Product Information
Product Information

The part reference 955 349 337 00 is a rubber mounting / support mount for the front-axle final drive / differential, isolating and supporting the front differential (front drive unit) relative to the chassis. There are 3 of the same on each car, this is a SET OF 3 with bolts & nuts

Its purpose is to absorb and damp vibrations, reduce noise transmitted to the chassis, and accommodate slight relative motion between the drivetrain and the vehicle body 

Fits:
  • Porsche 955 Cayenne 3.2L V6 2003-06
  • Porsche 955 Cayenne S 4.5L V8 2003-06
  • Porsche 955 Cayenne Turbo 4.5L 2003-06
  • Porsche 955 Cayenne Turbo S 4.5L 2006>>
  • Porsche 957 Cayenne 3.0L Diesel 2007-10
  • Porsche 957 Cayenne 3.6L 2007-10
  • Porsche 957 Cayenne S/GTS 4.8L 2007-10   (excluding Turbo)


Why these should be replaced / when to suspect failure

  • This part is not “optional” — it is essential for maintaining proper alignment, damping, and support of the front differential. But because of its rubber nature and exposure, it is a known wear/failure point. Below are reasons and symptoms for replacement:
  • Rubber degradation (cracking, hardening, tearing). Over time, the rubber can become brittle, crack, or split from repeated stress cycles, heat, chemical exposure (oil, road salt, etc.). This reduces its damping ability.
  • Delamination / bond failure. The bonding between the rubber and the metal interfaces can fail, leading to slippage or separation under load.
  • Excessive deformation / sagging. As the rubber softens or wears, the mount may deform under load, causing misalignment or increased movement under torque.
  • Fatigue / wear from repeated cycles. Especially under harsh driving conditions (off-road, heavy loads, aggressive acceleration/shifting), the stress cycles on the mount accelerate wear. Some aftermarket writeups claim that the factory rubber design is prone to “premature Drive Shaft Support failure” because of constant stress on the rubber.
  • Heat / ozone / environmental damage. Exposure to high temperatures, undercarriage heat, moisture, road debris, and ozone accelerates rubber aging.
  • Load shift or impact damage. If the vehicle strikes a pothole or the differential experiences shock loads, the mount may crack or tear.

Why Replacement Matters

An aged or damaged Porsche Cayenne transmission mount may no longer control movement or isolate vibration effectively. Replacing a worn mount can restore correct gearbox support and prevent unnecessary movement from placing additional stress on nearby brackets, fixings and driveline parts. Other mounts and supporting components should be inspected during the repair, as wear elsewhere can produce similar symptoms.

FAQs

  • Can a worn mount feel like a gearbox fault?
    Yes. Movement, vibration and clunking from a deteriorated mount can make an otherwise serviceable gearbox feel rough. The drivetrain should be inspected before internal transmission repairs are considered.
  • Will this mount fit every 955, 957 or 958 Cayenne?
    No. Suitability depends on the engine, model year and transmission PR code. Cross-check part number 95537505720 and the vehicle specification.
  • Should related mounts be inspected?
    Yes. Checking the remaining engine and transmission mounts can help identify uneven support or additional deterioration.
  • Does a new mount repair gear crunching?
    Not normally. Gear crunching is more commonly associated with clutch, selector or internal transmission wear, although replacing a failed mount may improve general drivetrain stability.

Common failure modes / deterioration

Rubber degradation (cracking, hardening, tearing)

Over time, the rubber can become brittle, crack, or split from repeated stress cycles, heat, chemical exposure (oil, road salt, etc.). This reduces its damping ability.

Delamination / bond failure

The bonding between the rubber and the metal interfaces can fail, leading to slippage or separation under load.

Excessive deformation / sagging

As the rubber softens or wears, the mount may deform under load, causing misalignment or increased movement under torque.

Fatigue / wear from repeated cycles

Especially under harsh driving conditions (off-road, heavy loads, aggressive acceleration/shifting), the stress cycles on the mount accelerate wear. Some aftermarket writeups claim that the factory rubber design is prone to “premature Drive Shaft Support failure” because of constant stress on the rubber.

Heat / ozone / environmental damage

Exposure to high temperatures, undercarriage heat, moisture, road debris, and ozone accelerates rubber aging.

Load shift or impact damage

If the vehicle strikes a pothole or the differential experiences shock loads, the mount may crack or tear.

About Gearbox Mounts

Porsche Gearbox Mounts | Stability, Precision & Reduced Drivetrain Vibration

Gearbox mounts (also known as transmission mounts) are essential components that secure your Porsche’s gearbox to the chassis while isolating vibration and absorbing torque movement. These mounts play a crucial role in maintaining drivetrain alignment, smooth shifting, and overall driving comfort.

At Design911, we supply high-quality gearbox mounts and transmission mounting kits engineered to meet or exceed original performance specifications. Constructed from advanced rubber, polyurethane, or hydraulic materials, each mount provides the perfect balance of flexibility and strength — ensuring your Porsche maintains stable, refined performance under both road and track conditions.

Whether you’re restoring a classic Porsche or maintaining a modern performance model, our gearbox mounts deliver long-lasting stability, improved handling, and reduced drivetrain noise and harshness.

What Do Gearbox Mounts Do?

Gearbox mounts act as the vital connection between your Porsche’s transmission system and chassis, absorbing torque and vibration while maintaining alignment under load.

Core Functions:

  • Secure the gearbox in place under acceleration, braking, and cornering.
  • Absorb vibration and noise from the drivetrain.
  • Maintain correct driveshaft and linkage alignment.
  • Prevent excess movement that can stress surrounding components.

Without properly functioning gearbox mounts, excessive drivetrain movement can lead to harsh shifting, vibration, and even damage to exhaust, linkage, or driveshaft components.

Why Do Gearbox Mounts Fail or Wear Out?

Over time, gearbox mounts degrade due to exposure to engine heat, torque stress, and environmental factors such as oil contamination or moisture.

Common Causes of Failure Include:

  • Rubber deterioration or cracking from heat and age.
  • Hydraulic fluid leakage in fluid-filled mounts.
  • Metal fatigue in high-performance or heavy-load use.
  • Oil contamination softening rubber compounds.
  • Continuous torque stress from aggressive acceleration.

As mounts weaken, you may experience clunking noises, drivetrain vibration, gear lever movement, or difficulty shifting — all signs that your gearbox mounts need replacement.

Why Replace or Upgrade Your Gearbox Mounts?

Replacing worn gearbox mounts restores drivetrain stability, smoother shifting, and reduced vibration. Upgrading to reinforced or performance mounts enhances control and torque response, especially on tuned or track-driven Porsches.

Key Benefits:

  • Restores smooth, vibration-free gear changes.
  • Prevents drivetrain movement and component stress.
  • Improves handling precision and throttle response.
  • Reduces noise, vibration, and harshness (NVH).
  • Available in rubber, polyurethane, and performance-spec designs.
  • Ideal for maintenance, upgrades, or complete gearbox servicing.

Replacing mounts in pairs ensures balanced performance and consistent driveline alignment.

Highlights

  • Premium Porsche gearbox and transmission mounts.
  • Engineered for strength, durability, and vibration reduction.
  • Direct-fit replacements for Porsche 911, Cayman, Boxster, and others.
  • Reinforced designs for performance or track applications.
  • Reduces stress on transmission and drivetrain components.
  • Essential for smooth shifting, refinement, and drivetrain longevity.
