The 2007 Jeep Liberty typically uses 75W-90 GL-5 gear oil in its differentials—the front Dana 30 and the rear Dana 35. If the rear axle is a limited-slip unit, include the appropriate friction modifier per the product instructions. Always verify the exact specification for your VIN in the owner's manual or on the axle tag.
Axle gear oil guidelines
These guidelines cover the lubricants used in the Liberty’s primary axles. Using the correct viscosity and specification helps protect gears and bearings, especially under extreme temperatures or heavy use.
- Front differential (Dana 30): 75W-90 GL-5 gear oil. Use friction modifier only if the axle is equipped with a limited-slip differential that requires it.
- Rear differential (Dana 35): 75W-90 GL-5 gear oil. If the rear axle has a limited-slip differential, add the recommended friction modifier per the product instructions. Some owners opt for 75W-140 synthetic in harsh climates or for longer service intervals; check the manual for guidance.
These recommendations align with common configurations for 2007 Liberties, but exact requirements can vary by trim and production date. Always confirm with your VIN-specific documentation or the axle tag.
Notes on other drivetrain fluids
Transfer case and transmission fluids
The transfer case fluid is not gear oil. Chrysler-era Jeep transfer cases generally require a specific automatic transmission fluid (ATF), such as Mopar ATF+4, rather than gear oil. The automatic transmission itself also has a designated ATF specification. Consult the owner’s manual or a dealer for the exact fluid specification by VIN.
Summary
For a 2007 Jeep Liberty, use 75W-90 GL-5 gear oil in both the front Dana 30 and rear Dana 35 differentials, with a friction modifier added if a limited-slip rear axle is present. Always verify exact requirements for your vehicle’s VIN in the manual or on the axle tag. The transfer case uses ATF, not gear oil, so keep fluids distinct and follow the factory recommendations for that component.
