Output Axle Seal Kit – 1108557-00-A

Tesla Model S3XY – Output Axle Seal – 3DU 40×67

Replace your leaking Tesla axle shaft output seal with this OE-style 3DU output axle seal (40×67).
Designed as a direct replacement for Tesla part number 1108557-00-A, it restores proper sealing at the drive unit output, keeping lubricant in and contaminants out on Model S, 3, X, and Y applications.

Why these seals fail

• Heat & mileage – Constant heat cycles and high torque eventually harden the seal lip.
• Contamination – Road debris and fine particles can score the sealing surface over time.
• Incorrect installation – Misalignment or improper tooling deforms the seal during install.
• Aging elastomer – Older seals lose elasticity, leading to seepage at the axle interface.

Our solution

• OE-style geometry – Matches Tesla dimensions for a proper press fit in the drive unit housing.
• Correct 3DU sizing – 40 mm ID × 67 mm OD as used on 3DU/4DU output shafts.
• Leak-stop fix – Helps eliminate gear oil seepage at the axle output before damage occurs.
• Multi-model coverage – Fits select Model S/X Raven & Long Range/Performance, plus Model 3/Y front and rear drive units.
