Replacing the rear coil springs on your 2010 Chevy Traverse can seem daunting, especially if you’re not an experienced mechanic. However, with the right tools, a bit of know-how, and a sprinkle of patience, you can tackle this job yourself. This guide will walk you through the necessary steps to ensure a successful replacement, all while saving you money on labor costs.

Why Replace the Rear Coil Springs?

Over time, the rear coil springs can wear out due to constant load and stress. Signs that your springs might need replacement include a sagging rear end, uneven tire wear, or a noticeable decrease in ride quality. If your Traverse is leaning to one side or if you hear clunking or banging noises when hitting bumps, it’s time to consider a replacement.

Tools and Materials Needed:

• New rear coil springs (ensure they are compatible with your 2010 Chevy Traverse)
• Jack and jack stands
• Socket wrench set
• Spring compressors
• Torque wrench
• Safety glasses and gloves
• Pry bar
• Lubricating spray (like WD-40)

Step-by-Step Guide to Coil Spring Replacement

Step 1: Prepare Your Vehicle

Start by parking your Chevy Traverse on a level surface. Engage the parking brake and ensure the ignition is off. Begin with loosening the lug nuts on the rear wheels but don’t remove them completely just yet. Raise the rear of the vehicle using a jack until the suspension is fully extended, then secure it with jack stands.

Step 2: Remove the Rear Wheels

Now that the vehicle is secure, remove the lug nuts completely and take off the rear wheels. This provides you with ample space to work on the suspension components.

Step 3: Remove the Shock Absorbers

Locate the shock absorber mounting bolts. Using a socket wrench, remove these bolts. It’s essential to be careful during this step, as the shocks are under tension. Set the shock absorbers aside—they will need to be reinstalled later.

Step 4: Compress the Springs

Before removing the coil springs, you’ll need to use spring compressors to ensure they are safely compressed. Attach the spring compressors evenly on the coil spring and tighten them gradually. This process is crucial to avoid injury and to safely free the coils from their mounts.

Step 5: Remove the Lower Control Arm

To gain access to the coil springs, it’s often necessary to remove the lower control arm. Locate the bolts securing the lower control arm to the chassis and the hub assembly, and using your socket wrench, remove these bolts. Be cautious; the control arm can be heavy. You might need a pry bar to help separate the control arm from its mount.

Step 6: Remove the Old Coil Springs

With the lower control arm disconnected and the spring compressed, you can now easily remove the old coil springs from their mounts. Carefully unwire the compressors and remove the springs. If they are rusted in place, applying a little lubricant might help break them free.

Step 7: Install the New Coil Springs

Place the new coil springs into their respective seats. Ensure they sit correctly—misalignment can lead to poor handling and premature wear. Once in place, use the spring compressors again to compress the springs slightly so they can fit into the control arm and upper mounts.

Step 8: Reattach the Lower Control Arm and Shock Absorbers

With the new springs installed, it’s time to reattach the lower control arm. Secure it with bolts, making sure everything aligns correctly. Afterward, reinstall the shock absorbers and tighten their bolts to the manufacturer’s specifications using a torque wrench.

Step 9: Reinstall Rear Wheels

Once all components are securely fastened, it’s time to put the rear wheels back on. Tighten the lug nuts hand-tight, and lower the vehicle back to the ground.

Step 10: Final Steps

After the vehicle is back on the ground, tighten the lug nuts in a crisscross pattern to ensure even pressure. Finally, perform a thorough inspection to ensure everything is installed correctly and securely. A test drive will help you gauge if the ride quality has improved and whether any unusual noises emerge.

Replacing the rear coil springs on your 2010 Chevy Traverse may seem like an overwhelming task, but with careful execution and attention to detail, you can handle it. Not only will you enhance your vehicle's ride quality, but you’ll also gain invaluable hands-on experience. Always remember, if at any point you feel unsure, consulting a professional mechanic is never a bad choice!
