2012 Ford Fusion Steering Gear Replacement

The 2012 Ford Fusion, representing the last year of its first-generation facelift, remains a popular choice for its blend of affordability, fuel efficiency, and available features. However, like any vehicle, it's prone to certain issues as it ages. One area that can require attention is the steering gear, also known as the steering rack or steering box. This article provides a comprehensive guide to understanding steering gear replacement in a 2012 Ford Fusion, covering everything from symptoms and diagnosis to replacement procedures and aftercare.

Understanding the 2012 Ford Fusion Steering System

The 2012 Fusion utilizes a power-assisted rack-and-pinion steering system. The steering rack is a crucial component that translates the rotational motion of the steering wheel into linear motion that steers the wheels. Power assistance, typically provided by a hydraulic pump (in earlier models) or an electric motor (in later trims or hybrid versions), reduces the effort required to turn the wheel. When the steering gear fails, steering becomes difficult, imprecise, and potentially unsafe.

Symptoms of a Failing Steering Gear

Identifying a failing steering gear early can save you from more extensive damage and potential accidents. Common symptoms include:

Excessive play in the steering wheel: This means the steering wheel can be turned significantly before the wheels respond.
Difficulty steering: The steering wheel may feel stiff or require excessive force to turn, especially at low speeds.
Unusual noises: Grinding, clunking, or whining noises coming from the front of the car while turning the steering wheel. A failing power steering pump can also cause whining noises, so proper diagnosis is critical.
Vibrations in the steering wheel: This could indicate internal damage within the steering rack or worn tie rod ends (which connect to the steering rack).
Leaking power steering fluid: A leak in the steering rack seals can lead to fluid loss and reduced power steering assistance. Check for puddles of reddish-brown fluid under the car, near the front wheels.

Diagnosis and Inspection

A thorough diagnosis is essential before replacing the steering gear. Start by visually inspecting the steering rack for leaks and damage. Check the power steering fluid level and condition. Examine the tie rod ends and ball joints for excessive play. Using a scan tool, check for any diagnostic trouble codes (DTCs) related to the power steering system. If you're not comfortable performing these checks yourself, consult a qualified mechanic.

Steering Gear Replacement Procedure

Replacing a steering gear is a moderately complex job that often requires specialized tools and a good understanding of automotive mechanics. While some experienced DIYers may attempt this repair, it is generally recommended that it be performed by a professional. The general steps involved include:

Disconnect the battery: This prevents electrical shorts during the repair.
Raise and support the vehicle: Use jack stands to safely elevate the car.
Remove the front wheels: This provides access to the steering components.
Disconnect the tie rod ends: Use a tie rod end puller to separate the tie rod ends from the steering knuckles.
Disconnect the steering shaft: Disconnect the steering shaft from the input shaft of the steering rack.
Disconnect power steering lines: Carefully disconnect the power steering lines from the steering rack, being prepared for fluid spillage.
Remove the steering rack: Unbolt the steering rack from the vehicle and carefully remove it.
Install the new steering rack: Align the new steering rack and bolt it into place.
Reconnect the power steering lines, steering shaft, and tie rod ends: Ensure all connections are secure.
Bleed the power steering system: Follow the manufacturer's instructions for bleeding the power steering system to remove air bubbles.
Reinstall the front wheels and lower the vehicle.
Perform a wheel alignment: This is crucial to ensure proper handling and tire wear after replacing the steering gear.

Parts and Cost

The cost of a replacement steering gear for a 2012 Ford Fusion can vary depending on the manufacturer, whether it's new or remanufactured, and the specific model trim (e.g., hybrid vs. non-hybrid). Expect to pay anywhere from $200 to $800 for the part alone. Labor costs can add another $400 to $800, bringing the total repair cost to between $600 and $1600. Always get a quote from a reputable mechanic before proceeding with the repair.

Aftercare and Maintenance

Following the steering gear replacement, regular maintenance is crucial to prolong its life. This includes:

Checking the power steering fluid level regularly: Top up as needed with the correct type of fluid.
Inspecting the steering components for leaks and damage: Catching problems early can prevent more extensive repairs.
Performing regular wheel alignments: This helps to minimize stress on the steering system and ensure even tire wear.

By understanding the steering gear system in your 2012 Ford Fusion, recognizing the symptoms of failure, and following proper maintenance procedures, you can ensure safe and reliable steering performance for years to come.
