Maserati Ghibli Quattroporte MC20 Inner Tie Rod Axial Joint 673008100

Premium Inner Tie Rod / Axial Joint for Maserati – Part 673008100

Restore precise steering response with a replacement inner tie rod axial joint designed around Maserati part number 673008100. This steering link connects the steering rack to the outer tie-rod end and transfers steering input directly to the road wheel, making it a critical part of accurate tracking, stable alignment and predictable steering feel.

Materials & Construction

The assembly is built around a high-strength machined steel shaft with precision-cut threads and a hardened articulated inner joint. The joint housing is engineered to tolerate repeated steering loads while maintaining controlled movement through the suspension and steering range. The combination of rigid steel construction, accurately formed threads and a tightly fitted joint interface gives the component the solid feel required in a high-performance luxury steering system.

What It Does

The inner tie rod transmits movement from the steering rack to the outer tie rod and steering knuckle. A worn axial joint can contribute to steering play, vague on-centre feel, unstable tracking, uneven tyre wear and difficulty maintaining wheel alignment. Replacing the worn component helps restore direct steering response and keeps front-wheel toe adjustment within the correct working range.

Fitment & Reference

Reference number: 673008100. This part number is used across selected Maserati Ghibli, Quattroporte M156 and MC20 applications. Match the existing part number and steering configuration before installation.

How to Replace

1. Raise and safely support the vehicle, then remove the front wheel.
2. Mark or measure the existing tie-rod position to provide a useful starting point for reassembly.
3. Disconnect the outer tie-rod end from the steering knuckle and remove it from the inner rod.
4. Release the steering-rack boot and remove the original inner tie rod using the correct inner tie-rod tool.
5. Install the replacement axial joint to the specified tightening procedure, refit the rack boot and reinstall the outer tie rod.
6. Carry out a professional wheel alignment after installation.

Why Replace It?

A fresh axial joint improves mechanical connection between the steering rack and wheel assembly, supports consistent alignment and helps eliminate unwanted play caused by a worn inner joint.
