Differential Bearing and Seal Kit Buyer’s Guide
- A differential bearing and seal kit consists of the components needed to repair or replace faulty differential parts.
- Both the differential bearing and seal are made to provide a long service life, but regular wear and tear can accumulate over time and cause them to fail.
- You will need a differential bearing and seal kit if your differential oil is leaking and you’re noticing strange noises and sensing excessive vibrations from the differential when driving.
- The ideal kit must be durable, contain components that are compatible with your ride, and have a product warranty.
- An aftermarket differential bearing and seal kit usually costs around $50 and $300.
Every vehicle is an engineering marvel. Each one is equipped with an engine that ignites the air-fuel mixture inside the combustion cylinders to power the up and down motion of the pistons. This motion, with the help of several mechanical components, is converted into the rotational movement of the wheels that enables the vehicle to run. Of course, to make this process smooth and efficient, there are several other things that run in the background. One of them is the distribution of the engine’s torque to the wheels.
The differential is the system that gives the wheels sufficient power to spin at different speeds. This makes the inside wheels rotate slower than the outside wheels. If the differential is not working properly, it can be due to several faulty or worn-out components like the wheel bearing and seal. Hence, you’ll need a differential bearing and seal kit to get it back in shape.
What Is an Axle Differential Bearing and Seal Kit?
A differential bearing and seal kit contains all the components you need to successfully replace your vehicle’s worn-out differential bearing and seal. Typically, it consists of several parts, such as differential bearings, gear marking compound and brush, thread locker, sealer, pinion shims, differential shims, and more. These components are designed to match the specifications of your factory-installed differential assembly parts, making them ideal replacements.
How Long Does a Differential Bearing and Differential Seal Last?
The differential bearing and seal, which are essential parts of the differential system, are made to provide a long service life. They are made from heavy-duty raw materials that can withstand the daily wear and tear that comes with the job. More often than not, it will take years before you need to replace the differential bearing and differential seal in your vehicle. However, as your vehicle racks up mileage, the damage from everyday use can accumulate and cause both of these components to wear out. When that happens, you’ll need to replace them to keep the system in top condition.
Signs That You Need a Differential Bearing and Seal Kit
Disregarding a bad differential bearing and seal can eventually cause damage to your vehicle’s differential. If you don’t want to deal with the effects of worn-out differential parts, be sure to make the necessary replacement once you notice the following signs of failure:
Differential oil leak
One of the telltale signs that you need a differential bearing and seal kit is differential or gear oil leaks, which form puddles under your vehicle. The differential oil looks similar to your engine oil. To distinguish them, check where the leak is coming from. A good rule of thumb is that if the leak is coming from under one of your axles, there’s a big chance it’s a differential leak. You need to fix this problem as soon as you can to prevent it from damaging the wheels, axles, drivetrain, or transmission of your vehicle.
Similar to your other car components, a failing differential can produce loud whirring or rattling noises. So whenever you hear a strange sound coming from your vehicle’s differential, it’s best to have it checked by a professional mechanic immediately. This way, you can fix issues before they get out of hand and prevent potential problems.
You may notice excessive vibrations from your vehicle when you are driving if you have a faulty differential bearing. You may also hear a rumbling sound whenever you try to speed up. Fixing this problem before it can damage other differential components is a must. However, similar to leaks, vibrations can be caused by other bad parts. If you want to make sure that they’re caused by the differential bearing, have your ride checked by a mechanic.
Things to Look for in Your Replacement Front and Rear Differential Bearing Seal Kit
The function of the differential involves a lot of wear and tear. If you want your differential bearings and seals to last, get a kit with components made from heavy-duty raw materials. Make sure that you are investing your hard-earned money on parts that won’t easily fail.
If you want differential bearings and seals that can directly replace your stock components, look for a kit that is made to the exact specifications of your vehicle’s year, make, and model. A perfect fit can save you or your mechanic from any hassle during the installation process.
An excellent brand warranty doesn’t just give you peace of mind with extra protection. It also indicates that the kit’s manufacturer is confident of its product’s quality and durability. So go for a kit that comes with excellent warranty coverage.
