Hi, having an issue with a vibration/sound inside the car when driving. Mostly noticeable at speeds 45km/h - 65km/h. The sound does get faster depending on speed. I am also suffering brake shudder and both problems feel like they are coming from the drivers side rear. I am wondering if there is a problem with wheel bearings but not really sure? So went around and jacked up the car and had a listen while spinning each wheel. They all have a slight sound while spinning. I posted the most noticeable one in the video below. If you can help, it will be much appreciated. Maybe i need to take off wheels, rotors, calipers to assess problem better?

anyone know if this is the sound of damaged wheel bearings?

First of all, what year, model is your car? Might help if everyone knows what car they are looking at.

Secondly, from the video...the sound you hear is actually the brake disc rubbing on the brake pads. Nothing to worry about.

Thirdly, brake shudder means the discs are most likely warped. Either get them machined and new pads put in or just get the whole discs and pads replaced.

Fourthly, vibrations could be due to tailshaft out of balance, wheels out of balance (may have lost a weight along the way), uneven tyre wear etc.

Finally...if it is an E-series (not sure how it works on AU/BA onwards). Jack the car up again, hold the wheel at the 12 and 6 o'clock position and try to rock/tilt it in the vertical. If there is a lot of play then the bearings might be rooted and require replacement. If there is no movement (or very very little) you should be safe.

Hope that helps.

Usually brake shudder is the front due to most of your braking done by front calipers. BA's do have a problem with front rotors and disc pads and maybe you need to look into that first? also, take a look at the front hubs, the bearing is a part of it and they may be worn?

As to your Rear problem, maybe the problem is with the hand brake shoes? they may not be adjusted properly, this is better done by a mechanic if you have not done them befoe.
