3. Installation Guidelines
Installation of steering and suspension components requires specialized tools and knowledge. It is highly recommended that this component be installed by a qualified automotive technician.
3.1. Pre-Installation Checks
- Ensure the vehicle is safely supported on jack stands or a lift.
- Confirm the new MOOG EV800648 tie rod end matches the removed component.
- Inspect surrounding components (e.g., steering rack, outer tie rod end, boots) for wear or damage.
3.2. General Installation Steps (Consult a Service Manual for Specifics)
- Loosen the jam nut on the outer tie rod end.
- Carefully count and record the number of turns required to remove the outer tie rod end from the inner tie rod end. This helps in setting initial alignment.
- Remove the boot clamps and slide the steering rack boot off.
- Using an appropriate inner tie rod removal tool, loosen and remove the old inner tie rod end.
- Thread the new MOOG EV800648 inner tie rod end onto the steering rack. Utilize the wrench flats for proper tightening. The pre-applied thread locker will secure the connection.
- Reinstall the steering rack boot and secure it with new clamps.
- Thread the outer tie rod end back onto the new inner tie rod end, matching the recorded number of turns.
- Tighten the jam nut.
3.3. Post-Installation
After installation, a professional wheel alignment is mandatory to ensure correct steering geometry and prevent premature tire wear. Failure to perform an alignment can lead to unsafe driving conditions.

4. Function and Performance
The inner tie rod end is a crucial link in your vehicle's steering system. It translates the rotational motion of the steering rack into linear motion, which then moves the outer tie rod end and ultimately the steering knuckle, allowing the wheels to turn. A properly functioning tie rod end ensures precise steering response and vehicle stability.
4.1. Signs of Wear or Failure
Worn or failing tie rod ends can compromise steering control and vehicle safety. Be aware of the following symptoms:
- Uneven Tire Wear: Irregular wear patterns on tires, particularly on the inner or outer edges.
- Vehicle Pulling: The vehicle drifts or pulls to one side, requiring constant steering correction.
- Steering Wheel Vibration: A noticeable vibration or looseness felt through the steering wheel, especially at higher speeds.
- Clunking Noises: Audible clunking or knocking sounds from the front suspension, particularly when turning or driving over bumps.
Symptom 1: Uneven Tire Wear
Symptom 2: Vehicle Pulling
Symptom 3: Steering Wheel Vibration
Symptom 4: Clunking Noise
5. Maintenance
Regular inspection of steering and suspension components is essential for vehicle safety and longevity. During routine vehicle maintenance, have a qualified technician inspect the tie rod ends for:
- Boot Integrity: Check for tears, cracks, or damage to the protective boot, which can allow contaminants to enter the joint.
- Play/Looseness: With the vehicle lifted, check for excessive play in the tie rod end by attempting to move the wheel horizontally.
- Corrosion: Inspect for signs of rust or corrosion on the component.
Address any signs of wear or damage promptly to maintain steering precision and prevent further component damage.
6. Troubleshooting
If you experience any of the symptoms listed in Section 4.1, or encounter issues during installation, consider the following:
- Installation Difficulty: If the tie rod end is difficult to install or tighten, ensure you are using the correct specialized tools (e.g., an inner tie rod removal tool with the appropriate hex size). Improper tools can damage the component or prevent proper tightening.
- Persistent Symptoms After Replacement: If symptoms persist after replacing the tie rod end, other steering or suspension components may also be worn or damaged. A comprehensive inspection by a professional is recommended.
- Alignment Issues: Always perform a professional wheel alignment after replacing tie rod ends to correct steering angles and prevent tire wear.
