Hey guys, lately I've been having some thumping sounds going over even the slightest uneven roads. I lifted the front end recently and gave the wheels a wiggle in all directions and they are stiff as can be. I have less than 15-30k miles on most front end parts. Looked at the control arm bushings, sway bar end links, inner ball joints, tie rods ends. Good shape and no wiggle. All in one piece with no cracks on bushings. I have about 30k on the Koni adjustable shocks and Eibach springs including the strut mounts. I was planning on jacking the whole thing up soon to really get deep under there and do a detailed check up. Is there anything else I can look at that can be causing this? I tried checking the motor mounts to rev the engine while holding the brake to see if I can replicate that sound but it sounded and felt normal. Let me know if you guys have any ideas what I can look for. Is it possible the shocks are done for already? I did the classic shock bounce test they taught us in tech school many years ago lol, but it feels very stiff with little to no bounce. Thanks.
