2010 Ford Focus 4-dr, popping noise from front end

I've been waiting for something to happen...
I now drive 90 miles to work, 4 days a week; or 720 miles a week (since Oct last year). Just today, I hit the brakes kind of hard and heard a "pop" or a clunking. I also hear it now going over pot holes (which are almost unavoidable in SE Michigan in the spring).
It's been my experience that this means a ball-joint, but I thought I'd ask you experts first. What do you think? And whatever your answer is, how do I test your theory(s)? Thanks in advance.

Does the noise increase when you turn one direction or the other?

How many miles on the vehicle ?
Could be a CV (constant velocity) joint problem.

Michigan = salt and salt = rust. Check the top bearing for the McPherson struts (under hood). They have a tendency to rust and begin binding. They will pop loudly when the strut compresses or extends such as hitting a pothole. Put about 2 tablespoons of thin oil on the bearing ball where strut rod comes through. Bounce the car to spread oil and then test drive and see if popping noise changes or goes away.
If this helps the popping noise, then consider replacing the top strut bearings.
Good luck!

Clunk at up/down points towards sway bar bushings. Start there. Next would be control arm bushings.

Thanks for the responses. I haven't heard any difference in noise between turns and I just hit 72K miles. I'll check the strut tops and sway and control bar ends and get back. Thanks again; you guys haved saved me thousands of dollars in the past, and I'm not exaggerating!

Blocks in front and back of the 3 tires you are not working on ( I use old bricks ) . Put the transmission in park ( if automatic ) and the emergency brake on .

Safely jack up one front corner of the car .. Safely support ( jack stand ) that corner of the car .

You may or may not need to remove the wheel .

Visually examine all the rubber suspension components for wear / cracking . Carefully try to move each of the associated parts . May need to use a pry bar .

Look for excessive movement . Also look for rust damage and physical damage / bent parts .

Do you really have the capability to DIY ?

If not , try to ask around and find a mechanic that is qualified and will not try to sell you the moon and stars .

God bless

Thanks wyr! I actually did exactly that last week! The visual inspections yielded nothing blaring. But the grab and wobble doesn't tell me as much because I'm not sure how much each joint *should* give. Since I'm at the end of my knowledge-leash, I think I'll pop in on an old mechanic friend who owes me. Thanks for the feedback.
