How to replace a sealed, pre-adjusted, and pre-lubricated double-row roller wheel bearing on Audi A3?

The bearing is a pre-lubricated and pre-adjusted sealed, two row roller bearing that does not need any maintenance and is attached to the wheel bearing housing by bolts. First of all, take out the wheel trim or hub cap (where applicable) and loosen the drive shaft retaining bolt as the vehicle is on the wheels without loosening it more than 90 degrees, to prevent damaging the wheel bearing. Relax the wheel bolts, use the handbrake, jack the front of the car and place it on axle stands then remove the front roadwheel. Unscrew and take out the retaining bolt of the driveshaft then the ABS wheel sensor. Then quartz, you can take off brake disc, that is, take off the brake caliper, but do not break the hydraulic brake hose, tie the caliper on the front suspension coil spring to take off the strain on the hose. Unscrew the splash plate of the wheel bearing housing, press the driveshaft outer stub against the transmission and unscrew the wheel bearing retaining bolts of the rear of the housing. Take the hub and wheel bearing with full hub out of the outside of the housing and slide it off the splines of the driveshaft. Install the new wheel bearing in the housing and lock the splines of the hub to the outer stub of the driveshaft, and replace the splash plate and tighten the bolts. Install the brake disc and caliper then the ABS wheel sensor. Make the driveshaft outer stub completely inserted into the hub and screw a new hub bolt in, by hand at this point. Make sure that the outer joint has been pushed into the hub, and then re-fit the roadwheel. Fasten the driveshaft securing bolt to the correct steps as stated with an angle gauge to make the right adjustments and do not permit the car to support itself on the wheel bearing since it may cause harm to the wheel bearing. Lastly, lower the car to the road, screw the road wheel bolts and install the wheel cover or hub cap.

How to remove and install the front wheel bearing and wheel hub assembly on Audi A4?

The driveaxle/hub bolt should first be loosened in order to remove the driveaxle and hub assembly. Next, loosen the wheel bolts and lift the vehicle using jackstands and make sure the vehicle is well supported on jackstands, followed by removing the wheel. The second step is to remove the brake caliper, caliper mounting bracket, and brake disc, making sure not to drop the brake caliper but to hold it with the use of wire or rope. Take off the shield by removing the shield mounting bolts and lose the upper control arms by removing them by unscrewing the steering knuckle. Gently insert the knuckle assembly and push the driveaxle out of the hub, it may be necessary to give the CV joint a stroke with a soft-faced hammer out of the hub or a puller may be needed, should the knuckle assembly not push free. Prop the driveaxle, do not overextend the inner CV joint. Lift off the mounting bolts of the hub/bearing assembly at the back of the steering knuckle and lift out the hub/bearing assembly. When it comes to bearing replacement, it is a job that needs professional skills and special tools that may not be available among some people and it is therefore good to trust a professional mechanic. Installation requires the mounting surfaces of the steering knuckle and the driveaxle splines to be smooth and without burrs and nicks and then the hub/bearing assembly should be attached to the steering knuckle and the bolts should be tightened to the recommended torque. Apply grease on the driveaxle splines and attach it to the hub/bearing assembly and install a new driveaxle/hub bolt without tightening it. Re-attach the upper control arms to the steering knuckle, re-fit clamp bolt and self-locking nut and tighten the nut pushing both control arms downward to avert misfitting of the balljoint studs. Install the caliper, caliper mounting bracket and brake disc, attach the fasteners to the recommended torque. Lastly, fit the wheel, dismount the jackstands, and drop the vehicle, then squeeze the driveaxle/hub bolt by positioning an assistant on the brakes, and then screw in the wheel bolts to the advised torque.

Audi Wheel Bearing

Audi Wheel Bearing keeps each wheel rolling with silky smoothness, working to support the weight of the vehicle while reducing friction to keep steering, braking, and ride comfort precise. Across the entire Audi range, this small component lives within a sealed housing, its sleek balls or tapered rollers turning silently to prevent the build-up of heat and unwanted vibrations while the hard-working seal protects the grease from water and dirt, which extends service life and makes the Wheel Bearing a mute guardian under every fender. Because the assembly helps to maintain proper alignment, it helps tires wear evenly, and because electronic aids like ABS receive clean signals, it's proof that a well-designed Wheel Bearing plays a direct role in safety in addition to performance. Matching that hidden strength, Audi as a brand delivers visible thrills, from the legendary Quattro all-wheel drive that claws confidently through rain or snow to sharp handling sedans and SUVs that balance comfort with athletic poise. The Virtual Cockpit presents high-resolution gauges, matrix LED headlights cut through the dark, e-tron models showcase silent electric acceleration, and the same four-ring badge that traces its heritage to 1909 and Auto Union racing glory. Continuous research into electrification and assisted driving keeps Audi at the cutting edge, and the durable Wheel Bearing adds to this innovation by ensuring that every mile, powered by turbo engines or batteries, is smooth, stable, and unmistakably Audi.

Audi Wheel Bearing Parts and Q&A

Hub & Bearing
5K0-498-621-A
Q: How to replace a sealed, pre-adjusted, and pre-lubricated double-row roller wheel bearing on Audi A3?
A:
The bearing is a pre-lubricated and pre-adjusted sealed, two row roller bearing that does not need any maintenance and is attached to the wheel bearing housing by bolts. First of all, take out the wheel trim or hub cap (where applicable) and loosen the drive shaft retaining bolt as the vehicle is on the wheels without loosening it more than 90 degrees, to prevent damaging the wheel bearing. Relax the wheel bolts, use the handbrake, jack the front of the car and place it on axle stands then remove the front roadwheel. Unscrew and take out the retaining bolt of the driveshaft then the ABS wheel sensor. Then quartz, you can take off brake disc, that is, take off the brake caliper, but do not break the hydraulic brake hose, tie the caliper on the front suspension coil spring to take off the strain on the hose. Unscrew the splash plate of the wheel bearing housing, press the driveshaft outer stub against the transmission and unscrew the wheel bearing retaining bolts of the rear of the housing. Take the hub and wheel bearing with full hub out of the outside of the housing and slide it off the splines of the driveshaft. Install the new wheel bearing in the housing and lock the splines of the hub to the outer stub of the driveshaft, and replace the splash plate and tighten the bolts. Install the brake disc and caliper then the ABS wheel sensor. Make the driveshaft outer stub completely inserted into the hub and screw a new hub bolt in, by hand at this point. Make sure that the outer joint has been pushed into the hub, and then re-fit the roadwheel. Fasten the driveshaft securing bolt to the correct steps as stated with an angle gauge to make the right adjustments and do not permit the car to support itself on the wheel bearing since it may cause harm to the wheel bearing. Lastly, lower the car to the road, screw the road wheel bolts and install the wheel cover or hub cap.

Next, loosen the wheel bolts and lift the vehicle using jackstands and make sure the vehicle is well supported on jackstands, followed by removing the wheel. The second step is to remove the brake caliper, caliper mounting bracket, and brake disc, making sure not to drop the brake caliper but to hold it with the use of wire or rope. Take off the shield by removing the shield mounting bolts and lose the upper control arms by removing them by unscrewing the steering knuckle. Gently insert the knuckle assembly and push the driveaxle out of the hub, it may be necessary to give the CV joint a stroke with a soft-faced hammer out of the hub or a puller may be needed, should the knuckle assembly not push free. Prop the driveaxle, do not overextend the inner CV joint. Lift off the mounting bolts of the hub/bearing assembly at the back of the steering knuckle and lift out the hub/bearing assembly. When it comes to bearing replacement, it is a job that needs professional skills and special tools that may not be available among some people and it is therefore good to trust a professional mechanic. Installation requires the mounting surfaces of the steering knuckle and the driveaxle splines to be smooth and without burrs and nicks and then the hub/bearing assembly should be attached to the steering knuckle and the bolts should be tightened to the recommended torque. Apply grease on the driveaxle splines and attach it to the hub/bearing assembly and install a new driveaxle/hub bolt without tightening it. Re-attach the upper control arms to the steering knuckle, re-fit clamp bolt and self-locking nut and tighten the nut pushing both control arms downward to avert misfitting of the balljoint studs. Install the caliper, caliper mounting bracket and brake disc, attach the fasteners to the recommended torque. Lastly, fit the wheel, dismount the jackstands, and drop the vehicle, then squeeze the driveaxle/hub bolt by positioning an assistant on the brakes, and then screw in the wheel bolts to the advised torque.
