4. Installation Instructions
The following steps provide a general guide for replacing a tie rod end. Specific procedures may vary by vehicle make and model. Always consult your vehicle's service manual.
- Prepare the Vehicle:
Park the vehicle on a level surface, engage the parking brake, and block the rear wheels. Loosen the lug nuts on the wheel where the tie rod end will be replaced. Raise the front of the vehicle using a jack and secure it with jack stands. Remove the wheel.
- Mark Alignment:
Before removal, measure and record the exposed thread length on the old tie rod end. This measurement will help approximate the initial alignment for the new tie rod end. Alternatively, count the number of turns required to remove the old tie rod end from the tie rod shaft.
- Remove Old Tie Rod End:
Remove the cotter pin and castle nut securing the tie rod end to the steering knuckle. Use a tie rod end puller or a pickle fork to separate the tie rod end from the steering knuckle. Loosen the jam nut on the tie rod shaft, then unthread the old tie rod end from the shaft.

- Install New Tie Rod End:
Thread the new MOOG ES801215 tie rod end onto the tie rod shaft. Adjust it to the previously recorded measurement or number of turns. Ensure the jam nut is still loose. Insert the tapered stud of the new tie rod end into the steering knuckle. Install the castle nut and tighten it to the vehicle manufacturer's specified torque. Insert a new cotter pin through the castle nut and stud, bending the ends to secure it.
- Tighten Jam Nut:
Once the tie rod end is properly seated and secured, tighten the jam nut against the tie rod end to the manufacturer's specified torque. This prevents the tie rod end from rotating and changing the alignment.
- Final Steps:
Reinstall the wheel and tighten the lug nuts. Lower the vehicle to the ground and torque the lug nuts to specification. Immediately schedule a professional wheel alignment.
5. Usage and Function
The MOOG ES801215 Steering TIE Rod END is a critical component of your vehicle's steering system. It facilitates the transfer of steering input from the steering rack to the wheels, allowing for precise control and maneuverability. A properly functioning tie rod end ensures stable handling and prevents premature tire wear.
6. Maintenance
Regular inspection and maintenance can extend the life of your tie rod end and ensure safe vehicle operation.
- Visual Inspection: Periodically inspect the tie rod end for signs of wear, such as torn dust boots, excessive play, or corrosion. A torn boot can allow dirt and moisture to enter the ball joint, leading to premature failure.
- Lubrication: If your tie rod end is equipped with a grease fitting (zirc fitting), lubricate it with appropriate chassis grease at recommended service intervals, typically during oil changes or tire rotations. Use the provided funnel if needed for other lubrication tasks on your vehicle.
- Professional Check: Have your steering and suspension components inspected by a qualified technician during routine vehicle servicing.
7. Troubleshooting
If you experience any of the following symptoms, your tie rod end may require inspection or replacement:
| Symptom | Possible Cause | Action |
|---|---|---|
| Loose steering / Excessive play | Worn tie rod end ball joint | Inspect tie rod end for play; replace if worn. |
| Uneven tire wear | Misalignment due to worn tie rod end | Inspect and replace worn components; perform wheel alignment. |
| Clunking or popping noises from front suspension | Severely worn or damaged tie rod end | Immediately inspect and replace the tie rod end. |
| Steering wheel off-center | Incorrect tie rod end adjustment or wear | Perform wheel alignment after inspection/replacement. |
