i had shaking while driving and cluncking noises also. went to put on new rims and tires and noticed that the front left wheel was loose and alot of play in it. im sure its the wheel bearings. my question is do i have to change the whole assembly or is there a way to take it apart and just change the bearings out. im taking it to the meineke shop and have them do it but want to know this first. please reply quickly as i am going to leave here momentarily.
