# How to Replace BMW E90 Rear Coil Springs.

Replacing the rear coil springs on your BMW E90 can seem daunting. However, with the right tools and a positive attitude, you can tackle this project confidently. This guide will walk you through the process step by step. You'll gain valuable insights along the way, ensuring a smoother ride and enhanced performance.

## Understanding Rear Coil Springs.

### Why Rear Coil Springs Matter.

Rear coil springs are essential components of your BMW's suspension system. They support the weight of the vehicle and help absorb shocks from the road. When these springs wear out, you may notice decreased comfort and handling issues. Replacing them not only rejuvenates your ride but also enhances safety.

### Signs of Worn Out Springs.

A few warning signs indicate it's time for a replacement. You may experience a sagging rear, excessive bouncing, or unusual noises when driving over bumps. If the ride quality has diminished, your springs might be the culprit.

## Tools and Preparation.

### Tools You'll Need.

Before you begin, gather the necessary tools. You'll need a jack, jack stands, a socket set, and a spring compressor. Having these tools on hand will make the process smoother and quicker.

### Prepare Your Workspace.

Choose a flat, well-lit area for the replacement. Ensure your car is parked on a stable surface, and always engage the parking brake. Safety should be your top priority throughout the process.

## Step-by-Step Replacement Process.

### Step 1: Lift the Vehicle.

Start by loosening the rear wheel lug nuts. Then, use a jack to lift the vehicle off the ground. Place jack stands under the vehicle to ensure it remains secure while you work.

### Step 2: Remove the Wheel.

Once the car is lifted securely, remove the rear wheel. This will provide better access to the suspension components.

### Step 3: Remove Old Springs.

Locate the coil spring. You will need to detach the shock absorber from the lower control arm. Use a socket wrench to unbolt it. Next, compress the spring using a spring compressor. Carefully remove the springs, ensuring you wear safety goggles.

### Step 4: Install New Springs.

Take your new coil springs and place them in the same location as the old ones. Make sure they seat properly. Once the springs are in place, reattach the shock absorber.

### Step 5: Reassemble.

Now it's time to reassemble your vehicle. Replace the rear wheel and tighten the lug nuts. Carefully lower the vehicle back to the ground.

## Final Touches.

### Safety Checks.

After the installation, double-check all connections. Ensure everything is secure and properly tightened. A quick test drive can help determine if the new springs function correctly.

### Enjoy Your Newly Improved Ride.

Replacing your BMW E90's rear coil springs will significantly improve its performance. Enjoy a smoother ride and better handling on the road. The effort you put into this project will be well worth it.

## Conclusion.

Replacing the rear coil springs on your BMW E90 is not only a rewarding experience but also a practical one. With careful preparation, the right tools, and a step-by-step approach, you can enhance your vehicle's performance. Embrace the challenge, and you'll find that your BMW rides better than ever.
