Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent accidental airbag deployment.

2. Inspect and Tighten Steering Column Bolts

Locate the steering column mounting bolts under the dashboard.
Using a socket set, check each bolt for tightness.
If loose, tighten each bolt to the manufacturer’s specifications (typically around 14-20 ft-lbs).
Re-check for any further play in the steering column.

3. Examine Intermediate Steering Shaft

Remove the plastic cover around the steering column to access the intermediate shaft.
Inspect for any visible wear or movement in the shaft.
If worn, replace the intermediate steering shaft with a new part.

4. Inspect Steering Rack Mounts

Raise the vehicle using a jack and secure it with jack stands.
Inspect the steering rack mounts for looseness or damage.
Tighten any loose bolts or replace the mounts if necessary.

5. Reassemble and Test

Reattach any plastic covers removed during the inspection.
Reconnect the battery.
Test the steering by turning the wheel and checking for any remaining play or noise.
