hi guys i've got a 03 sunfire i just purchased that makes a thump noise every time when decelerating quickly or speeding up quickly and i simply am running out of ideas on how to fix it. this noise seems to be coming from the front of the vehicle beyond that i cant find anything else wrong with it other than the parts i just replaced

so far the car has a new rack and pinion, inner and outer tie rod ends, new intermediate shaft, wheel bearings , lower control arms, brakes, sway bar links, both passenger side motor mounts , and all 4 quick struts.

noise isnt coming from the engine being torqued i do know that.

is there any form sub-frame bushings on these cars like the gm mid size cars of this era? didn't look real close ,but doesn't look like the same sorta droppable front subframe.

only other basic possibility ive thought of is sway bar bushings being bad (didnt check ,but didnt feel super loose when replacing the links).

plz help have literally almost exhausted every option this clunk is going to drive me nuts.

 

still nothing cmon guys

 

still not completely fixed but i fixed a few issues (spare tire jack was clunking in the trunk due to a previous owners stupidity). front subframe assembly where bolted to the unibody was a little loose (im assuming due to the dumb *** shop i allowed to install the rack and pinion). still making plenty of noises, squeaks in sharp turns (cheap monroe quick struts), also make a slight clunking here and there when abruptly stopping or slowing down) but i give its just a cheap econobox car i guess.

i checked the sway bar bushings they are tight, i rechecked the motor mounts, the two that aren't new feel tight. links are new so on.
