Information
Drive shaft sealing ring,
65 x 85 x 8. REAR OUTER SEALING RING
Shaft sealing ring, also commonly referred to as a drive shaft or outer seal, that sits around a rotating shaft or axle in the rear differential/axle assembly. Its primary function is to keep gear oil or differential lubricant contained while preventing contamination from entering the assembly.
Fits:
Porsche 911 (930) Turbo 1975 - 1989
Diagram ref no 11.
• Dimension: Manufactured to replicate the original Porsche part’s critical dimensions (65 × 85 × 8 mm)
• Position: Outer drive-shaft or axle tube interface, rear differential assembly
• Benefit: Accurate dimensions & material matching for proper sealing and long life
Over time, the original seal may harden, crack, or fail under heat, oil exposure and axle rotation, leading to oil leakage, differential lubricant loss or contamination ingress—potentially accelerating bearing or gear wear.
When to Replace:
• During rear axle or differential service, especially when removing the drive-shaft/cross-tube.
• If you observe lubricant leaking from around the outer axle or trailing arm area, or cleaned-up oil traces near the seal.
• As part of preventative maintenance when rebuilding suspensions or axles, especially in Turbo-Look or high-performance 911 models
Replacing with a new seal restores correct internal lubrication, prevents leakage and protects drivetrain components for the long term.
