How to Change a Wheel Bearing (long and detailed version)

Introduction

This tutorial will guide you through the process of changing a pressed wheel bearing in a 1995 Ford Windstar. The steps outlined here can be applied to most vehicles with similar pressed bearings. Replacing a wheel bearing can save you a significant amount of money, potentially $400 to $1000, and is manageable for amateur mechanics.

Step 1: Gather Tools and Safety Precautions

• Tools Required:

  • Flathead screwdriver
  • Ratchet and socket set (15mm, 18mm, 21mm, 30mm)
  • Breaker bar
  • Hammer
  • Torque wrench
  • Bearing press tool (recommended)
  • Pliers (needle nose)
  • Bungee cord or rope
  • Safety glasses and gloves

• Safety Precautions:

  • Ensure the vehicle is on a flat surface.
  • Use wheel chocks on the rear wheels.
  • Engage the parking brake.

Step 2: Remove the Wheel and Access Components

1. Remove the Wheel:

   • Use a flathead screwdriver to remove the cover from the wheel hub.
   • Loosen the spindle nut using a ratchet and a long metal bar for leverage.
   • Lift the vehicle and remove the tire.

2. Detach the Brake Caliper and Rotor:

   • Use PB Blaster or liquid wrench on the caliper bolts.
   • Remove the two caliper bolts (15mm).
   • Hang the caliper using a bungee cord to avoid straining the brake line.
   • Remove the brake rotor.

Step 3: Remove the Axle and Steering Components

1. Remove the Axle:

   • Unscrew the axle nut and remove the washer.
   • Check for play in the bearing to confirm it's bad.

2. Detach the Lower Control Arm:

   • Remove the ball joint nut (18mm).
   • Use a hammer to lightly tap and loosen the ball joint.
   • Push down on the control arm to free the ball joint.

3. Remove the Tie Rod:

   • Take off the castle nut from the tie rod.
   • Remove the nut connecting the tie rod to the steering knuckle.

4. Detach the Strut:

   • Remove the ABS sensor using an 8mm socket.
   • Remove the strut bolt (21mm).

Step 4: Remove the Steering Knuckle and Old Bearing

1. Remove the Steering Knuckle:

   • After detaching all connections, gently pull the steering knuckle off.
   • Set it on a stable surface for bearing removal.

2. Remove the Old Bearing:

   • Use a hammer to tap out the old bearing.
   • Clean the area to ensure no debris remains before installing the new bearing.

Step 5: Install the New Bearing

1. Prepare for Installation:

   • Lightly grease the inside of the steering knuckle where the new bearing will sit.

2. Press in the New Bearing:

   • Use a bearing press tool to ensure even installation.
   • Center the bearing and tighten the press slowly until the bearing is fully seated.

Step 6: Reassemble the Steering Knuckle

1. Install the Hub and Spindle:

   • Grease the hub lightly before pressing it into the bearing.
   • Use the bearing press tool again to install the hub.

2. Reconnect All Components:

   • Reattach the strut, lower ball joint, and tie rod.
   • Ensure all bolts are snug but not fully torqued yet.

Step 7: Torque Specifications and Final Assembly

• Torque Values:

  • Strut bolt: 95-100 ft-lbs
  • Tie rod nut: 35-46 ft-lbs
  • Lower ball joint: 46-52 ft-lbs
  • Axle nut: 190-200 ft-lbs

• Final Steps:

  • Reattach the brake rotor and caliper.
  • Ensure all connections are secure and properly torqued.
  • Reinstall the wheel and lower the vehicle.

Conclusion

You have successfully changed the wheel bearing on your 1995 Ford Windstar. This process involves careful disassembly and reassembly, but with the right tools and patience, it is achievable.
