Took the 63 Ambassador out driving to a local car show in nice weather this weekend. Noticed while driving at slow neighborhood speeds, over bumps, dips etc. the left drivers side front has a clunking crunching sound. What should I look for? 
Thinking might be bushings etc. ? Better to have a shop take a look? 

Stock suspension, brakes, past receipts show upper lower control arm bushings replaced within past 4 years. Have TSM, looking for thoughts, suggestions..
Thank you!

Could be almost anything in the front wheel area.
Your looking for something loose or broken. Jack up the wheel and give it a good shake and twist. If that does not find something, remove the wheel, inspect everything and then use a piece of hardwood to pry things about to see if you find something loose or broken.
If it's not staring you in the face after this, take it to the garage.

My American was like that when I lost an inner/upper bushing. 
itI replaced it, then the other side went.  I think the replacement piece being good simply put more force on the opposite side and made it fail faster.

Regardless, if it's bushings and bearings I'd just replace all of them at once and get it over with, especially if the frame is solid.  Otherwise they're 50+ year old parts and they'll just keep going one by one.

Well I found something...this is the bushing on the lower drivers side near the crossmember. Laying underneath looking up. This seems like the Pivot Bushing? 
Not sure if this is the exact cause? but this would need replacing unless I'm missing something. Everything else is tight, nothing obvious yet. Hmm..?

If the strut rod bushings are good you've found your problem!!

Generally speaking, it's rarely just one part that wears out. And it's so much trouble to disassemble, you don't want to do this twice... so expect to replace all of the bushings, upper and lower, on both sides, and the ball joint.

The good news is that the upper trunnion on that car will last two lifetimes. Disassemble, clean, lubricate, good to go.

If they were indeed replaced 4 years ago, either bad parts were used -- "NOS" parts should NOT be used when they contain rubber -- old robber is bad rubber -- or installed wrong, or some other problem. 

If you're sure it's just the lower arms, and the ball joints are good, they you can do the lower arm with the spring in place, just insert a piece of 2 x 4 in the upper arm's socket, jack the car.

Note that the strut rod is only "relaxed" when the car is sitting on the ground. If you jack it, adn the spring is extended, there's a lot of tension on the strut rod, and it's hard to get the two bolts out. Likewise on assembly. Last time I did it I got it loosely assembled, lowered the car to the ground, in "running stance", then installed the two bolts (strut to lower arm).

Well turns out the "big" noise problem seems to have been solved, went away with new front shocks! The old ones, wow, ever see a pair so crushed and dented that they are seized up? That's what I took off. I put new NAPA/Monroe and rides much better no noises that I can hear off other than the road. 

This bushing in the picture, should I still replace it? The arm there is still tight, no noise at all when up on the jack stands and move the wheel, or jack the wheel up.

As Tom stated, rarely just one part. Glad you found the big noise, but that bushing looks like it's near end of life and the other side is likely not far behind.
Maybe enjoy the summer, collect parts, and do both sides this fall or winter. Best to do them all if you have the whole front suspension out.

I agree. It's probably due to be replaced, but if no noise or extra movement no hurry either. Just put it on the "need to do sort of soon" list...
