Step-by-Step Guide to Replace BMW 1 Series Front Coil Springs

Step 1: Prepare Your Vehicle

Park on a flat surface and engage the parking brake. Loosen the lug nuts on both front wheels and lift the vehicle using a jack. Secure it with jack stands for safety.

Step 2: Remove the Front Wheels

Completely detach the lug nuts and take off the front wheels. This step allows greater access to the suspension components.

Step 3: Disassemble the Suspension Components

Remove the brake calipers and rotor as well as the sway bar links. This can typically be accomplished with basic socket tools. Label any bolts or components you remove for easier reassembly.

Step 4: Use Spring Compressors

Install the spring compressors on the coil springs to safely compress them. Ensure they’re evenly tightened to prevent instability. Then, remove the strut assembly from the vehicle.

Remove the old coil springs from the strut assembly by loosening the top nut. Install the new coil springs in reverse order, ensuring they’re seated correctly.

Step 6: Reassemble and Test Drive

Once the new coil springs are in place, reattach the strut assembly, braking components, and wheels. Lower the vehicle and torque all bolts to the manufacturer’s specifications. Test drive to ensure proper function.
