier. While counterholding the ball joint shank, remove the stabilizer bar link nut. It's important to note that this nut also retains the brake hose bracket.

Attach the shock absorber upper mount to the subframe using new self-locking nuts, and avoid mixing shock brands on a single axle by using the BMW part number to match manufacturers.

During reassembly, ensure that all parts are correctly positioned. Inspect all components for wear or damage and replace them if necessary. Be diligent in tightening all fasteners to their specified torque and consider replacing self-locking nuts. After completing the reassembly, it's recommended to check the front wheel alignment and, if applicable, calibrate the steering angle sensor, especially if the vehicle has active steering.

Yes, on F30, F31, and F34 chassis, remove the cover from the camber arm and loosen the shock absorber lower bolt/nut. Remove the three mounting bolts from the top of the shock absorber. Lower the jack and remove the shock absorber through the wheel well.

After removing the upper mounting nut, lower the shock absorber out from underneath the vehicle. If needed, you can also remove the two bolts and the mounting from the suspension arm.

Disassemble and reassemble the strut assembly on a bench.

The steering and suspension check includes inspecting tires for irregular wear patterns and proper inflation, checking the universal joint and steering gear housing for leakage, examining tie-rod ends and all suspension and steering components for damage or wear, testing the movement of the steering components while an assistant turns the steering wheel, checking balljoints for play and inspecting their boots for damage, and inspecting the suspension arm bushings at the rear of the vehicle for deterioration.

No, avoid using an impact tool for tightening the strut nut.

The front suspension shock absorbers on 3-Series models are MacPherson struts.
