clunking sound???

[MN2010MZ3]

So i noticed that im starting to hear a clunk/popping sound when i roll over a speed bump or hit a driveway uneven in the rear of my car. I did install roadmagnet springs about 4/5 months ago,i have no problems with performance or anything but its starting to get annoying so i though id ask here before i do anything. Any help would be GREAT! thanks.

Most likely sway bar hitting the sub-frame caused by the lowering. Adjustable endlinks would be the solution if that is the problem.

I'd agree with the above, except I wouldn't have thought it would take so long to notice, or is it not a new thing. Otherwise, double check everything you unbolted when doing the spring install. When my suspension was installed we had one part that was just a bit loose when put back together and that cause a clunking that I would describe as similar, tightened it up and went away. It's probably an easy fix once you find it, adjustable end links would be a solution that wouldn't be a waste even if it didn't fix the problem.

Check the bushings on the sway mounts too. My Hotchkis FSB clunks, because the bushings are a little off (it's a design flaw, they're too big). Nothing wrong with it persay, but it does make a noise.

Broken endlinks can cause a clunk as well. Been there.
