I too have had the same symtom since i have had the vx and i completely agree with etl on this,it is not the brakes although it can lead you to think it is cause it happens when you let off the brake to take off,i believe it is in the driveline or rear suspension.I kinda thought that maybe the rear coil springs were getting weak and posibly sliding around a bit when braking and causing this thumping feeling/noise but i am not sure,i kinda quit trying to figure it out a while back and have been just driving it.But you know now that im thinking about this i did notice that it does not do it when temps outside are cold like below freezing especially and it does it alot and thumps much heavier when temps are high.IdunoOriginally Posted by etlsport
