1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your MOOG ES323R Steering Tie Rod End. Designed for durability and performance, this component is crucial for your vehicle's steering system. Please read all instructions carefully before proceeding with installation or maintenance.
The MOOG ES323R is compatible with: 1964-1964 Chevrolet G10 Van; 1963-1982 Chevrolet Corvette.
2. Product Overview
2.1. Components
The MOOG ES323R Steering Tie Rod End consists of a threaded shaft, a ball joint encased in a protective boot, a castle nut, a cotter pin, and a grease fitting. These components work together to connect the steering rack to the steering knuckle, allowing for precise steering control.

2.2. Key Features
- Superior Materials: Backed by superior materials and rigorous testing for reliable performance.
- Problem Solver Gusher Bearing: Metal-to-metal design provides strength and allows grease to flow through bearing surface for reduced friction and long life.
- Strong and Durable: Ball studs are heat processed to match or exceed OE requirements to inhibit premature failure and improve fatigue strength.
- Restores Like-New Steering: Patented pressed-in cover plate seals out debris and minimizes looseness, reducing bearing wear and promoting longer life.
- Greaseable Socket: Inhibits corrosion and wear by allowing new lubricant to flush debris.
- Easy to Install: Precision tolerances for easy installation and steering alignment.
3. Installation Guide
Proper installation is critical for the longevity and performance of your tie rod end. Always refer to your vehicle's specific service manual for detailed torque specifications and procedures.
3.1. Pre-Installation Checklist
- Ensure the part is correct for your vehicle by verifying year, make, model, engine, and trim.
- Gather all necessary tools, including a torque wrench, tie rod end puller, and appropriate sockets/wrenches.
- Ensure the vehicle is safely supported on jack stands or a lift.
3.2. Installation Steps
- Prepare the Vehicle: Lift the vehicle and remove the wheel to access the tie rod end.
- Remove Old Component: Loosen the jam nut on the tie rod shaft. Use a tie rod end puller to separate the old tie rod end from the steering knuckle. Remove the old tie rod end.
- Measure and Align: Before installing the new tie rod end, measure the exposed thread length of the old tie rod end to ensure proper initial alignment. This will help maintain toe settings.
- Install New Tie Rod End: Thread the new MOOG ES323R onto the tie rod shaft. Ensure the stud is centered in its socket during installation. The steering linkage naturally wants to twist, and if the stud is not centered, it can stretch out the socket, leading to premature failure and looseness over time.
- Secure to Knuckle: Insert the stud into the steering knuckle. For vehicles with aluminum steering knuckles, exercise caution. Over-torquing a steel stud into an aluminum knuckle can stretch the knuckle, causing vibration and damaging the bearing inside the socket.
- Torque the Nut: Install the castle nut onto the stud and torque it to the vehicle manufacturer's specifications using a torque wrench. Do not rely on impact wrenches for final torque.
- Insert Cotter Pin: Secure the castle nut with the new cotter pin provided.
- Final Checks: Re-install the wheel and lower the vehicle. It is highly recommended to have a professional wheel alignment performed immediately after replacing tie rod ends to ensure correct steering geometry and tire wear.

4. Operating Principles
The tie rod end is a critical component of your vehicle's steering and suspension system. It acts as a pivot point, allowing the steering knuckle (and thus the wheel) to turn in response to steering wheel input. The ball-and-socket design accommodates the complex movements required for steering and suspension travel, ensuring smooth and responsive handling.
5. Maintenance
5.1. Lubrication
The MOOG ES323R features a greaseable socket. Regular lubrication with appropriate chassis grease is essential to flush out debris, inhibit corrosion, and reduce wear, thereby extending the life of the component. Consult your vehicle's service manual for recommended lubrication intervals.
5.2. Inspection
Periodically inspect the tie rod end for signs of wear, damage, or looseness. Check the protective boot for cracks or tears, which can allow contaminants to enter the ball joint. Any excessive play or unusual noises from the steering system should be investigated promptly by a qualified technician.
6. Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| Clunking or knocking noise from front suspension | Loose or worn tie rod end; stud not centered in socket during installation. | Inspect tie rod end for play. If new, ensure stud was centered and nut torqued correctly. Replace if worn. |
| Excessive vibration in steering wheel | Over-torqued nut stretching aluminum knuckle; worn tie rod end. | Check torque specifications. Inspect knuckle for damage. Replace tie rod end if worn. Perform wheel alignment. |
| Uneven tire wear | Incorrect wheel alignment; worn steering components. | Perform a professional wheel alignment. Inspect all steering and suspension components. |
| Loose or sloppy steering feel | Worn tie rod end or other steering components. | Inspect tie rod end and other steering components for play. Replace worn parts. |
