When Does the Front Axle Shaft Seal Need to Be Replaced? 

In a car, the front axle shaft seal is the part that seals the connection, preventing fluid from the differential leaking over the axle. Power flows from the differential to the wheels, making the wheels turn. Lubrication is needed to keep the process running smoothly. Depending on your car’s design, the front axle shaft seal attaches to the differential case or axle shaft tube.

How Do You Know if a Front Axle Seal is Broken?

You’ll probably notice transmission or gear oil leaking onto the driveway. The reddish-brown liquid may be noticeable on the floor behind the front wheels, although leaks occur more frequently while driving. As the leak continues, you’ll notice that the transmission or differential fluid is low. It’s important to get help if you notice these signs or you risk permanently damaging the transmission.

When Should You Replace the Front Axle Shaft Seal?

The front axle shaft seal should be replaced as soon as you notice a leak. If left, further damage is possible to the brake components.

Is It Safe to Drive with a Leaking Front Axle Seal?

This depends on the current severity of the leak. If significant fluid loss is being produced from the leak, this means potential damage to the differential or transmission unit. It’s advised to get a repair immediately. If the leak is minimal, keep the differential oil and transmission fluid topped up and get a repair as soon as possible.

How Important is it to Replace a Compromised Axle Shaft Seal?

Can You Repair the Axle Shaft Seal Yourself?
