Let’s dive into the tools, parts, and techniques required to get your Fusion back to its original ride quality.
We will cover the specific nuances of the Ford CD4 platform, ensuring you have the “pro tips” needed to avoid common pitfalls. From accessing the hidden top mounts to choosing the right damping technology, this article serves as your comprehensive resource for suspension maintenance.
Understanding the Role of Your 2016 ford fusion rear shocks
The rear suspension on a 2016 Ford Fusion is a sophisticated multi-link design that prioritizes both comfort and handling. Unlike older vehicles with solid axles, your Fusion uses independent rear suspension where the shocks and springs are mounted separately. This design allows for better wheel control but means the shocks take a significant amount of abuse from daily road imperfections.
A shock absorber’s primary job is not to support the vehicle’s weight; that is the job of the coil spring. Instead, the shock “dampens” the energy stored in the spring. Without functional shocks, your car would continue to bounce long after hitting a bump, leading to a “floaty” feeling that makes the car feel disconnected from the pavement.
Internal valves inside the shock body control the flow of hydraulic fluid. As the piston moves up and down, this fluid creates resistance. Over time, the seals inside your 2016 ford fusion rear shocks can fail, or the internal fluid can degrade, leading to a loss of damping force that you will feel through the chassis.
Signs Your Shocks Need Replacement
One of the most obvious signs of failure is “cupping” on your rear tires. If you run your hand over the tread and feel high and low spots, your shocks are no longer holding the tire firmly against the road. This creates a rhythmic humming noise while driving that many people mistake for a bad wheel bearing.
You should also perform a visual inspection for hydraulic fluid leaking down the side of the shock body. A light “misting” is sometimes considered normal by manufacturers, but a heavy coat of wet oil indicates a blown seal. Once the fluid is gone, the shock can no longer provide the resistance needed to stabilize the vehicle.
Finally, pay attention to “rear-end squat” during hard acceleration or “nose-dive” during braking. If the rear of the car feels like it is swaying or “fishtailing” slightly when you hit a mid-corner bump, your 2016 ford fusion rear shocks are likely shot. Replacing them will immediately sharpen the steering response and make the car feel more planted.
Step-by-Step Guide to Replacing 2016 ford fusion rear shocks
Replacing the shocks on this specific model is a task that most DIYers can complete in about two hours. Unlike the front struts, you do not need a spring compressor for the rear shocks because the coil spring is located on the lower control arm. This makes the job significantly safer and more straightforward for those working in a home garage.
Before you begin, ensure you have a flat, level surface to work on. Safety is the most important part of any automotive repair. Always use high-quality jack stands and never rely solely on a floor jack to hold the weight of the vehicle while you are working underneath it.
Tools and Materials You Will Need
Gathering your tools beforehand will prevent frustration mid-job. For the 2016 Fusion, you will need a 15mm deep socket for the lower mounting bolt and a 13mm socket for the upper mount nuts. A 10mm socket or a trim removal tool will also be helpful for moving the wheel well liner out of the way.
- Floor jack and two heavy-duty jack stands.
- 1/2-inch drive torque wrench.
- 13mm and 15mm sockets (deep and shallow).
- Penetrating oil (like PB Blaster or WD-40 Specialist).
- New 2016 ford fusion rear shocks (sold in pairs).
- Replacement upper mounts (highly recommended).
Preparing the Vehicle
Start by loosening the lug nuts on the rear wheels while the car is still on the ground. Once loosened, jack up the rear of the vehicle using the factory-approved lift points. Place your jack stands under the subframe or the reinforced pinch welds to ensure the car is stable.
Remove the rear wheels and set them aside. It is often helpful to spray the lower shock bolt with penetrating oil at this stage. These bolts are exposed to road salt and moisture, which can cause them to seize in the lower control arm bushing. Letting the oil soak for 15 minutes can save you from a broken bolt later.
Accessing the Upper Mounts
On the 2016 Ford Fusion, the top of the shock is attached to a cast aluminum mount, which is then bolted to the chassis. To reach these bolts, you will need to peel back the fabric wheel well liner. You do not need to remove the entire liner; just remove the 10mm screws and plastic clips near the top of the wheel arch.
Once the liner is pulled back, you will see two 13mm nuts holding the shock mount to the body. Use an extension on your ratchet to reach these comfortably. Do not remove them entirely yet; just loosen them so they are hand-tight. This keeps the shock from falling while you work on the bottom bolt.
Removing the Old Shock
Move to the bottom of the shock and remove the large 15mm bolt. If the bolt feels tight, use a breaker bar to get it moving. Once the bottom is free, go back to the top, remove the two 13mm nuts, and the entire shock assembly will slide out of the wheel well.
Inspect the old mount. If it is cracked or the rubber center is degraded, you should replace it. Most experts recommend installing new mounts whenever you install new 2016 ford fusion rear shocks to prevent “thumping” noises caused by old, compressed rubber. You will need to transfer the dust boot and bump stop to the new shock if they were not included in the kit.
Choosing the Best Replacement Shocks
When shopping for 2016 ford fusion rear shocks, you will encounter several different types of damping technology. The right choice depends on your driving style and how long you plan to keep the vehicle. For most owners, an OE-spectrum twin-tube shock provides the best balance of cost and comfort.
If you prefer a firmer, more “European” handling feel, look for mono-tube shocks. These designs use a high-pressure nitrogen gas charge to prevent the oil from foaming during aggressive driving. Brands like Bilstein or KYB often offer mono-tube upgrades that improve cornering stability without making the ride overly harsh.
For those who frequently carry heavy loads or passengers in the back, consider a load-adjusting shock. These feature a variable valving system that firms up as the shock is compressed further. This prevents the “saggy” look and maintains proper headlight aim when the trunk is full of gear or groceries.
Aftermarket vs. OEM Ford Parts
Genuine Ford (Motorcraft) shocks are designed specifically for the weight and spring rates of your Fusion. They offer a guaranteed fit and the exact ride quality the car had when it left the showroom. However, they can be more expensive than high-quality aftermarket options from reputable manufacturers.
Aftermarket brands like Monroe or Gabriel often provide “Quick-Shock” kits that include the mount and dust boot pre-assembled. This can be a huge time-saver for DIYers. Just ensure the parts are listed as a direct fit for the 2016 model year to avoid compatibility issues with the electronic parking brake wiring or suspension sensors.
Common Challenges and Pro Tips
One of the biggest challenges when working on the 2016 ford fusion rear shocks is dealing with the tight space inside the wheel well. If you find it difficult to get a wrench on the upper nuts, try using a “flex-head” ratchet. This allows you to bypass the angle of the liner and get a solid grip on the hardware.
Another “pro tip” involves the final tightening of the lower bolt. You should never fully torque the lower shock bolt while the car is in the air. If you tighten it while the suspension is hanging, the rubber bushing will be “pre-loaded” once you drop the car. This leads to premature bushing failure and a squeaky suspension.
Instead, snug the bolt up, then lower the car onto its wheels or use a floor jack to compress the suspension to “ride height.” Only then should you apply the final torque. For the 2016 Fusion, the lower shock bolt torque spec is typically around 85 lb-ft, but always verify with your specific service manual.
Dealing with Seized Bolts
If the lower bolt refuses to budge, do not force it with an impact wrench immediately. This can snap the bolt head off, leaving the shank stuck inside the bushing. Instead, use a combination of heat from a propane torch and more penetrating oil. The heat causes the metal to expand, breaking the bond of the rust.
If the bolt is truly stuck, you may need to replace the entire lower control arm. To avoid this, many mechanics apply a thin layer of anti-seize lubricant to the shank of the new bolt before installation. This ensures that if you ever need to perform this repair again, the parts will come apart easily.
Frequently Asked Questions About 2016 ford fusion rear shocks
How long do the rear shocks typically last on a Ford Fusion?
Most factory shocks begin to show signs of significant wear between 50,000 and 80,000 miles. However, if you drive on rough gravel roads or frequently hit large potholes, they may fail as early as 30,000 miles. It is good practice to inspect them during every oil change for leaks or damage.
Do I need an alignment after replacing the rear shocks?
On the 2016 Ford Fusion, replacing the rear shocks does not typically alter the camber or toe settings because the shock is not a structural part of the alignment geometry. However, if your old shocks were so worn that they caused uneven tire wear, a professional alignment is recommended to ensure your tires last as long as possible.
Can I replace just one shock if only one is leaking?
It is highly recommended to replace shocks in pairs. Shocks wear out at roughly the same rate. If you replace only one, the difference in damping between the old and new shock can cause unpredictable handling and uneven braking. For a balanced ride, always do both sides of the same axle at once.
What is the difference between a shock and a strut?
A strut is a structural part of the suspension that also acts as a pivot point for the steering and holds the coil spring. A shock, like the ones found on the rear of your 2016 Fusion, simply dampens movement and is not a structural support for the vehicle’s weight. This makes shocks much easier to replace for the average DIYer.
Final Thoughts on Suspension Maintenance
Taking the time to maintain your 2016 ford fusion rear shocks is one of the most cost-effective ways to keep your car feeling new. A fresh set of dampers will not only improve your comfort but also protect other suspension components, like ball joints and bushings, from excessive vibration and stress.
Remember to always prioritize safety by using the correct jack points and torque settings. If you feel uncomfortable at any point during the process, especially when dealing with rusted hardware, do not hesitate to consult a professional mechanic. However, for most, this is a rewarding weekend project that provides immediate results you can feel the moment you back out of the driveway.
By following the steps outlined in this guide, you are ensuring that your Ford Fusion remains a reliable and enjoyable vehicle for years to come. Keep an eye on your tire wear, listen for unusual noises, and enjoy the renewed stability of your ride. Stay safe and stay comfortable!
