I did some searching on this and didn't really find a similar problem.

I'm getting a "floating" feeling from the front end when accelerating. I feels like a rocking left to right.

Any ideas?

Thanks!

what kind of rocking? motor mounts? more info

It's hard to describe. It's like it sways back and forth just slightly left to right when going out of a dead stop. Once you get to 45 or so it's smooth. Braking is also smooth. I don't know how else to describe it.

I have read a few posts aobut a steering box mod, but don't know if this is what I am experiencing or not.

it's pullin towards one side? wha is it that ur tryin to describe? does it jump when you step on the brake and move the shifter in differnt gears? or only whne ur moving?

No.

On accelaration, the front end slightly rocks from left to right. It's not a pull that you would get from tire ware. If you look at the hood, it just kind of "floats" from side to sidt. It's very slight.

I don't know any other way to expalin. Sorry.

is the hood floating side to side or is ur car floating side to side?

The car. It's something in the front suspension.

Ball joints are ok. I'm guessing something with the steering box?

CHeck out your tie rod. IT could be that it's loose (i found mmy driver side loose when i went checked it).
