The Seal Ring, steering knuckle (2.50015) seals the stub axle to retain lubrication and block contamination. Replacing a worn ring with Porza quality restores safe and reliable wheel-end protection.
A seal ring for a steering knuckle is a sealing component used to protect the knuckle’s joints and bearings. Its function is to prevent dirt, moisture, and contaminants from entering while helping retain lubrication for smooth steering operation.
Key specifications include inner and outer diameter, thickness, material (such as rubber or elastomer), durability, and compatibility with the steering system. It must withstand mechanical stress and environmental exposure.
Replacement is necessary when the seal is worn, cracked, or damaged. Common symptoms include contamination of the joint, increased wear, or reduced steering performance.
Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.
Porza provides high-quality steering and suspension components with fast delivery across Europe and options for online ordering or in-store pickup.
