What happens when your rear differential leaks?
If the output seals leak to the point of running the differential low on fluid it may cause the differential to produce a howling, grinding or whining sound from the rear end of the vehicle.
How long can you drive with a leaking diff?
After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.
Can you drive with a diff leak?
If the leaking axle seal does not get fixed soon and the transmission is slipping, you could cause permanent damage to the transmission. If the leak is small and you can’t make it to an appointment for a few days, it is okay to drive your vehicle as long as you keep the transmission fluid full.
How to know if your vehicle has a differential leak?
A differential leak is not an uncommon leak on many vehicles equipped with a differential. But how do you know if your vehicle has a differential?
Where are the seals on a rear differential?
Some differentials put these seals just outside the bearings, while others have the seals all the way at the end of the axle tube. Due to different designs, your differential can leak from many different places making it difficult to determine the exact leak location. However, many people find that rear differential leaks are the most common.
Where does the lubricant go in a differential?
Like any lubrication, there are seals to keep the lubricants from running out of your differential. Some differentials put these seals just outside the bearings, while others have the seals all the way at the end of the axle tube.
Where does the differential go in a 4 wheel drive car?
Your vehicle has just one engine but must drive 2 or 4 wheels with that engine. Most four-wheel drive vehicles have a front and rear differential. For vehicles that are front wheel drive, the multiplication happens inside the transmission, which can technically be called a transaxle.

How do you replace a leaking differential gasket?
However, some axles have a cover plate at the rear of the differential. held on by screws or bolts. To replace a leaking gasket here, drain the oil, remove the screws, take off the plate, clean the mating surfaces and fit a new gasket.
Why does my rear wheel drive car leak oil?
This causes oil and air to build up inside, which may force oil out of leak-prone places. Overfilling the axle with oil can also raise the pressure enough to cause leaks. Some rear-wheel-drive cars with independent rear suspension may leak oil from the drive-shaft oil seals.
