Bentley Bentayga Front Lower Control Arms 4M0407156C 4M0407155C

Genuine Bentley Bentayga front lower control arms, identified by OEM part numbers 4M0407156C and 4M0407155C. These suspension components form part of the Bentayga’s front lower suspension assembly and are designed to connect the wheel hub/suspension assembly to the vehicle chassis while allowing controlled suspension movement.

Current parts catalogues identify 4M0407155C with the Bentley Bentayga front lower control-arm application, including 2017–2020 vehicles. Bentley Bentayga suspension catalogues also show separate front lower control-arm assemblies and multiple control-arm positions depending on suspension configuration.

Product Specifications

Bentley Bentayga Front Lower Control Arms

The 4M0407155C / 4M0407156C references are associated with the Bentley Bentayga front suspension. The Bentayga uses a multi-link front suspension arrangement with separate control arms serving different positions.

A current OEM parts listing identifies 4M0407155C as a front-left lower control arm for 2017–2020 Bentayga applications.

Other Bentayga suspension catalogues list several distinct front control-arm positions, including upper forward, upper rearward and lower assemblies, making accurate part-number matching particularly important.

OEM Part Numbers

The main references for this listing are:

• 4M0407156C
• 4M0407155C

These numbers may also appear in formatted VAG/OEM notation as:

• 4M0 407 156 C
• 4M0 407 155 C

Always compare the complete suffix, not just the base 4M040715x number, because suspension components can have different revisions and applications.

Suspension Function

The front lower control arm is a key component of the Bentayga’s suspension system. It helps maintain the intended position and movement of the wheel assembly relative to the vehicle body while the suspension travels over different road surfaces.

A worn or damaged control arm can be associated with symptoms such as:

• Front-end knocking or clunking
• Excessive suspension movement
• Uneven tyre wear
• Steering instability
• Suspension vibration
• Damaged or deteriorated bushings

Diagnosis should be performed by a qualified technician before replacing suspension components.

Bentley Bentayga Compatibility

The 4M0407155C reference is documented for Bentley Bentayga applications, including model years from 2017 onward in current parts listings.

Bentayga suspension catalogues show applications beginning with the 4V1 Bentayga platform from 2015 onward, with different control-arm references depending on position and revision.

Because the Bentayga has multiple front control arms per side, buyers should verify whether the required component is the forward or rearward lower arm before ordering.

Replacement & Repair Applications

These front control arms are suitable for applications such as:

• Bentley Bentayga suspension repair
• Front-end suspension restoration
• Replacement of damaged control arms
• Replacement of worn suspension components
• Accident-damaged vehicle repair
• OEM suspension restoration
• Bentley specialist workshop repairs
• Suspension refurbishment

When replacing a control arm, the associated bushings, ball joints, fasteners and mounting points should also be inspected.

Condition

The actual condition should be confirmed from the individual parts supplied.

For used control arms, inspect carefully for:

• Bent arms
• Impact damage
• Cracks
• Corrosion
• Damaged bushings
• Worn mounting points
• Damaged ball-joint connections
• Previous repairs or modifications

A used suspension component should not be installed if there is evidence of structural deformation or damage.

Installation

Installation should be performed by a qualified technician familiar with Bentley and Volkswagen Group suspension systems.

Before installation, compare the replacement component with the original for:

• Complete OEM part number
• Shape and dimensions
• Mounting points
• Bushing locations
• Ball-joint connection
• Forward/rearward position
• Left/right orientation

After installation, the vehicle’s suspension geometry should be checked and a wheel alignment performed where required.

Buyer Verification

Before purchasing 4M0407156C / 4M0407155C, verify:

• Bentley Bentayga VIN
• Model year
• Engine/specification
• Suspension configuration
• Front left or front right position
• Forward or rearward control-arm position
• Existing OEM part number
• Physical shape of the original component

This verification is particularly important because current Bentayga catalogues identify multiple different front control-arm assemblies.
