In in PA, and my entire car is rusted as a mother. I'd say every bolt underneath that thing in rusted/corroded. As for the mounts, they told me the transmission mount is good. The passenger one was replaced about 3 years ago. Again, I feel this clunk pretty much at the footwall, and just on the driver side.

Not so for the passenger side mount? I ask because my son's can makes a mystery clunk going over bumps and we've checked just about everything. I, probably incorrectly, assumed that if the PMM is ok (and it looks ok to me) then the DMM must be ok. I know the PMMs fail fairly frequently. I replaced my daughters mounts (all three) but only the PMM was broken. DMM was definitely starting to break, but still intact.

So maybe my son's clunk is the transmission mount. Maybe we'll just replace all three of his since they're not expensive when purchased as a group.
In my experience with these cars, motor mounts are accountable for more than 50% of "weird noise" issues.

Got some quotes for this lower control arm replacement. Not only do they recommend both sides, but alignment after as well. Called three shops, they're all $650-$700. This is insanity. What other options do I have?

DIY?

Watch some videos on lower control arm replacements and having an air hammer is pretty awesome. For the price you were quoted I'd buy replacement control arms and an air hammer. But you obviously would need a tank and hose - possibly borrow? I know people with air tools, just not an air hammer.

Each major repair I do I justify buying a new 'big' tool because of the money I save.

Was the clunking noise on passenger side because my 2013 has been check for everything but it sounds like it’s the passenger side strut again
Have you had them check your motor mounts?

If that trans/driver's side motor mount goes, it makes a clunk when you hit bumps, curbs, turns, and accel/decel.

I'm leaning towards replacing the lower control arm on the drivers side. Got an estimate for $280 for that and they recommended an alignment. Does this sound right?
Please tell me what it was in the end I'm dealing with this issue in my 2014 mazda 3.

My '04 has 181K and clunks in the R/F. My struts are worn out and the strut mount on the R/F is shot. Did they change yours when they did the strut? It's possible that is bad. Just a thought.
If it clunks it most likely is the strut mount making the noise. Sometimes the situation will occur that when replacing strut the coil springs are not compressed properly and the mount in relation to strut gets cockeyed and can still get it installed in vehicle. This causes a horizontal preload on the spring which when going over bumps releases and causes a popping. Remedy is pull strut. Compress springs and realign mount strut and spring assembly.
