Popping Thunk noise on a 2003 Cavalier Automatic

[Eric Arcand]

well guys im stumped…i replaced almost every known suspension part on the car and im still hearing a loud pop/thunk sound when i break at a moderate speed of 20KMS or faster. A list of parts i have replaced are:
-front and rear complete struts
-lower control arms with balljoints
-outer tie rods
-swaybar endlinks and bushings
-front pads and rotors

im at a loss…as i said its a loud POP! noise when i apply the breaks at a speed greater than 20kms…

here is a video of the noise

Engine mount, transaxle mount, CV joints.
Can you feel the pop say in the steering wheel?

[Eric Arcand]

nah nothing in the steering wheel at all…and also it dosnt clunk or click when i turn so im ruling CV axles out on that part…leaning towards a LF tranny mount

[Its me]

A clunk on acceleration or deceleration is indicative of a bad inner cv joint. Also, vibration above 20 to 30 mph can be a bad inner joint. The pops and clicks on a turn are a bad outer cv joint.

I’m with the others and going to say bad inner CV joint. Especially if it has ever had a impact to the wheel while stopping or a forced stop like hitting a ditch.
