I would also like to suggest this as a possible cause of your concern. This is taken from our "sticky" file that ChevyMgr maintains regarding TSB's that may be of concern to HHR owners.
I would suggest that if replacing the easy or cheap items do not solve your complaint this should be considered.......

Condition
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
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
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.
1. Clean the surface area of the upper spring seat using fine sandpaper.
2. Apply a light coat of *3M™ Automotive Adhesion Promoter, P/N 06396 or equivalent, to the top of the dust boot (shield) on the inside edge and to the top of the bumper. Allow to dry 10 minutes.
3. Glue the bumper to the inside of the dust boot (shield) as shown. Use *3M™ Duramix™ Super Fast Adhesive, P/N 04747 or equivalent. Allow to cure thoroughly 5-10 minutes at room temperature.
4. Apply a light coat of *3M™ Automotive Adhesion Promoter, P/N 06396 or equivalent, to the top of the dust boot (shield) and to the upper spring seat surface. Allow to dry 10 minutes.
5. Glue the dust boot (shield) to the upper spring seat as shown using the above recommended adhesive. Allow to cure thoroughly.
