How to Replace BMW E90 Rear Coil Springs

Replacing the rear coil springs on your BMW E90 can improve both handling and ride comfort. Whenever you notice signs of wear, such as decreased performance or a sagging rear end, it’s essential to address these issues promptly. This guide will walk you through the steps required for a successful coil spring replacement.

Tools and Materials Needed

Before you begin the replacement process, gather the essential tools and materials. Here’s what you will need:

• Jack and jack stands
• Socket set
• Spring compressors
• New rear coil springs
• Pry bar (optional)

Step-by-Step Process

1. Safety First

Park your BMW E90 on a flat, stable surface and engage the parking brake. To ensure maximum safety, wear protective goggles and gloves throughout the process.

2. Lift the Vehicle

Using the jack, lift the rear of the vehicle and place jack stands under the support points to secure it. This allows you to access the rear suspension safely.

3. Remove the Wheels

Next, remove the rear wheels using the socket set. This gives you clear access to the coil springs and suspension components.

4. Compress the Old Springs

Before removing the old coil springs, you must use spring compressors to safely compress them. This is crucial, as uncompressed springs can explode out violently when removed. Attach the compressors evenly on the coil springs to compress them carefully.

5. Remove the Old Coil Springs

Once the springs are compressed, you can detach the bottom and top mounts. Carefully lower the compressed springs to release tension and remove them from the vehicle.

6. Install New Coil Springs

Now it's time to install the new coil springs. Place the new coil springs into their respective positions and ensure they fit snugly against the mounting points. Use the spring compressors again to secure the springs before reattaching the mounts.

7. Reassemble and Test

After securing the new coil springs, reattach the wheels and lower the vehicle back to the ground. Make sure to check that everything is tight and properly aligned. Finally, take the car for a test drive to feel the difference in handling and ride quality.
