Required Quantity
Two support struts are required in the front cross-member/wishbone assembly for the listed applications.

What Is This Part?
This is a structural support strut, also described as a cross support, within the front suspension cross-member assembly. It works alongside the cross-member, suspension arms, wishbones and associated fixings to maintain the supporting arrangement. Its role is to brace the structure rather than provide springing or damping. When repairing this area, the condition of the strut and its attachment points should be assessed together with the surrounding components.

What Does This Part Do?

• Braces the cross-member: Supports the structural arrangement of the front suspension assembly.
• Connects supporting elements: Works through its attachments as part of the framework around the cross-member and wishbones.
• Maintains the intended support arrangement: Replaces a damaged strut within the existing mounting structure.

Why Replace This Part?
Replacement may be needed if inspection finds bending, cracking, significant corrosion or damage around the attachment points. These defects can affect how the strut seats and supports the cross-member structure. Impact damage or deterioration discovered during suspension repairs should therefore be assessed before the assembly is refitted.

Inspect the neighbouring arms, wishbones, bushes, joints, plates and fixings at the same time. A new support strut will not correct damage elsewhere in the assembly, and loose or deteriorated hardware needs separate attention. Assess wheel-alignment requirements whenever the repair disturbs suspension mounting positions.

When to Replace This Part?

• Visible distortion: The support is bent or no longer seats correctly at its attachment points.
• Cracks or corrosion: Inspection reveals deterioration affecting the strut or the material around its fixings.
• Damaged attachments: Mounting areas are worn, distorted or unable to hold the support securely.
• Following an impact: Check the support and surrounding structure for damage before deciding which parts require renewal.
• Persistent suspension symptoms: Knocks, altered tracking or irregular tyre wear warrant inspection of the complete assembly; they do not identify this strut as the cause.
• During removal and refitting: Check both supports, their seating surfaces and attachment hardware while access is available.

Where Is This Part Fitted?
Location: Within the front suspension cross-member/wishbone structure, attached at the support strut mounting points around the cross-member assembly.
