Bcross82 Ok I have been working on my hhr due to a bad mechanic... He installed the wrong sway bar on vehicle and linkage Slt. I also noticed after getting all bolts out except for the rear bracket bolts. That he installed those in upside down. Which has created a huge issue on removing them. I can't fit a 15 mm wrench around the bolt head due to frame and the shaft goes to the top under the metal lip. How he got it on and tight is beyond me.
