Output Axle Seal Kit – 1108557-00-A

Drive Unit Output Shaft Seal – Front Raven Model X

This drive unit output shaft seal is an OE-style replacement for the front Raven drive unit on Tesla Model X, built around the factory specification 1108557-00-A. Use it to repair leaks at the axle/output interface and
restore proper lubrication control in the front Raven drive unit assembly.

Why these seals fail

• High torque loads – Instant EV torque works the seal lip and bearing surfaces over time.
• Heat & aging – Repeated heat cycles harden the elastomer and reduce sealing performance.
• Contaminants – Road splash and fine particles can score the shaft or sealing surface.
• Improper installation – Cocked or over-driven seals deform and leak prematurely.

Our solution

• OE-style geometry – Matches Tesla’s 1108557-00-A design for proper fit in the front Raven housing.
• Correct shaft interface – Sized for the front Raven Model X output shaft to maintain a tight, uniform seal.
• Leak-stop repair – Targets gear oil seepage at the front drive unit axle output before it becomes a major failure.
• Shop & DIY friendly – Ideal for independent EV shops and experienced owners servicing Raven front drive units.
