hey what up, got a question for all you mazda freaks out there....lol ok my we i have been hearing this thud ever once in a while when i take off from a dead stop, kinda sounds like its coming from somewhere in the back of the car, anyone else heard this before. I have also read in forums that this could be a ABS test the car does



2004 Rx-8 130,000 miles

 

If it only happens once when you first start out, then yes, it is likely your ABS. If it happens repeatedly, it is likely something else.

 

Yeah it happens repeatedly

 

I have also replaced the shocks and springs back there, maybe they settled in and I need to go back in there and tighten some more
