OUTPUT AXLE SEAL- 3DU - 40 X 67 FOR TESLA MODEL 3/Y/S/X 1108557-00-A Rubber BLACK

The Output Axle Seal 1108557-00-A is a critical sealing component designed for Tesla Model 3, Model Y, Model S, and Model X vehicles. Engineered to prevent fluid leakage in the axle assembly, this 3DU-spec seal ensures optimal performance of the drivetrain by maintaining proper lubrication and blocking contaminants—protecting vital components from premature wear.

• Leak Prevention: The nitrile rubber construction forms a tight, flexible seal between the axle and housing, preventing expensive gear oil from leaking out. This maintains proper lubrication of axle components, reducing friction and extending their lifespan.
• Contaminant Blocking: Acts as a barrier against dirt, water, road salt, and debris—common culprits of axle wear and corrosion. By keeping these elements out, it safeguards bearings, gears, and shafts from damage.
• Durable Performance: The reinforced rubber (with embedded metal ring) resists cracking, shrinking, or hardening over time—even when exposed to high temperatures from the drivetrain or harsh chemicals like road de-icing salts.
• Universal Tesla Fit: Designed to match the axle specifications of Model 3, Y, S, and X, ensuring a precise, factory-like seal without modifications.

• Professional Installation Recommended: Requires axle removal to access the seal. A press tool is needed to safely remove the old seal and seat the new one evenly—critical for preventing leaks.
• Replacement Signs: Replace if you notice oil spots under the vehicle (near the axle), low gear oil levels, or unusual axle noises (signs of insufficient lubrication).
• Maintenance Tip: Always replace the axle seal when servicing the axle or drivetrain—old seals can harden or crack, leading to immediate leaks after reassembly.
