I have a 96 honda prelude Si dropped on some skunk 2's... well when im driving my car is driving fine then sometimes it just starts to shake like foward to backward and foward like the car isnt getting into gear or something but i already am in gear... and i also hear like a knocking or rubbing sound from like my axels when i get to about 3k rpm 1-3rd gears so what do you think the problem is?

 

Could be a lot of things. How low are you dropped?
