I have had a rattle noise for a few weeks now so today I chased it down. it made the noise when starting out from a stop sounded like a sheild under the car. The problem was the air cleaner support bracket on the back of the air cleaner housing where it bolts to the exaust manifold worked loose causing the rattle from the loose braket. Tightened the bolt and all is good again. Just thought I would share this info incase someone out there has rattles they are chasing.

 

Gee..... You are "Lucky" (pun intended) several guys have that rattle and that bracket has been rusted away.....

 

I just installed rear shocks on my '06 hhr. Can anyone tell methe torque specs on those bolts. I set the top bolt at 60 snd the lower bolt at 80 ft lbs.

 

Service manual says 66 ft lb on the upper bolts, and 92 ft lb on the lower bolts. You can round down to 65 ft lbs and 90 ft lbs respectively without causing issues.
