I have been having problems with my hood on my 1978 Chevy Suburban. When driving down the highway it bounces up and down. Could anyone enlighten me as to why it would be doing this? Thank you. sincerely, Chris

 

is the hood shutting down all the way or it could be the hook in the front is bad.

 

try ajusting the latch or look at the shape of the rubbers at the corners of the rad cratle to see if they are worn if they are you might try getting new ones or just twist them up a bit so the hood hits a bit harder on them and it pushes the hood a bit tighter against the latch. hope this helps.
