Eibach Springs and clunk sound

[PhillipRumans]

I had the eibach springs put on my car about two months ago and everything has been good most of the time. Now though for the last 3 weeks I seem to sometimes feel and hear a thunk when I go over some bumps in the road (not over speed bumps). It is a muffled thunk sound. There are no handling issues with this. I did try pushing down on the right front fender to see if I could duplicate the sound and got nothing. However when I pulled up on the fender and then pushed down, I could hear and feel a thunk which seemed to be in the upper right fender well area. I am not mechanically inclined and was looking for any ideas before I take it in to be looked at. Thanks in advance.

By the way it is an 08 Altima Coupe 3.5 SE with 11,5k miles and still has the 17 wheels on the car. The eibachs were the only mod

did you replace your strut mount bushings?>

also, check your front sway bar bushings they may be on their last leg. this cause noise as well.

it most likely is the strut mount bushings. does it do the sound when you panic brake.?

Did you have your car looked at yet? I wonder if the spring is seated properly on that side.
