front end of my s-10 blazer

I have a 94 s-10 blazer and when I take off or when I brake it feels like the front end is floating and I have no control on the steering for a split second. I have changed all the ball joints already. The next thing I thought I would chane is the steering control arm. the only other thing I can think of is maybe a bolt on the A arm has broken but I can't see it. Has anyone any idea's on this or do they know anyone who has had this problem? Thanks

I had a problem like that and my problem was my stabalizer bar was somewhat loose, i would see if you have any loose bolts, if not then hopefully you have a friend that is a mechanic you can talk to.
