Extended Product Information

FAQs

What is the primary function of this differential shaft seal?

Its primary function is to prevent transmission fluid from leaking out of the differential housing and to keep dirt and moisture from entering the transmission.

How do I know if I need to replace my differential shaft seal?

Signs include visible fluid leaks around the transmission's axle seals, a low transmission fluid level, or a burning smell caused by fluid leaking onto hot exhaust components.

Can I use this seal on any transmission?

No, this seal has specific dimensions (74mm OD, 60mm ID) and is designed for certain manual and dual-clutch transmissions, particularly those with MQ350 codes found in VW, Audi, Skoda, Seat, and Ford vehicles. Always verify compatibility.

What does the 'dust cover with a lip' do?

This feature provides an additional barrier against environmental contaminants like dust, dirt, and water from reaching the primary sealing lip, helping to extend the seal's lifespan.

Is this an OEM part?

This is an original Elring part, known for its expertise in automotive sealing solutions. While Elring is a reputable aftermarket supplier, it's important to verify if it matches the original equipment specifications for your vehicle.

What tools are typically needed for installation?

Professional installation typically requires tools such as a lift, transmission jack, various wrenches and sockets, seal pullers, and seal drivers to ensure the seal is pressed in correctly and without damage.

How long should this seal last?

With proper installation and normal operating conditions, a high-quality seal like this from Elring should last for many years and miles, often matching the lifespan of original equipment.

Troubleshooting

Seal leaks immediately after installation

The seal may have been installed incorrectly (e.g., crooked, damaged during installation) or the mating surface on the shaft/housing may be damaged. Re-inspect installation and surfaces.

Premature wear or failure of the seal

Check for excessive transmission fluid temperature, contamination in the fluid, or improper shaft runout. Ensure correct fluid type and level are maintained.

Difficulty installing the seal

Ensure the correct seal is being used for the application and that the seal housing is clean. Use appropriate seal-driving tools to install the seal squarely.

Noise or vibration from the transmission after seal replacement

This is unlikely to be directly caused by the seal itself unless it was damaged during installation, causing misalignment. Double-check all related components that were disturbed during the seal replacement.

Setup, Compatibility & Care

Setup:

Installation of this differential shaft seal should only be performed by a qualified mechanic or experienced DIYer with the necessary tools. The process typically involves:

  1. Safely lifting and supporting the vehicle.
  2. Draining the transmission fluid.
  3. Accessing the differential area (may require removing driveshafts or other components).
  4. Carefully removing the old seal.
  5. Cleaning the seal housing area.
  6. Lubricating the new seal and the shaft.
  7. Pressing the new seal in squarely and fully, ensuring it is seated correctly.
  8. Reassembling all components.
  9. Refilling the transmission with the correct type and amount of fluid.

Compatibility:

This seal is designed for specific manual and dual-clutch transmissions, often found in VW, Audi, Skoda, Seat, and Ford vehicles. Key compatibility points include:

  • Outer Diameter: 74mm
  • Inner Diameter: 60mm
  • Transmission Codes: Such as MQ350
  • Installation Location: Front axle

Always verify your vehicle's make, model, year, and specific transmission code against the manufacturer's compatibility information or consult a professional before purchasing.

Care:

Once installed, this seal requires no specific user maintenance. Its function is passive, but its longevity depends on correct installation and ensuring the transmission operates within normal parameters (temperature, fluid level). Regular transmission fluid checks and changes as per your vehicle manufacturer's schedule will help protect the seal and the transmission.
