The 2008 Ford Edge requires periodic wheel bearing replacement to maintain optimal performance and safety. This guide will cover the essentials of wheel bearing replacement for both front and rear wheels of the 2008 Ford Edge.

Front Wheel Bearing Replacement

Replacing the front wheel bearing on a 2008 Ford Edge is a complex task that requires specific tools and mechanical expertise. Here's an overview of the process:

1. Lift the vehicle and remove the wheel

2. Disconnect the brake caliper and rotor

3. Remove the axle nut and ABS sensor

4. Separate the tie rod end and lower ball joint

5. Remove the hub assembly from the steering knuckle

6. Press out the old bearing and press in the new one

7. Reassemble all components in reverse order

Important note: Proper torque specifications must be followed for all bolts, especially the axle nut, which typically requires 203 foot-pounds of torque.

Rear Wheel Bearing Replacement

The rear wheel bearing replacement process differs slightly between front-wheel drive (FWD) and all-wheel drive (AWD) models:

FWD Models

For FWD models, the rear wheel bearing is typically part of a hub assembly that can be replaced as a single unit. The process involves:

1. Removing the wheel and brake components

2. Disconnecting the ABS sensor

3. Removing the hub assembly bolts

4. Installing the new hub assembly

AWD Models

AWD models may require additional steps, including:

1. Disconnecting the drive axle

2. Removing the backing plate

3. Pressing out the old bearing

4. Pressing in the new bearing

Caution: Special tools may be needed for pressing out and installing bearings on AWD models.

Tools Required

To replace wheel bearings on a 2008 Ford Edge, you'll need:

  • Jack and jack stands
  • Lug wrench
  • Socket set and ratchet
  • Torque wrench
  • Pry bar
  • Hub puller (for some models)
  • Press tool (for bearing installation)

For rear bearings on AWD models, a Torx bit set may be necessary to remove the four bolts holding the bearing assembly.

When to Replace Wheel Bearings

Consider replacing your Ford Edge's wheel bearings if you notice:

  • Grinding noise when driving
  • Steering wheel vibration
  • Uneven tire wear
  • ABS warning light illumination

Regular inspections during routine maintenance can help catch bearing issues early, preventing more extensive damage and ensuring your 2008 Ford Edge remains safe and reliable on the road.

FAQs About Wheel Bearings for 2008 Ford Edge

    • How long do wheel bearings typically last on a 2008 Ford Edge?
      Wheel bearings can last 80,000 to 100,000 miles under normal conditions, but this can vary based on driving habits and environmental factors.
    • Can I replace just one wheel bearing, or should I do them in pairs?
      While it's possible to replace a single bearing, many mechanics recommend replacing them in pairs (left and right side) for even wear and performance.
    • Is it safe to drive with a bad wheel bearing?
      Driving with a faulty wheel bearing is not recommended as it can lead to loss of steering control and potential wheel detachment in severe cases.
