when you hit a bump in the road there is a clunk in the front end
clunk in the front end on 2007 Chevrolet HHR
My problem was related to the front strut...it was loose and leaking...
Have the front sway bar checked and you can locate a shop here www.repairpal.com/directory AC Delco and Moog make sway bar repair kits for this
Check the fwd motor mount and if that it good it is more than likely the mid steering shaft.
