braking vibration, knocking after acceleration

Firstly, I have a really bad vibration throughout the car when braking. NOt Always.. just sometimes.. the rotors are fine, the brake pads are new.. could it just be a steering alignment that I Need?

whenever i accelerate heavy, then let off the gas, the engine has a knocking sound as the rpm's die down.. it does it whenever in gear or in neutral or park.. not sure what's causing it

any ideas?

bearing on the way out

Yup its the bearing. Same thing happened to me over a year ago. You better start looking for a new (or used) engine or a really goo engine shop that could rebuild yours. When I was shopping around it was looking like aroung $1500 to $4000 depending on what you want to have done. But I do live in LA and it seems as though everything is more expensive here.
