If the center support bearing of your car's driveshaft is worn, also known as the Flex Disc, you may experience transmission issues or noises during acceleration. The flexible disc connects the driveshaft to the transmission, while the center support bearing keeps the driveshaft aligned and prevents excessive play when it rotates.

This is not a very difficult job to perform, and it is advisable to do it without removing the exhaust. Raise the car and remove the transmission cover.

Then remove the two rear wheels. The flexible disc is connected to the back of the transmission.

You will need to separate the driveshaft and then remove the retaining ring that holds the bearing. Then simply tighten the nuts and reassemble everything.

How to Reset the Tyre Pressure Warning Light on a Kia Rio?

Once all tyres have been inflated to the recommended pressure, turn on the ignition to check that the light has disappeared: if it is still present, it may be necessary to drive for a few miles, allowing the sensors to work and thus turning off the light.
