Information
Drive shaft sealing ring, 58 x 81.2 x 5. REAR INNER SEALING RING
This seal fits around the rotating shaft or axle interface (typically within the rear wheel hub or drive-axle assembly) to keep lubricant contained and prevent dirt, moisture, and debris from entering. Its exact fit and high-quality materials ensure optimal lubrication, minimize wear, and extend the life of surrounding bearings and gears.
Fits:
Porsche 911 (930) Turbo 1975 - 1989
Diagram ref no 12.
• Dimension: Designed to replace the factory shaft or wheel hub seal (measuring 58 × 81.2 × 5 mm)
• Position: Rear wheel hub / drive-shaft bearing interface
• Benefit: Superior fit and sealing durability to maintain lubrication and protect drivetrain bearings and gears.
With time, heat, constant rotation, and oil exposure can cause the seal material to harden or crack. Once compromised, it allows lubricant to leak and contaminants to enter, leading to excessive bearing or gear wear and potential drivetrain failure.
When to Replace:
• During rear axle or differential servicing, or when removing the drive shaft or hub.
• If you notice oil or grease leaks around the axle, hub, or trailing arm area.
• As part of preventive maintenance on high-mileage or performance-driven Porsche models.
Replacing restores proper fit, material integrity, and sealing performance - protecting your drivetrain and extending component life.
