Hey I have an 03 a4 been noticing vibrating in front of car over the last week seems like car is wobbling over an back in the front is this the cv joint?? And what parts do I need to replace? Also wen I'm driving on uneven surface there is a rattle from front of car all new arms in the car so this is not the arms have been told might b the break pads lose as it's a common problem has anyone had this prob and also wat needs to b replaced? Thanks

 

Also back to the rattle it goes away when I break.

 

If your rattle goes away when braking there is a problem with the brake pads , stay away from Chinese made crap!
The vibration could be the axles , the same goes for there country of origin!
