Lemförder 38923 01 - Inner Tie Rod

Lemförder 38923 01 – Inner Tie Rod

The Inner Tie Rod (Lemförder 38923 01) is a high‑performance steering component designed to provide precise wheel alignment and robust load handling in both passenger cars and light commercial vehicles. It serves as the critical link between the steering rack and the wheel hub, translating driver input into accurate tire movement while withstanding lateral forces during cornering.

Key Functional Characteristics

• Load Capacity: Engineered to handle high torsional loads typical of modern front‑wheel drive platforms. The rod’s cross‑section and material composition allow it to maintain structural integrity under repeated stress cycles.
• Precision Alignment: The inner tie rod is manufactured with tight dimensional tolerances, ensuring minimal play between the steering rack and wheel hub. This precision translates into reduced steering effort and improved vehicle stability.
• Durability: Constructed from high‑strength alloy steel (often 42CrMo4 or equivalent), the component resists fatigue and corrosion when properly treated with protective coatings such as zinc plating or powder coating.
• Compatibility: Designed to fit a wide range of vehicle models, including Mazda CX‑5 (2011‑2017), various front‑wheel drive cars, and light trucks. The part number is often referenced in OEM catalogs under titles like “Axial Ball, Track Rod” or “Rotule Axiale.”
• Ease of Installation: Features a standard M14x1.5 thread on the inner end for secure attachment to the steering rack, while the outer end mates with the wheel hub assembly via a universal joint or ball‑joint interface.

Material and Finish

The rod is fabricated from high‑strength alloy steel (42CrMo4), known for its excellent toughness and resistance to fatigue. After forging, the component undergoes heat treatment—typically austenitizing followed by quenching and tempering—to achieve the desired hardness profile.

To protect against environmental factors such as road salt, moisture, and temperature fluctuations, the inner tie rod is finished with:

• Zinc Plating – Provides sacrificial protection against corrosion.
• Powder Coating (optional) – Adds an additional layer of durability and aesthetic appeal.

Installation Procedure

1. Preparation: Remove the existing tie rod by loosening the wheel hub bolts, then detach the steering rack connection. Ensure all components are clean to avoid contamination of threads.
2. Thread Engagement: Align the M14x1.5 thread on the inner end with the steering rack’s corresponding socket. Apply a suitable thread‑locking compound to prevent loosening during operation.
3. Torque Specification: Tighten the connection to the manufacturer’s recommended torque (typically 70–90 Nm, depending on vehicle specifications). Use a calibrated torque wrench for accuracy.
4. Alignment Check: After installation, perform a wheel alignment test. Verify that the steering geometry matches OEM parameters: camber, caster, and toe settings should be within specified tolerances.
5. Final Inspection: Inspect for any play or abnormal noise during steering input. A properly installed inner tie rod will exhibit smooth operation with no rattling or binding.

Maintenance Tips

• Regular Inspection: Check the tie rod ends and universal joint for wear, especially after long drives on rough roads. Look for signs of corrosion or metal fatigue.
• Lubrication: Apply a high‑quality grease to the ball‑joint interface during installation. Reapply as needed if the vehicle operates in harsh conditions.
• Replacement Interval: While the inner tie rod is designed for longevity, it should be replaced if any of the following occur: visible cracking, excessive play, or loss of steering responsiveness.

Applications Across Vehicle Models

The Lemförder 38923 01 is widely recognized in automotive repair and aftermarket circles. It is commonly referenced under various language translations such as:

• Italian: “Snodo assiale” or “Articulation axial, barra di accoppiamento.”
• Spanish: “Rótula axial de dirección” or “Barra de conexión M14x1.5 304.”
• Polish: “Połączenie osiowe, drążek kierowniczy poprzeczny.”
• German: “Axialgelenk, Spurstange Vorderachse beidseitig innen.”

These translations reflect the component’s universal role in steering systems across multiple markets. Whether you’re servicing a Mazda CX‑5, a light truck, or any front‑wheel drive vehicle that requires an inner tie rod, the Lemförder 38923 01 delivers consistent performance.
