WHAT IS AN AXLE SEAL LEAK?

 


An axle seal leak occurs when the seal at the end of the axle housing fails to properly contain the lubricant (typically gear oil) within the axle assembly. This can happen due to wear and tear over time, exposure to harsh conditions, or improper installation.

The picture above shows a leaky axle seal. You can see the discoloration surrounding it due to the oil leak. This leak was discovered by experienced mechanics at our Car Repair Shop in Astoria when the vehicle was brought in for service. When the seal fails, gear oil can leak out of the axle housing, leading to several potential issues.

First, there is a loss of lubrication. The primary function of the gear oil is to lubricate the moving parts within the axle assembly, including gears, bearings, and shafts. A leaky axle seal can result in insufficient lubrication, leading to increased friction, heat, and wear on these components.

Secondly, there can be contamination. An axle seal leak can also allow contaminants such as dirt, water, and debris to enter the axle housing. This contamination can further accelerate wear on internal components and degrade the performance of the axle assembly.

Thirdly and more importantly, there are safety concerns. A significant leak of gear oil can create a hazard on the road, as it may cause the vehicle to lose traction or control. Additionally, if the gear oil leak is close to hot components like exhaust parts, it could pose a fire risk.

If you suspect an axle seal leak, it's important to address it promptly to prevent further damage to your vehicle. This typically involves identifying the source of the leak, which may require visual inspection or the use of specialized tools to detect leaks. Once the leak is located, the damaged seal should be replaced with a new one, and the axle assembly may need to be cleaned and inspected for any signs of damage or wear. It's advisable to have a qualified mechanic or technician handle the repair to ensure it's done correctly and safely.

Experienced mechanics at our Car Repair Shop in Astoria perform all of the above tasks. All our work is backed by a 3 year / 36,000 mile warranty on parts and labor, wherever you go.

WHAT ABOUT A REAR AXLE SEAL LEAK?

A rear axle seal specifically refers to the seal located at the rear axle of a vehicle. It serves the same purpose as any other axle seal: to prevent the leakage of lubricant from the axle housing and to keep contaminants out.

In most vehicles with rear-wheel drive or four-wheel drive, the rear axle seal is located at the end of the axle housing where the axle shaft exits. This seal prevents gear oil from leaking out of the differential or axle housing and ensures that the bearings and other components within the axle assembly remain properly lubricated.

If a rear axle seal fails, it can lead to leaks of gear oil, which can damage other components of the vehicle's drivetrain, suspension, and braking systems. Additionally, it can pose safety hazards due to reduced lubrication and potential loss of control.

Replacing a rear axle seal typically involves removing the axle shaft, removing the old seal, installing a new seal, and reassembling the axle assembly. It's important to follow manufacturer recommendations and use high-quality replacement seals to ensure proper function and longevity. Regular inspection and maintenance of rear axle seals can help prevent costly repairs and ensure the safe operation of the vehicle.

Experienced mechanics at our Car Repair Shop in Astoria will inspect your car and real axle seal to see if there are any leaks. Depending on the make and model of your vehicle, it can be quite a bit of work to get to the rear axle seal, but it is very necessary.

THE IMPORTANCE OF VALVE COVER GASKETS

Image
    As a very popular and established Auto Mechanic in Queens , we always educate our customers about the importance of regularly changing the engine oil because of the number of moving parts that depend on oil for lubrication. We regularly remind them to have it done per the maintenance schedule of their vehicle. One of the important parts that aids in oil lubrication is a valve cover gasket. To prevent oil from leaking out, the valve cover is placed on top of the engine. Underneath the valve cover, there is a gasket providing additional sealing, so when the engine is running no oil leaks out. There are a variety of valve cover gaskets, made of either cork or rubber. The rubber ones are the better since they eventually fit themselves to the cover over time. How do you know if you your car has a broken valve cover gasket? The first is leaking oil, not just under your car, but soaking the engine as well causing the smell of burning oil as it hits the hot engine. Consequen...
