Hey RC welcome.
Id start with the unit bearings at the front wheels. if its loose its toast and expensive. Next try the track bar.
Does it shake during the thud thud?

well if the sound is under hardish braking then take a look at the end of this thread http://www.naxja.org/forum/showthread.php?t=984055&page=2
