How to Replace Center Support Bearing?

Before delving into the nitty gritty of this article, its worthy of mention to outline the signs which justify a faulty center support bearing prior to its replacement.

Symptoms of Center Support Bearing Failure

There are three common indicators that signal a faulty center support bearing to an operator, in cases where the bearing is worn out or damaged. They are:

Vibrations: Shakings experienced due to loosened center support bearing, basically when the vehicle attempts to get into motion after coming to complete rest.

Binding feeling: It is the impediment of smooth vehicle movement as a result of dry u-joint, hence causing resistance during driving.

Unusual noises: Grinding, squealing and howling noises encountered upon acceleration or deceleration of vehicles as a result of rusty, dry or worn-out bearing.

Factors to Consider Prior to Center Support Bearing Replacement

Physical Inspection

• Examining the bearing for any sign of wear and tear is key so as to ascertain whether to reuse or replace entirely with a new one.

Size and Type of Bearing

• Paying meticulous attention to the correct size and type of bearing as this factor is relative to the functionality of the vehicle model using it.

Construction Material

• Materials such as steel, plastic, aluminum are utilized in bearing construction therefore there’s need to choose a suitable bearing according to the vehicle model to ensure optimal performance.

Check if Bearing is Sealed or Unsealed

• Bearing may be rubber sealed or unsealed which determines the maintenance to be proffered for the bearing; rubber sealed bearings are verified for any sign of crack on them that can impede performance while unsealed will need lubrication for continuous function.

Replacing the Correct Center Support Bearing

Required Tools

Removing a faulty bearing will need the deployment of required center support bearing removal tools- socket set, wrench set, bearing puller, pry bar and slide hammer. So, begin by first of all gathering these tools as they to significant extent help in the effective removal of the bearing without causing damage to its component parts.

Procedures:

Preparation

After gathering the required tools, ensure the vehicle engine is turned off with the battery disconnected, so as to prevent any chance of electric shock occurring.

Lifting the Vehicle

Upon justification of these factors for bearing replacement, the next line of action is securely placing the vehicle on jack stands and lifting it for a good elevation before continuing with other procedures.

Finding the Driveshaft

Under the vehicle locate the front and rear driveshafts together with their yokes- transmission and rear differential respectively and mark their points of attachment for easy alignment during reassembly.

Remove the Driveshaft

In case the driveshaft is rusty, spraying rust penetrant helps in loosening the bolts securing them tightly to their yokes. Allow the penetrant to stay for some minutes before using the socket sets to loosen the bolts. Use the slide hammer on weld marks that tend to create obstruction without hitting the driveshafts. Remove the driveshaft and set aside.

Separate the Driveshafts into Halves

Confirm the center support bearing position and the mark the area that faces the front and rear driveshaft respectively. Using the pry bar and wrench sets of best fit, separate the driveshaft into halves by loosening the bolts linking them to the center support bearing. Carefully detach the driveshafts to avail the center support bearing.

Removing the Old Center Support Bearing

After pulling the driveshafts apart, the center support bearing is usually clinked to the rear driveshaft. Therefore its removal requires hitting it with a slide hammer without hitting the rear.

Replacing with New Center Support Bearing

During the installation of the new center support bearing, it’s ideal to lubricate the rear driveshaft for easy sliding of the bearing and also rotating it to ensure it spins efficiently.

Reinstall the Front and Rear Driveshaft Components

The front and rear driveshafts are reinstalled back to their previous positions according to the markings made on their points of attachments. The bolts at the same time a securely tightened using wrench sets until there’s no room for them shaking around areas where driveshafts are in connection with the center support bearing.

Test for Correct Functioning

At this point it’s crucial so as to ascertain the overall wellness of the vehicle, by lowering it from the jack stands and taking it for a road drive while being on the look for indicators that signal a faulty center support bearing. If there isn’t any then consider the replacement process a success.

FAQ’s

How often should the center support bearing be changed?

It is ideal you change the bearing when you notice any indicator of a faulty bearing. Although change is recommended after every 50,000 miles.

Is replacing the center support bearing a mandatory service?

Definitely, yes. As this contributes to the optimal performance of the car and service life of the car overtime.

Conclusion

It’s advisable to stick to these step-by-step replacement procedures to get the best results, most especially for the longevity of the vehicle.
