Ongoing problem, 2x to dealer, need HELP!!(hyundai techs??)

[BigZach]

Ok, I have an 02 Elantra GT. It currently has 82000 miles.

Ever since it has had about 500 miles, there has been a rattle from the rear driver's side.

I brought it to the dealer 4 years ago, and they changed the right rear strut and endlink. Duh. As soon as I pulled out of the parking lot I hear the rattle. I was soooo mad that it took me 4 years to bring it back.

I brought it back last Thursday because of other problems (mostly wheel bearings and wanted to get the timing belt changed) and figured I'd give it another shot. My car was on their lift for 5 business days waiting for a left rear strut. They change that (part 55351-2d100) and the insulator(part 55310-2d000). I was sooo happy. Of course it was snowing so bad, I pick it up Wednesday, snow all over the roads.

I run over some hard snow, and it makes the same sound. I consider buying a handgun, lol.

But, then it makes another sound at a full stop yesterday. In the same area, like someone's knocking on my rear fender, a very similar sound. So here's my question:

Is there some kind of "emissions crap" like an evap canister in the left rear corner of the car? Something that can fail and rattle????

I've tried taking out the spare tire, the rear seats, everything.
The sound is definately coming from the outside of the car, because in parking garages it makes the sound over expansion joints and echoes really loud, and usually gets stares from people.
Anybody??

Edit: My car was built on November 23, 2001, which happens to be a Friday.

Yeah i think there is a evap canister back there. I remeber something about the tibs having them moved back. Thats why 97 ones you have to remove your evap can for a CAI. Um.. loose swaybar? Muffler? Muffler that hits on your bumper? Loose gastank heat sheild? hmmm... Maybe you could lube up your supension mounts and links. loose gas tank?

I say 30 mins under the rear of the car banging and hitting everything. Get someone to hop on the rear with the hatch open and see if you can pinpoint the sound.

My accent had that issue and it turned out to be the rear hatch. The bump stops were not long enough causing the hatch to rattle

Where is your jack and spare tire changin stuff located? In my moms old minivan it was in a compartment on the side wall of the rear area and it made funky clunky noise all the time so we shoved a blanket on top of it and viola no more clunky.

Very good idea. Dads blazer did that... why didnt i think of that? -hits head-

Could be the exhaust is hitting the rear sway bar or control arm. If it is a light rattle it could be the heatsheild.

Check those things.

One time my exhaust loosened and was touching the gas tank intermittently. A quick coat hanger tied to teh leafspring mount helped that to stop... and held for 3 years!
