What This Product Does

An engine mount secures the power unit to the supporting structure while controlling movement caused by engine torque, acceleration and changes in load. Its resilient damping element also helps isolate drivetrain vibration from the body, supporting correct engine alignment and reducing stress on nearby exhaust components, hoses, wiring and connections.

Functions

• Supports and locates the 4.8L V8 engine within the chassis
• Controls drivetrain movement during acceleration and deceleration
• Helps isolate engine vibration from the passenger compartment
• Maintains alignment between the engine and associated drivetrain components
• Reduces movement that may place strain on exhaust parts, hoses and wiring

Technical Details

• Application: Porsche Cayenne 92A, also identified as the 958 generation
• Engine capacity: 4.8L V8
• Associated model and engine identifiers in the parts diagram: 4802, 4852, CFTB, CFT, CYXA and CYX

Symptoms of Fault

• Increased vibration through the cabin, particularly when idling
• Thumping or clunking when engaging gear or changing throttle position
• Excessive engine movement during inspection under load
• Drivetrain shunt during acceleration or deceleration
• Knocking from the exhaust or adjacent brackets
• Visible sagging, cracking or deterioration of the existing mount
• A less precise or notchy sensation when shifting gear

Why Replacement Matters

Heat cycling, vibration, engine torque and age can gradually reduce the mount's ability to support and damp the drivetrain. Replacing a worn Porsche 958 Cayenne 4.8L engine mount can restore more controlled engine positioning and address vibration or knocking associated with excess movement. The left and right mounts are side-specific, so the vehicle and installation position should be checked against the part number before fitting. Inspecting both engine mounts and the related transmission mounting at the same time can help identify additional wear within the mounting system.

FAQs

• Are the mounts interchangeable? No. The left and right positions have separate part numbers.
• Will replacing a worn mount reduce vibration? It may correct vibration caused by a degraded mount, but other drivetrain or engine faults should also be ruled out.
• Should both mounts be inspected? Yes. The opposite engine mount and supporting drivetrain mounts should be examined for deterioration or excessive movement.
