How to Replace the Rear Coil Springs on a BMW E90

Replacing the rear coil springs of a BMW E90 can seem daunting, but with the right guidance, the process can be straightforward. Whether you're a seasoned DIY enthusiast or a novice, this guide will provide you with the necessary steps to complete the task with confidence.

Tools Required

Before diving into the replacement process, ensure you have the following tools at your disposal:

• Jack and jack stands
• Wrench set
• Spring compressor
• Pliers
• Lubricant

Procedure

1. Safety First

Begin by parking your BMW E90 on a flat surface and engaging the parking brake. It is crucial to ensure your vehicle is stable before lifting it with a jack.

2. Lifting the Vehicle

Use the jack to lift the rear of the vehicle. Once elevated, securely place jack stands underneath for added safety. Never work under a vehicle supported only by a jack.

3. Remove the Wheel

Using the wrench, remove the lug nuts and take off the rear wheel to access the coil spring effectively.

4. Disconnect the Shock Absorber

Before removing the coil spring, you'll need to disconnect the shock absorber. This may involve removing bolts or clips; ensure all components are stored safely as you progress.

5. Compressing the Spring

Next, utilizing a spring compressor, secure the coil spring. This step is vital as it relieves tension on the spring, making it safer to remove.

6. Remove the Old Coil Spring

With the spring compressed, you can now unmount the coil spring from its seating. It should slide out with minimal effort.

7. Install the New Coil Spring

Take your new coil spring and install it in the same position as the old one. Make sure it is properly seated before releasing the tension from the spring compressor.

8. Reassemble Components

After the new coil spring is in place, reattach the shock absorber and ensure all bolts and clips are securely fastened. Replace the wheel and tighten the lug nuts.

9. Lower the Vehicle

Once everything is reassembled, carefully lower the vehicle back to the ground and remove the jack stands. Your BMW E90 is now equipped with new rear coil springs, ready for driving!
