Got an 06 Honda civic ex four door sedan, automatic trans, about 160k miles, no mods!! Been making a weird pop or clicking noise when drivi g straight and hitting little bumps. I've replaced both axels, inner and outer tie rods, struts, top strut mounts and bearings, checked all the motor mounts, and rack everything is tight and the car drives and runs great, handles great. Just making this noise and it's driving me crazy I cannot figure it out, this is my wife's car and she drives with my daughter alot so I'm trying to make sure its nothing unsafe, please please help me!! Thanks in advanced!
