Engineered for precise fitment and long-term durability, this kit provides a full solution for worn or degraded front subframe mounting components.

What Front Subframe Mounts Do

The front subframe supports critical vehicle systems including:

• Front suspension components
• Steering rack assembly
• Engine mounting points (in certain configurations)
• Front drivetrain components

The subframe is secured to the chassis using rubber or bonded mounts designed to isolate vibration while maintaining structural alignment.

Front subframe mounts are responsible for:

• Securing the front axle assembly to the chassis
• Maintaining correct suspension geometry
• Supporting accurate steering response
• Reducing road vibration and harshness
• Stabilising braking and cornering loads

The mounting bolts apply the required clamping force to ensure the subframe remains securely positioned under heavy loads.

Why Front Subframe Mounts Fail

Over time, front subframe mounts are subjected to:

• Continuous suspension movement
• Steering input stress
• Engine and drivetrain torque
• Road impact and vibration
• Heat cycles and environmental exposure
• Rubber degradation due to age

As the mounts wear or crack, they lose their ability to properly isolate movement and maintain alignment.

Common signs of worn front subframe mounts include:

• Clunking or knocking from the front end
• Steering instability or wandering
• Vibration felt through the steering wheel
• Uneven tyre wear
• Poor front-end alignment
• Increased cabin noise

Mounting bolts may also stretch or corrode over time. Reusing old bolts can compromise clamping force and structural integrity.

Why You May Need a Complete Front Subframe Mount Kit

Replacing all four mounts at the same time ensures balanced support across the entire front chassis assembly. Installing new mounting bolts guarantees correct torque specification and safe installation.

This kit is ideal for:

• High mileage Porsche Cayenne models
• Vehicles with front-end knocking noises
• Steering or alignment issues
• Subframe removal during suspension or steering rack service
• Chassis restoration projects
• Preventative maintenance on ageing 955 / 957 / 958 Cayenne models

Replacing worn front subframe mounts restores factory handling characteristics and improves overall driving confidence.
