The Porsche Rear Differential Mounting Bush Kit is a genuine drivetrain mounting solution designed to securely support the rear differential assembly while minimising noise, vibration and harshness (NVH) transmitted to the vehicle chassis. Engineered to Porsche's exact specifications for fit, durability and performance, this kit restores the stability and refinement of the rear drivetrain system.

Comprising the primary differential mounting bushes, the kit provides a controlled yet flexible connection between the rear differential housing and the vehicle structure. Manufactured from high-quality bonded rubber and metal components, these bushes are designed to absorb drivetrain loads and vibrations while maintaining precise differential alignment during acceleration, braking and cornering.
What This Product Does:
- Secures the rear differential assembly to the chassis.
- Controls drivetrain and differential movement under load.
- Absorbs noise, vibration and harshness generated by the drivetrain.
- Maintains correct differential positioning and alignment.
- Reduces shock loads transferred through the vehicle structure.
- Improves ride comfort and driving refinement.
- Supports smooth and efficient power delivery to the wheels.
- Helps protect surrounding drivetrain and suspension components from excessive stress.
Symptoms Of Wear Or Failure:
- Clunking or knocking noises from the rear of the vehicle.
- Excessive differential movement during acceleration or deceleration.
- Drivetrain shunt when engaging drive or changing gear.
- Increased vibration felt through the cabin or floorpan.
- Thumping noises during take-off or load changes.
- Reduced drivetrain refinement.
- Rear-end instability under acceleration.
- Visible cracking, splitting or separation of the rubber bush material.
- Premature wear of driveshafts, mounts or associated drivetrain components.
Why Replacement Matters:
- Rear differential mounting bushes are subjected to constant torque loads, road impacts, vibration and environmental exposure. Over time, the rubber components can harden, crack, compress or separate from their metal housings, reducing their ability to absorb movement and vibration effectively.
- When the bushes deteriorate, the differential can move excessively within its mountings, creating unwanted noise, vibration and stress throughout the drivetrain. Left unchecked, this excessive movement can accelerate wear of driveshafts, mounting brackets, suspension components and the differential itself.
- Replacing worn differential mounting bushes restores proper drivetrain support, improves vehicle refinement and ensures precise differential alignment. A genuine Porsche bush kit provides factory-correct fitment, excellent vibration isolation and long-term durability, helping maintain the smooth performance, handling stability and driving comfort expected from your Porsche.
