So the clunk has gotten progressively worse. I'm giving an honest thought to maybe blowing up the vehicle or maybe running it into a k-rail.

Anyway, I'm thinking the next step or attempt at a fix is replacing the sway bar bushings. I don't think it's cost prohibitive but how invasive of a project is it? Any information would be helpful.

So have you checked the passenger motor mount yet? If it clunks when you turn right then that's absolutely something you need to look at since it could actually be the engine rocking to the left. While it's good to confirm the things you've recently worked on aren't the problem stop rechecking all of the things you've already checked five times and move on to something else.

The PMM is sitting right there in front of god and everyone. Look for signs of oil leakage below it (black discoloration), any fractures to the rubber portion of the mount, or dry rotting. When I poked my finger into mine it went straight through the rubber it was so dried out.

I appreciate the candor and the advice. I'll definitely check it out. How about that MM under the engine?

I checked the PMM a few weeks ago and it was indeed bad. I could see a slight crack in the top of the rubber as well as oil leakage beneath the unit. I replaced it yesterday. Going into the repair, I thought that this might alleviate my issue with my clunk. Unfortunately, it did not. Clunk is still present.

Have the lower control arms been checked yet?

I think I once did a perfunctory check but nothing more. Is there anything specific I am looking for? Also, would the LCA be in play when I am making a turn because sometimes when the car is stopped and I am turning the wheel to get out or into my parking spot, the pop/ clunk happens.

Any information would be helpful.

It's a long shot but you might try re-torquing the LCA bolts and the front subframe bolts. If it changes the nature of the clunk, you might be on to something.

Also, if it makes the noise when not moving you could get a friend to help you pin down the location from outside the car.

What about inner tie rods? Clunking around in the socket? Mine does this too, it is quite aged though and stock suspension and a lot of things need replaced. I was betting on the rods or the top hats. Mine makes noise from off the line, and when first braking, occasionally around turns. Like the springs are readjusting themselves with load and unload. Just trying to offer a new solution. Is your steering loose/nervous at all? Like even a smudge. Mine is a TINY bit and I diagnosed inner tie rods.

Just read through this entire thread - wow.... Out of curiosity, I didn't see any mention of the front sway bar mounts being checked. If one of those loosened up or a bushing was bad it would make a clunk. Particularly when turning into a drive where one side of the suspension is traveling much more than the other.

Just a thought.
