Oh, man!!! This should be the post of the year for "Most ingenious fix!!"

Awesome deal man - who would have thunk eh?

Looking forward to the pictures.

 

 

You got it. I'll try to have the pictures up by Thursday or Friday. It's late and dark now. Then rain/snow for the next few days.

 

Cool!

 

Thanks for the posting 11hhrlt.

Back when I 1st got mine, I had some of those same noises. Took it to the dealer. They looked at it and said they weren't exactly sure what to do but would "try" to fix it. I decided NOT to be a test subject for them.
I went home, popped off the front clip and this is what I did. I laid down some strips of stick on insulation to go between the bumper and the foam cover. It tightened it up enough to eliminate most of those front clunks I'd heard.
I also replaced some of the plastic rivets with nut/bolts. Those were the ones between the wheel well liner and front clip. Too much play where the plastic rivets were attached.
Now I just need to get around to pulling the back bumper and doing the same thing. I have some rubber strips wedged up under there now, but I still get a little clunk back there.

(disregard the yellow circle. It just shows where the ambient temp sensor is )

Cool beans, I'll have to check this area when I replace my headlights next month

 

"I also replaced some of the plastic rivets with nuts and bolts"...

Right, I plan to do that as well. Make the fix more permanent. For now, I'm happy.

 

And thanks very much to members for the thoughtful recognition and input.
It's appreciated.
