Subaru Front Transaxle Inner Axle Seal Kit LH 806735290 & RH 806735300 — OEM fit for Legacy Outback Forester Impreza WRX STi, stop

Genuine Subaru front transaxle output oil seal kit (LH 806735290 & RH 806735300) replaces worn axle seals to stop leaks and restore proper drivetrain sealing.

This OEM seal kit contains the left and right inner axle seals engineered for Subaru transaxles used across many Legacy, Outback, Impreza, WRX, STi, Forester, Tribeca, Crosstrek and Baja model years. Each component is manufactured to the automaker's specification so you get the correct fit, material hardness and lip geometry required to maintain fluid containment and protect bearings inside the transaxle. Using the right Subaru part reduces the need for repeated disassembly and avoids the compatibility issues that can arise with generic aftermarket seals.

Which Subaru models and years will these seals fit?

These two OEM inner axle seals are specified for a broad range of Subaru models across the 2003–2018 model years. Confirm fitment by matching part numbers or consulting your vehicle VIN and model year.

• Outback and Legacy: 2005–2018
• Impreza, WRX, STi: 2004–2018
• Forester: 2003–2018
• Tribeca: 2006–2014; Crosstrek: 2013–2018; Baja: 2004–2006

How do I know if I need these inner axle seals?

Common signs of a failing inner axle seal include visible oil seepage near the transaxle output, a drop in transaxle fluid level, or oil on the inside of the wheel or hub area. If you notice leaks after replacing CV axles or performing transaxle work, the seals may be worn or damaged and should be swapped for OEM replacements.

• Oil stains around the transaxle or wheel well indicate seal failure.
• Grease or oil on CV boots or inside the hub suggests a compromised seal.
• Replacing seals during axle or transaxle service prevents repeat leaks.

What’s included and how are these parts packaged?

This listing supplies one left-hand inner axle seal (part 806735290) and one right-hand inner axle seal (part 806735300), both new OEM components. Parts arrive sealed in factory packaging to protect the sealing lips and to preserve correct fitment tolerances.

• LH Inner Axle Seal — part 806735290 (quantity: 1)
• RH Inner Axle Seal — part 806735300 (quantity: 1)
• Factory-sealed packaging to prevent contamination in transit

Will these seals work with aftermarket axles or only OEM axles?

These Subaru OEM seals are designed to interface with the original transaxle output shaft dimensions, and they are compatible with most quality aftermarket axles that follow OEM shaft specifications. For best results, verify that the aftermarket axle's output spline and shaft shoulder match OEM dimensions before installation.

• Best compatibility with axles matching Subaru OEM shaft geometry.
• Helps prevent premature seal wear when shaft tolerances are correct.
• Ask your axle supplier for shaft measurements if unsure.

Who is this for: This kit is intended for Subaru owners, technicians and independent shops performing drivetrain or axle service on compatible Legacy, Outback, Impreza, WRX, STi, Forester, Tribeca, Crosstrek and Baja vehicles. Choose this OEM kit if you prioritize exact-fit replacement parts, want to avoid leak repeat visits, or are restoring a vehicle to factory specification. Always inspect related components—axle shaft condition, bearing surfaces and transaxle mating faces—when installing new seals to ensure a long-lasting repair.
