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

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.

OEMatch Front Differential — Fit, Function, Confidence
OEMatch front differential components for Porsche all-wheel drive models help you look after traction, refinement and driveline feel without compromising on Porsche-specific fit or application. Many owners search for genuine or OEM front differential parts; these are direct-fit alternatives designed to match the original form, fit and function.
- Front differential housings and internals for Porsche driveline systems
- Associated seals, bearings and hardware for correct operation
- Solutions suitable for routine maintenance, repair and refurbishment
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original front differential. OE (Original Equipment) refers to parts matching original specifications for the front differential and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM front differentials engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Understanding how these relate helps you choose suitable replacements when maintaining or refurbishing your Porsche’s driveline.
- Helps maintain consistent power delivery to the front wheels
- Supports stable, predictable handling in a variety of conditions
- Can reduce unwanted noise or harshness from the front driveline
- Assists in protecting related components by restoring correct operation
- Wear to gears, bearings or shafts from age, mileage or heavy use
- Lubrication issues, such as contaminated or degraded differential oil
- Seal deterioration leading to leaks and potential internal damage
- Previous repairs carried out with incorrect or mismatched parts
Keeping the front differential in good condition is important for preserving how your Porsche drives and feels. Replacing worn or noisy components can help restore smoothness, reduce driveline disturbances and support traction and control in everyday driving. When parts reach the end of their service life, installing suitable OEMatch items helps maintain confidence in the car on motorways, B-roads and in poor weather.
- Made to original-spec dimensions for consistent performance in Porsche applications
- Compatible with factory driveline layouts and ancillary systems
- Helps extend the useful life of other driveline parts by restoring correct load paths
- Supports long-term enjoyment and day-to-day usability of Porsche vehicles
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
