Maserati Ghibli Quattroporte steering gear

The steering gear (steering rack) for the Maserati Ghibli (M157) and Quattroporte (M156) is a major component that often features cross-compatibility across these platforms. However, due to the critical nature of this part and the presence of different versions (Hydraulic vs. Electric, RWD vs. AWD), precise identification is essential for your inventory.

1. Key Compatibility Insights

• Platform Sharing: Many of these racks are interchangeable between the Ghibli (2014+) and the Quattroporte (2013+) because they share the same chassis architecture.

• Core Identification: Always confirm whether the unit is for RWD or AWD (Q4), as the mounting points and housing geometry can differ.

• Technology Shift: Be aware that Maserati transitioned from hydraulic power steering to electric power steering (EPS) in later production years (around 2018+). These systems are not interchangeable.

2. Common Part Numbers to Reference

When building your catalog, these are frequent OE numbers you will encounter. Always verify these against a specific VIN to ensure the customer receives the correct assembly:

• 670102931: Frequently cited as a common complete steering rack unit for various Ghibli/Quattroporte models.

• 06700039560 / 6700039560: A standard part number for earlier model years (2014–2017).

• 670106621: Commonly associated with newer (2018+) Electric Power Steering units.

3. Inventory & Sourcing Recommendations

• Core Deposits: Because steering racks are expensive to manufacture, almost all reputable suppliers charge a “core deposit” (often ranging from $500 to $2,000). As a dealer, this is a standard practice you should implement to encourage customers to return their damaged, rebuildable racks.

• Remanufactured vs. New: Given the price point of new OEM units, a high-quality “OE Remanufactured” rack is often the most popular choice for your customers. Ensure your supplier provides a warranty (typically 3 years/unlimited mileage) and that they perform load-testing on a simulator to ensure the unit doesn’t have internal dead zones.

• Inspection Checklist: If you are buying these as inventory, check for:

  • Dust Boot Integrity: Ripped boots are the primary cause of internal seal failure due to moisture and debris.

  • Thread Condition: Ensure the tie-rod mounting points are not cross-threaded or corroded.

  • Housing Damage: Any cracks or impact marks on the aluminum housing make the unit non-rebuildable.

4. Technical Documentation for Sales

Since you prioritize customer-centric service, your listings should clearly state:

1. Fitment Table: Explicitly list years and model variants (e.g., “Fits 2014–2016 Ghibli RWD”).

2. Core Requirement: Clearly define the core deposit amount and the procedure for the refund.

3. Included Items: Specify if the assembly includes inner tie rods or if they must be ordered separately.
