Thanks RJ, dagg gum autocorrect!!!

 

Okay so I took my recorded video to my mechanic. The rattle ended up being the sway bar links that I put on weren't torqued high enough and they were loose, they tightened them up for free. The old ones were bad though because they made the same rattle after i got my sway bar bushings done. Thanks for the help. I'm just so relieved that rattle is gone and no more money had to be spent. I still hear a tiny bit of noise from the suspension but it doesn't sound like a loose thing.

 

Great case closed!! Good news!

 

My car is sounding the same as it did before I had the sway bar bushings fixed. Going over any sizeable bump just can hear everything. It sounds like the swaybar bushings again that were fixed a month ago. It's frustrating because my crappy Sunfire that was rusty and beat up sounded better than this car does going over bumps. I'm regretting getting this car it just makes too much front suspension noise and there doesn't seem to be any way of permanently fixing it.

 

Any thought given to rechecking all of your nuts & bolts? Or the fit of the sway bar bushings. Or the hubs. or the strut bearings. or the tie rod ends. among other things.

Here's part of the diagnostic TSB:
CONDITION #2 (CHEVROLET COBALT, HHR AND PONTIAC G5 ONLY)

Some customers may comment on a clunk or thump noise coming from the front suspension while driving over
rough road surfaces. This noise will typically occur when the front suspension is returning to the upward
position after a hard downward stroke, such as after driving through a large rut or pothole.

CAUSE #2

This condition may be caused by the jounce bumper slamming into the upper spring seat because it is not
retained in the correct up position. The jounce bumper loses position due to oil being deposited onto its
retention fingers. The oil is from the strut leaking.

CORRECTION #2

Inspect the front strut(s) for evidence of oil. The leak may be slight but will still cause the concern. If oil is
present, replace the affected strut, jounce bumper and dust boot (shield). Before reassembling the strut
assembly, glue the new jounce bumper and new dust boot (shield) to the upper spring seat using the steps listed
below. To further confirm this concern, the shield/bumper will easily slide up and down the strut shaft.


It come right after "If the steering column is not identified as the source of the rattle/knocking in the above test, continue to diagnose the vehicle according to the diagnostics in SI."

 

The sound had just come back. I'll have to check it out down there. I have the greasable zerks in my new bushings there's a start.
