Prekom torque tube bearings available for different Porsche models

Torque tube is a cylindrical, rigid structural element that connects the engine with the transmission. It is a specific part of the car used in some of the Porsche models, particularly those with a front-engine, rear-wheel-drive layout. This layout is most commonly associated with the Porsche 924, 944, 968, 928, 993, 964 and 911 (with 4-wheel drive configurations).

Torque tube has several important purposes in the vehicle’s design:

• Torque transfer – torque tube plays a crucial role in transferring the engine’s power to the transmission and ultimately to the wheels. It maintains a direct and rigid connection between the engine and the drivetrain components, improving power delivery and responsiveness.
• Stiffness and Handling – torque tube also adds structural rigidity to the chassis of the car. This rigidity helps improve the car’s handling characteristics and overall stability, particularly during high-speed driving and aggressive cornering.
• Weight Distribution – by placing the heavy engine at the front of the car and connecting it to the transmission via the torque tube, Porsche achieves a near-perfect weight distribution between the front and rear axles. This balance contributes to the car’s excellent traction and handling characteristics.
• Noise and Vibration Isolation – torque tube can also serve as an isolator since it can isolate engine noise and vibrations from the passenger compartment, providing a more comfortable and refined driving experience.

Critical part of a torque tube assembly are torque tube bearings. When torque tube bearings fail, this can lead to various symptoms and issues. Some signs that may indicate torque tube bearing failure are:

• Unusual Noise – most common signs of torque tube bearing failure is unusual noises coming from the vehicle. Grinding, whining or rumbling sounds can occur when the bearings are worn or damaged.
• Vibration – when torque tube bearings are failing, you may experience increased vibrations, especially during acceleration or at specific speeds. Due to bearing wear imbalanced rotation of the drivetrain components may occure.
• Difficulty Shifting Gears – failing torque tube bearings can affect the transmission’s operation. It becomes difficult to shift gears smoothly, or grinding noises can be heared when attempting to shift.
• Reduced Performance – as the bearings deteriorate, they can create additional friction and resistance in the drivetrain, leading to reduced engine performance and acceleration.
• Fluid Leaks – In some cases, failing torque tube bearings can cause leaks of transmission or differential fluid.

It’s essential to have your vehicle inspected if you experience any of the above mentioned symptoms or suspect that your torque tube bearings may be failing. Ignoring torque tube bearing issues can lead to more expensive and extensive damage to your car components. Diagnosing and repairing torque tube bearings as soon as problems occure is crucial to maintain the performance and safety of your vehicle.

Prekom torque tube bearings available for different Porsche models

Porsche does not provide the torque tube bearings and you can maintain the torque tube bearings failure only when buying a complete new torque tube.

We, at Prekom, had numerous customers, asking us to solve their problem with the torque tube bearing failure, so we decided to develop, design and manufacture some of the most common bearings and rubber carriers for torque tubes. We now offer torque tube bearings for 944, 928, 964 and 993 Porsche torque tubes.
