Vibration problem

I get this really bad vibration problem where the car and mostly the wheel starts shaking really bad. It usually happens after going at high speeds, like downhill, and then braking. But don't think its brake because to make it stop I usually turn the wheel a certain way. It seems like something is out of place and then by moving the wheel, it gets back in place. Kind of hard to explain. Any ideas...?

First I would check with your tires, I have had this problem and one of my tires was bad. If not,get an alignment, they can check the tires there too, you might of hit a pot hole or a bump too hard and the all mighty f-bodies, adjust very easily to bumps. I also have experienced shaking brakage. The stock rotors suck on these and I have had to get these replaced and break them in correctly. These are my opinions, anything could be wrong. Let me know what it is. Thanks.

check your wheel alighnment your tires so they are balanced adn your wheel bearins that is most likly it if anythink but i would also check your link system but probly not that it could be as simple as wheels miss balanced :banghead:
