2016 Ford Fusion Rear Shock Replacement – Restoring Smooth Ride
Replacing the rear shocks on a 2016 Ford Fusion is a straightforward DIY task that significantly improves vehicle stability and eliminates annoying suspension noise. By following a structured approach and using the right tools, you can restore your car’s original handling characteristics and save hundreds of dollars in professional labor costs.
If you have noticed your car bouncing excessively over speed bumps or felt the rear end “fishtail” on highway expansions, your suspension is likely compromised. Performing a 2016 ford fusion rear shock replacement is one of the most effective ways to regain control and ensure a safe, comfortable journey for you and your passengers.
In this guide, I will walk you through the entire process, from diagnosing the failure to torquing the final bolt. We will cover the specific tools you need and the expert tricks that make the job easier for a weekend mechanic. Let’s get your Fusion back to its factory-smooth ride.
Signs Your Rear Shocks Are Failing
Before you dive into the 2016 ford fusion rear shock replacement, you need to confirm that the shocks are actually the culprit. Shocks are responsible for dampening the energy of the springs; without them, your car would bounce uncontrollably like a pogo stick.
One of the most obvious signs is a leaking shock body. If you look behind the rear wheel and see a dark, oily film coating the shock absorber, the internal seal has failed. Once the hydraulic fluid escapes, the shock loses its ability to resist movement.
You should also pay attention to tire wear patterns. When shocks are worn, the tire doesn’t stay firmly planted on the pavement, leading to cupping or scalloped dips in the tread. This not only ruins your tires but also creates a loud humming noise while driving.
The Bounce Test
A classic way to check your suspension is the “bounce test.” Go to the rear corner of your Fusion and push down hard on the trunk, then let go. The car should rise and settle almost immediately.
If the vehicle continues to oscillate or bounce two or three times, the dampening force is gone. This lack of control can be dangerous during emergency maneuvers or heavy braking, as it shifts the vehicle’s weight unpredictably.
Essential Tools and Parts for the Job
Having the right tools on hand prevents frustration and keeps the project moving quickly. For a 2016 ford fusion rear shock replacement, you won’t need many specialized items, but a few high-quality basics are non-negotiable.
You will need a floor jack and a pair of sturdy jack stands. Never work under a car supported only by a hydraulic jack, as these can fail without warning. Safety should always be your first priority when working on suspension components.
In terms of hand tools, gather a 15mm socket for the top mount bolts and an 18mm socket for the lower mounting bolt. A 10mm socket or a trim removal tool will also be necessary to move the inner fender liner out of the way to access the upper hardware.
- Torque Wrench: Critical for ensuring bolts are tightened to factory specifications.
- PB Blaster or Liquid Wrench: A penetrating oil to loosen rusty or seized bolts.
- Brake Cleaner: Useful for cleaning the mounting surfaces before installation.
- Anti-Seize Lubricant: To prevent future corrosion on the lower mounting bolt.
Choosing Your Replacement Shocks
When shopping for parts, you will encounter various options ranging from budget-friendly twin-tube shocks to high-performance monotube designs. For a standard daily driver, a quality twin-tube shock from a reputable brand like Monroe or KYB is usually sufficient.
If you frequently carry heavy loads or want a firmer, more “connected” feel to the road, consider upgrading to a monotube shock. These handle heat better and provide more consistent dampening during spirited driving or long road trips.
Safety Procedures and Vehicle Preparation
Start by parking your Ford Fusion on a flat, level surface, such as a garage floor or a paved driveway. Engage the parking brake and place wheel chocks in front of the front tires to prevent the car from rolling while the rear is in the air.
Loosen the lug nuts on both rear wheels while the tires are still touching the ground. You don’t need to remove them yet; just break the initial tension so you aren’t fighting a spinning wheel later.
Position your floor jack under the rear jacking point or the rear subframe. Lift the vehicle high enough to allow the rear suspension to hang freely. Place your jack stands under the pinch welds or the frame rails and slowly lower the car onto them.
Clearing the Work Area
Remove the lug nuts and pull the wheels off, setting them aside or sliding them under the car for an extra layer of safety. You will now see the shock absorber tucked behind the wheel hub assembly.
The 2016 Fusion uses a fender liner that partially obscures the upper shock mount. You do not need to remove the entire liner, but removing a few 10mm bolts or plastic clips will allow you to peel it back enough to get a socket on the upper mounting bolts.
A Step-by-Step Guide to 2016 ford fusion rear shock replacement
Now that the vehicle is prepared, we can begin the actual 2016 ford fusion rear shock replacement. This process typically takes about 30 to 45 minutes per side, depending on how much rust you encounter.
Start by spraying the lower 18mm bolt with penetrating oil. This bolt is exposed to road salt and moisture, making it prone to seizing. Let the oil soak for a few minutes while you address the upper mounts.
- Remove the Upper Bolts: Use your 15mm socket and an extension to reach the two bolts holding the shock mount to the chassis. These are located at the very top of the shock assembly inside the wheel well.
- Unbolt the Lower Mount: Use your 18mm socket and a long breaker bar to loosen the bottom bolt. Support the bottom of the shock with your hand as you remove the bolt so it doesn’t drop suddenly.
- Extract the Old Shock: Pull the entire shock assembly out of the wheel well. On the 2016 Fusion, the shock and the upper mounting bracket usually come out as one unit.
- Transfer the Mount: If your new shocks did not come with a new upper mount, you will need to transfer the old one. Remove the nut at the very top of the shock rod while holding the rod with a wrench to keep it from spinning.
- Install the New Shock: Slide the new shock into the upper mount and tighten the top nut. Then, position the assembly back into the vehicle, starting with the two 15mm upper bolts.
Seating the Lower Bolt
Once the top is secure, align the bottom of the shock with the mounting hole on the knuckle. You may need to use your floor jack to slightly raise the suspension arm to get the holes to line up perfectly.
Apply a small amount of anti-seize to the threads of the 18mm bolt before sliding it through. Hand-tighten it first to ensure you don’t cross-thread the hole, which would be a very costly mistake to fix.
Choosing the Right Replacement Shocks: OEM vs. Aftermarket
One of the most common questions during a 2016 ford fusion rear shock replacement is whether to stick with original equipment manufacturer (OEM) parts or go with an aftermarket alternative. Both have distinct advantages depending on your goals.
OEM shocks are designed specifically for the Fusion’s weight and spring rates. They offer the exact ride quality the car had when it was new. If you were happy with the car’s performance for the first 50,000 miles, OEM is a safe and reliable choice.
Aftermarket shocks, however, often provide better value and specialized performance. Brands like Bilstein or Koni offer shocks that can improve handling and reduce body roll. These are excellent choices if you enjoy a more athletic driving experience or if you have modified your car with lowering springs.
Warranty and Longevity
Many high-quality aftermarket shocks come with a limited lifetime warranty. This means if the shock leaks or fails prematurely, the manufacturer will replace the part for free. This is a significant advantage over OEM parts, which typically only carry a 12-month or 12,000-mile warranty.
Regardless of the brand, always replace shocks in pairs. Even if only one side is leaking, the internal wear on the “good” side will be different from the brand-new side. Replacing both ensures a balanced ride and predictable handling in emergency situations.
Common Pitfalls and Troubleshooting During Installation
Even for experienced DIYers, a 2016 ford fusion rear shock replacement can present some challenges. The most common issue is the shock rod spinning while you try to tighten or loosen the top mounting nut.
To solve this, most shock rods have a flattened tip or a hex-shaped top. You can use a pair of locking pliers or a small wrench to hold the rod stationary while you turn the nut with an offset box-end wrench. Never grip the polished part of the shock rod with pliers, as any scratches will destroy the internal seals.
Another issue is rust. If the lower 18mm bolt refuses to budge, do not force it with an impact wrench immediately, as you might snap the bolt head off. Instead, apply heat with a propane torch to expand the metal, then try again with a breaker bar.
Torque Specifications Matter
It is tempting to just “get it tight,” but suspension components require specific torque to stay secure under the constant vibration of the road. For the 2016 Ford Fusion, the upper mounting bolts typically require around 22-25 lb-ft of torque.
The lower mounting bolt, which bears much more stress, usually requires a much higher torque, often around 70-80 lb-ft. Always verify these numbers in your owner’s manual or a repair guide to ensure the hardware doesn’t vibrate loose over time.
Frequently Asked Questions About 2016 Ford Fusion Rear Shocks
How long does a 2016 ford fusion rear shock replacement take?
For a DIYer with basic tools, the job usually takes between 1.5 to 2 hours for both sides. If you have access to an impact wrench and the bolts aren’t heavily rusted, you can likely finish the task in under an hour.
Do I need an alignment after replacing rear shocks?
Generally, no. Since the rear shocks on a 2016 Fusion are not part of a strut assembly and do not dictate the camber or toe settings, a 2016 ford fusion rear shock replacement will not alter your wheel alignment. However, if you notice uneven tire wear later, an alignment check is a good idea.
Should I replace the shock mounts too?
It is highly recommended. The upper shock mounts contain a rubber bushing that degrades over time. If you install new shocks on old, flattened mounts, you may still hear clunking noises over bumps. Most experts suggest replacing the mounts every time you replace the shocks.
Can I drive with a blown rear shock?
While the car will technically move, it is not safe. A blown shock reduces tire-to-road contact, increases braking distances, and makes the car difficult to control in corners. It also puts extra stress on other suspension components like bushings and ball joints, leading to more expensive repairs later.
Final Thoughts on Your Suspension Project
Completing a 2016 ford fusion rear shock replacement is a rewarding project that pays dividends every time you hit a bump in the road. You’ll notice an immediate improvement in how the car “sets” itself after a dip and a much quieter cabin environment.
Remember to double-check your work before taking the car for a test drive. Ensure all bolts are torqued to spec and that the fender liners are securely fastened. Once you’re back on the road, listen for any unusual noises and enjoy the renewed stability of your Fusion.
Taking care of your own maintenance not only builds your confidence as a DIYer but also ensures the job is done with the care and attention your vehicle deserves. Stay safe, take your time, and enjoy the smooth ride!
