okay so heres the deal ,

at very lowwwww speeds, such as 3-10mph i will firmly tap my brake pedal and i get a very loud CLUNK underneath my *** !! i mean its loud !!

i don't know if its the powertrains, brakes, or IDK !!! its odd !

if im rolling in neutral going 3-7 mph i will firmly tap brake and CLUNK!!!!! wtf ... i do it rapidly so i can see wtf it is but i just don't know.

HELP !? LMAOO !

 

majority shows suspension.....it's what mine was as well.

There is nothing mechanical nothing rotating or moving under the drivers seat.

 

see but my clunk is ALLL THE TIME.. firm tap on brake pedal and i get a CLUNK! more on the passenger side but the clunk is so loud and strong i can feel it throughout the whole car !

 

I understand...I fixed mine. Check all of those posts on what to look for so you can do the same. Hopefully it's just the sway bar because it is an easy fix. Check out under the car and trouble shoot. Come along to the Cerritos meet next Saturday if you need some more opinions!

 

will do, glad i work at a shop ! hopefully it has nothing to do with the powertrains and its just the suspension ! :]

 

Try driving around in reverse to see if it goes away. I had a similar problem and it was a small rock stuck between the caliper and rotor.
