I have a clunk in the front end on the throttle it seems to be less prevalent coasting over bumps you hear it more. At 110-120+ KMH on the throttle the steering wheel is solid but if you let off the gas it starts shaking letting it slow itself back down to 100 it goes away. There is no issue with steering up to that in speed. To me its weird because simply being on the gas makes it go away let off it shakes. I replaced the motor mount with a solid one as stock broke but it did it before it was replaced.

 

Could be loose control arm bushings. Do you hear anything shifting when you do a low speed hard stop?

 

The odd time it feels like something settles in to place stop hard or giving it gas. If I am coasting and engage cruise control it will do it too.

 

Check on the bushings, they can definitely cause clunks over bumps and slight shaking like you described.

 

Control arm bushings made my car shake under braking.
