You can Select Your Vehicle to check if 33526771729 fits your vehicle.

To remove the shock absorber, start by blocking the front wheels and raising the rear of the vehicle on jackstands. Remove the rear wheel for better access. On E-series chassis models, remove the luggage compartment side trim panel. Position a fioojack underneath the hub carrier and raise it to support the weight of the carrier. Loosen and remove the nut securing the shock absorber to the lower mount, counterholding the shock absorber shaft with a wrench. From within the luggage compartment, pry up the rubber cap and unscrew the upper mounting nut, counterholding the shock absorber shaft with a wrench. Lower the shock absorber out from underneath the vehicle. If necessary, remove the two bolts and remove the mounting from the suspension arm. 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, then lower the jack and remove the shock absorber through the wheel well. To inspect the shock absorber, remove the trim cap, bump stop, and protective tube. Check for signs of fluid leakage, pitting on the piston, and damage on the body. Test the operation of the shock absorber by moving the piston through a full stroke and short strokes, ensuring smooth and continuous resistance. Replace the shock absorber if there are any signs of wear or damage. Inspect other components for damage or deterioration and replace as needed. Slide the tube, bump stop, and cap onto the shock absorber. For installation, follow the reverse steps of removal, ensuring proper torque settings and alignment.

If your vehicle has a strut tower brace, remove the cowl trim panel cap and associated bolts. Regardless of the model, from within the engine compartment, remove the strut upper mounting nuts and lower the strut assembly. Be sure to take note of any alignment marks between the mounting plate and vehicle body.

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.

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.

Counterhold the piston rod with a suitable wrench while handling the washer plate, bump stop, damper protective tube, and rear shock absorber.

Raise the car and remove the front wheel.

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.

The coil spring should be positioned between the spring holders in a spring compressor, ensuring that three coils lie between them before compressing the spring.

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

Once the strut assembly is removed, clean it and securely mount it upright in a vise. Proceed to remove the bolt attaching the suspension strut to the hub carrier, as well as the ABS sensor wiring bracket. To safely work with the coil spring, use a spring compressor to compress it.
