Differential Bearing Guides

Differential Bearing Buyer’s Guide

Summary:

  • This differential distributes the power delivered by the drivetrain between the driver and passenger side drive wheels.
  • Helping support the shafts going into the differential, allowing these to move smoothly, and preventing these from grinding against the differential case are the differential bearings.
  • Bearings are components used in machines to reduce the friction between the moving and non-moving parts, protect the stationary components from the active elements, assist in the rotation of the moving parts, and keep the supported parts in the proper position.
  • The most common type of bearing that is used as a differential bearing is the rolling bearing.
  • Differential bearings need to be able to handle both radial and axial loads since these not only support the propeller and drive wheel shafts, but also the load of the vehicle.
  • While the race of the bearings help hold the shafts in place and ensure that the gears stay properly meshed, the rolling elements between the rings allow the axles to spin smoothy.
  • Bad differential bearing noises include whining, whirring, rumbling, howling, and a low-pitched sound heard at certain conditions.
  • The symptoms of worn or failing differential bearings might also be similar to that of other differential components that are malfunctioning. A professional can make an in depth examination and will be able to identify if the broken component is the differential bearing or if it is a different part of the assembly.
  • When getting a replacement differential bearing, or any other car part for that matter, always take into account your vehicle’s make, model, and year.
  • In the case of differential bearings, while these may seem similar to other bearings, it is critical to get replacements that meet the specifications for the original part.
  • Depending on the type and number of differential bearings you’ll need, the part itself can cost from around $8 to $125 for an aftermarket replacement. It can be bought individually, in sets of two, or in a kit.

For driving to be easy and riding to be smooth, the drive wheels should be able to spin independently from each other, especially in situations such as when making a turn or when the drive wheels are on different terrains. The component of the drivetrain that allows this to happen is an arrangement of gears called a differential. This gear assembly distributes the power delivered by the drivetrain between the driver and passenger side drive wheels.

Depending on the type of drivetrain, a vehicle can have from one up to three differentials. The component is located between the axle of the drive wheels and is connected to the engine via the propeller shaft. Helping support the shafts going into the differential, allowing these to move smoothly, and preventing these from grinding against the differential case are the differential bearings.

What Is a Differential Bearing?

There are many kinds of bearings used in vehicles, and the differential bearing is just one of these. This bearing is located on the sections of the differential casing that accommodate the propeller shaft and the drive wheel axle half shafts.

Basically, bearings are components used in machines to reduce the friction between the moving and non-moving parts, protect the stationary components from the active elements, assist in the rotation of the moving parts, and keep the supported parts in the proper position. The main types of bearings are plain, which is just a ring that has the other machine part rotating inside it, and rolling, which has a pair of different sized rings or races with rotating elements in between.

The most common type of bearing that is used as a differential bearing is the rolling bearing. This type can be identified by the kind of rotating element it has—whether it features balls or cylindrical rollers.

Depending on the type, bearings are designed to be able to support either or both radial load and axial load. When the force being applied is perpendicular to the bearing’s axis of rotation, then it is called a radial load, but if the force is parallel then it is an axial load, or what is also known as thrust. As for differential bearings, these need to be able to handle both radial and axial loads since these not only support the propeller and drive wheel shafts, but also the load of the vehicle.

How Do Differential Bearings Work?

The shafts connecting to the differential gears pass through the inner ring of the differential bearing, and it is the outer ring that comes into contact with the differential casing. While the race of the bearings helps hold the shafts in place and ensures that the gears stay properly meshed, the rolling elements between the rings allow the axles to spin smoothly.

It is the shape of the rolling elements, which could either be spherical or cylindrical, that minimizes friction between the moving and non-moving parts. Since the rolling elements are curved, they do not lie flat against the rings and the point of contact is less.

Bad Differential Bearing Symptoms

Due to the location and purpose of the differential bearings, issues with this part can affect the operation of the differential. The symptoms of worn or failing differential bearings might also be similar to that of other differential components that are malfunctioning. A way to tell if there is a problem with the differential bearing is through sound. Bad differential bearing noises include whining, whirring, rumbling, howling, and a low-pitched sound. The unusual sounds can be heard at certain conditions.

Whining

As the vehicle is accelerating or decelerating, the whining noise will increase and peak at a narrow speed range.

Whirring and Rumbling

The vehicle will emit a whirring or rumbling sound while traveling at speeds faster than 20 miles per hour (mph) and the pitch of the sound may change while cornering or turning. There can also be a whirring noise at different speeds or while decelerating.

Howling

Accelerating or decelerating over a wide range of speeds will result in a howling noise.

Low-pitched Sound

A low-pitched sound that doesn’t change can be heard while turning.

When your vehicle consistently makes these unusual noises under the mentioned circumstances, it would be best to see a mechanic. A professional can make an in depth examination and will be able to identify if the broken component is the differential bearing or if it is a different part of the assembly.

Differential Bearing Replacement

With the kinds of forces that are constantly putting pressure on differential bearings, this part may eventually wear out. While it may seem insignificant compared to other components, a differential bearing failure could make driving difficult. For instance, this could cause the shafts and the differential gears to misalign, resulting to power not being properly transmitted to the wheels. This could lead to more serious problems when not addressed immediately, such as the differential gears breaking prematurely. If you experience issues with steering and turning, and once your mechanic has determined that the problem is with the differential gears, it is important that you have these replaced as soon as you can to avoid more trouble.

When getting a replacement differential bearing, or any other car part for that matter, always take into account your vehicle’s make, model, and year. In the case of differential bearings, while these may seem similar to other bearings, it is critical to get replacements that meet the specifications for the original part. Remember that differential bearings support the propeller and drive wheel shafts and are subject to both radial and axial loads, so the replacement should be able to handle the same amount of load as the worn part. The shafts should also fit perfectly into new differential bearings to avoid unneeded movement and misalignment.

Differential Bearing Replacement Cost

Depending on the type and number of differential bearings you’ll need, the part itself can cost from around $8 to $125 for an aftermarket replacement. It can be bought individually, in sets of two, or in a kit.

How to Replace Your Vehicle's Differential Bearing

Do you want to have a one-of-a-kind road trip? Then you must take care of each and every component of your vehicle! Remember that even the smallest parts can make or break your vehicle. Your differential bearing is a good example. It helps the axles to prevent friction to give you a smooth ride at any given time. Changing your differential bearing is not a problem. You can indeed do the task yourself. Here are the tools and steps that you will need:

Difficulty level: Difficult

Things you'll need:

  • Floor jacks and jack stands
  • Drain pan
  • Socket and ratchet
  • Wrench
  • Slide hammer
  • Bearing puller
  • Gear oil
  • Sealant
  • Clean rags
  • New differential bearing

Step 1: With the help of floor jacks and jacks stands, lift and support the rear portion of your vehicle. This will allow you to have proper access to the differential bearing while keeping your vehicle steady.

Step 2: Look for the differential drain plug or cover on the rear underside of your vehicle. Loosen and remove its bolts with the help of a ratchet afterwards.

Step 3: Since the drain plug contains oil, prepare a drain pan and place it underneath. This will be responsible in catching excess fluid. Store the differential cover in a safe area after draining most of the fluid.

Step 4: The next part that you need to remove is the axle shaft before you can see the differential bearing clearly. Using a socket and ratchet, remove the axle clips. Store the axle shaft as well.

Step 5: You may now remove the old differential bearing. To do this, insert a bearing puller into the bearing of the left side axle. To remove the differential bearing completely, use a slide hammer. Do the procedure for the right side also.

Step 6: Before installing the new differential bearing, lubricate it with gear oil first. This can help to prevent premature corrosion of the bearing.

Step 7: You may now install your new differential bearing in place. To do this, hold and line up the first bearing onto the left side, and attach with a bearing installer and the slide hammer. Again, do the same procedure for the bearing that must be mounted on the right side.

Step 8: This time, you can start reinstalling the components that you have removed earlier in reverse. Bolt the axle shaft and the clips back into place first.

Step 9: Before you reattach the differential cover back to its mounting area, wipe the surface with clean rags first to ensure that it will be sealed securely.

Step 10: You may now fasten the differential drain plug or cover with the help of a sealant. Remove the drain pan that you have placed underneath it.

Step 11: Refill the differential drain plug with fresh fluid. Make sure that all its fastening bolts are properly secured into place.

Step 12: You may now remove the floor jacks and jack stands on the rear portion of your vehicle, so you can verify the efficiency of your new differential bearing upon starting the engine.
