Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the CV joints for torn boots or damage. Replace if necessary.
Check the tie rod ends and ball joints for any signs of wear. If there is excessive play, replace the affected components.

4. Inspect the Steering Rack

Check the steering rack for any signs of leaks or damage.
If the steering rack is damaged, disconnect the steering shaft and remove the rack from the vehicle for replacement.

5. Reassemble and Test

Reinstall any components that were removed for inspection.
Ensure all nuts and bolts are torqued to the manufacturer’s specifications.
