FAQs
What are the dimensions of this seal?
The Corteco 12014825B has exact dimensions of 29.8mm inner diameter, 50mm outer diameter, and 10mm width.
Does this seal fit the passenger side as well as the driver side?
While it is often used for driver side or front differential applications, compatibility depends entirely on your specific vehicle drivetrain. Please check your service manual.
Should I apply sealant to the outside of the metal casing?
Typically, these seals are designed to be a press-fit. Using additional liquid sealant is usually not required unless specified by your vehicle's service manual.
How do I know if my differential seal is failing?
Common signs include puddles of gear oil under the vehicle near the wheels or transmission, or oil splatters visible on the inner CV boot area.
Is lubrication required before installation?
Yes, it is recommended to apply a thin film of clean gear oil to the inner rubber lip to ensure the seal operates smoothly during the first rotation.
Troubleshooting
Seal leaking immediately after installation
Verify the seal was seated perfectly square in the housing and check if the axle shaft surface had any deep scratches or debris.
Difficulty seating the seal into the housing
Use a dedicated seal driver tool rather than a screwdriver or mallet to apply even pressure around the outer diameter.

Setup, Compatibility & Care
Proper installation is vital for the functionality of this seal. Always use a seal driver of the correct diameter to ensure the seal enters the housing squarely; using a hammer or punch directly on the seal will cause deformation and immediate leaks. Ensure the shaft surface is free of nicks, rust, or debris, as any surface imperfection will tear the rubber lip of the new seal. Before installation, lightly lubricate the sealing lip with clean differential oil to prevent dry-start wear. Always cross-reference your vehicle's make, model, and transmission/differential code against the 29.8x50x10 specifications before beginning your repair.
