Suspension question

check the

check your tq box area my old car was doing that noise when i was driving and it was a bad box

The front end lunge would suggest that it is not a problem with the sway bar, but I have broken so many sway bar end links, so that is the first place I would check. Typically a broken sway bar end link will give you problems when an individual wheel goes over a bump – it is a “side-to-side” or “roll control” suspension support element. But, none the less, they break so often, and they are cheap to replace, so I would look there first. The last time I broke one, I could hear a clunking noise when I pushed down on one of the front fenders.

If you remove one of the front wheels, you should be able to see (one of) the sway bar end links. They connect from the lower control arm to the sway bar. They are basically a long bolt that connects the lower control arm to the sway bar end, that is shrouded inside a cylindrical piece of tube. You might not see the break obviously at a glance, because it could be hidden by the hollow tube.
