Solution

1. Preparation

Gather tools and materials necessary for the inspection.
Ensure the vehicle is parked on a flat, stable surface and secure it with wheel chocks.
Raise the front of the vehicle using a floor jack and support it with jack stands.

2. Visual Inspection

Inspect each tie rod for visible signs of wear or damage, including the outer and inner tie rod ends.
Look for cracks, rust, or any abnormal wear patterns.

3. Manual Shake Test

Grasp the tie rod and shake it side to side.
If there is excessive play, mark the location and proceed to replace the tie rod.

4. Replacement (if necessary)

1. Remove the Old Tie Rod

Use a socket set to remove the nut securing the outer tie rod end to the steering knuckle.
If necessary, use a tie rod puller to separate the tie rod from the knuckle.
Remove the inner tie rod by using a wrench to unscrew it from the steering rack.

2. Install the New Tie Rod

Apply anti-seize lubricant to the threads of the new inner tie rod.
Install the new tie rod into the steering rack and torque to manufacturer specifications (usually around 35-45 lb-ft).
Connect the outer tie rod end to the steering knuckle and secure it with the nut, torquing to specifications (typically 40-50 lb-ft).

5. Alignment Check

After installation, it is advisable to get a wheel alignment performed to ensure proper handling and tire wear.
