- Cold-drawn steel garter spring: The garter spring is made from cold-drawn steel wire, designed for strong fluid retention.
- Rigid metal case: The body is formed from deep-drawn sheet steel, creating a rigid, stress-resistant metal case.
- Tested for correct fit: Built with a tested design and high-quality materials for correct fit.
- Dirt and water protection: Designed to guard the seal area against dirt and water.
SKF has been developing seals since it introduced the first integrated shaft seal in 1928, and it has kept refining seal designs and bonding techniques since then. Its seals are built to specific designs with premium materials chosen to suit both the application and its operating environment, with the aim of keeping lubricants in and contaminants out.
The seal body stays stationary where the rear output shaft exits the transfer case, while its lip contacts the rotating shaft surface. Signs this part may need replacing include fluid seeping or dripping at the rear of the transfer case, wet residue near the driveshaft connection, or a transfer case fluid level that keeps dropping. Confirm the source of the leak before replacing. If a worn rear output seal is the cause, this seal replaces it.
