I have noticed over the past few months a faint clunk/thud noise during driving in our 91 accord. It is speed related, mainly showing up from 35mph-50mph. It may do it at higher speeds but may not be audible because of road/wind noise. It is not transmission related because I have put the car in neutral when coasting from 45mph down and you can hear the noise speed up or slow down with the car. The tires were a little underinflated, so I aired them up to the needed pressure.

Could it be an axle problem? What areas should I start with? Thanks in advance.

this could deal with how your suspension is moving, ive heard of this before in a friend of mines car and the thud he was hearing ended up being something in the suspension assembly being loose, it was a simple tightening of a bolt.

 

make sure frt radius rods nuts are tight and bushings are ok,,

 

My rotors were doing that for a little while, they were shot. I don't know but you may wanna check them. Does it make noise when you turn at low speeds? If so, check the axle boot.

 

It doesn't really matter if I'm am going straight or turning. It definitely does it while driving straight line. I'll check the front suspension components to make sure they're all snug. Thanks.
