Somethings wrong with my car. On my front right wheel, it's making squeeking noise when the car is moving. Also, the car shakes at fast speeds and stops. I know it's now the brakes. When I took off the wheel today there was thick green grease everywhere. I don't know much about cars so I can't really decribe the problem, but there is definitely a tear on a rubber piece behind the brake. It seems to be coming out of there. Sorry I can't explain it any further, but does anybody have any idea what it is or had a similar problem? I just want to know what it is before I bring it to the shop and how much I should be expecting to pay. Thanks for any info.

I think it could be a cv boot or axle...i don't know.
