Differential lubricant can leak from axle seals, the pinion seal, a cover gasket or sealant joint, or a damaged housing. A blocked vent or worn components may also contribute to leakage.
The wettest visible area is not always the source because fluid can spread as the vehicle moves. An inspection helps locate the leak and determine whether related wear needs attention.
If you see fresh spots where you park in Council Bluffs, contact Certified Transmission at 2112 West Broadway. Checking the lubricant level and correcting the cause helps reduce the risk of additional damage.
