Replacing the upper bearing in a GM tilt steering column is a crucial maintenance task that can improve steering performance and eliminate unwanted noise. This guide provides step-by-step instructions for the replacement process, ensuring you have the necessary information to complete the job effectively.

Understanding the Upper Bearing Replacement

The upper bearing in a GM tilt steering column is essential for smooth steering operation. Over time, this bearing can wear out, causing issues such as squeaking or looseness in the steering wheel. The target audience for this guide includes DIY mechanics and car enthusiasts who are looking to perform maintenance on their vehicles.

Tools and Materials Needed

Before starting the replacement, gather the following tools and materials:

  • Dremel tool or grinder
  • Punch or drift
  • Socket set
  • Screwdrivers (Phillips and flathead)
  • Replacement upper bearing
  • Epoxy or Loctite (optional for securing the new bearing)

Step-by-Step Replacement Process

1. Remove the Steering Wheel: Start by removing the steering wheel from the column. This may require a steering wheel puller if it is tightly fitted.

2. Disassemble the Column: Carefully disassemble the steering column by removing any retaining clips, screws, and covers. Pay attention to how parts are arranged for reassembly.

3. Access the Upper Bearing: Locate the upper bearing within the column assembly. You may need to grind away any lip that holds it in place using a Dremel tool.

4. Remove the Old Bearing: Use a punch to drive out the old bearing from its housing. Ensure you access any notches that allow for easier removal.

5. Install the New Bearing: Position the new upper bearing into the housing with the rolled edge facing inward. Use a socket or drift to seat it properly.

6. Reassemble the Column: Carefully reassemble all components in reverse order of disassembly. Make sure all clips and screws are securely fastened.

7. Test Functionality: Once reassembled, test the steering column to ensure smooth operation without any noise or looseness.

Important Considerations

  • Proper Orientation: Ensure that bearings are installed with their rolled edges facing inward to prevent damage.

  • Secure Installation: If necessary, use epoxy or Loctite to hold the new bearing in place, especially if you have ground away retaining lips during removal.

  • Check All Components: While replacing the upper bearing, inspect other components like springs and canceling cams for wear and replace them if needed.
