    Shaft Seal, differential

    The Shaft Seal, differential (01031731B) prevents differential oil leaks and protects internal gears from wear. Replacing a worn seal restores proper lubrication and ensures reliable axle performance. Use Porza’s smart search to find the correct seal.

    FAQ

    A shaft seal for a differential is a sealing component installed where the drive shafts or input shaft enter or exit the differential housing. Its function is to prevent gear oil leakage while protecting the internal components from dirt, moisture, and contaminants.

    Key specifications include inner and outer diameter, thickness, material (such as NBR, FKM, or PTFE), temperature resistance, pressure capability, and compatibility with the differential. It must withstand rotation, load, and exposure to gear oil.

    Replacement is necessary when the seal is worn, hardened, cracked, or leaking. Common symptoms include gear oil leaks near the differential, unusual noise due to reduced lubrication, or contamination inside the unit.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality drivetrain and sealing components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
