looseness in front end, cause?

had creaking sound in front end that gradually got worse. checked control arm bushings, ball joints - seemed ok. read somewhere on here that sway bars links have sometimes been culprit. removed front sway bar and noise still there. pulled a front strut and found that the strut bearing/mount would rock back and forth some. installed new strut mounts (BAV AUTO brand) and reinstalled sway bar with new links and rubber bushings. car felt great. went for drive the next day of about 60 miles round trip. on way back first slight but gradually getting much more obvious is a looseness in the front. feels just like a bad strut bearing in that its a clunking when you go over a bump or a dip. pulled front wheel - all nuts tight (strut clamp, ball joint, sway bar link, strut top nut,etc.). pulled up on bottom of control arm under spindle. could move it a little up and see a slight flexing in rubber part of strut bearing. doesn't seem like that is the culprit. i used a clamshell style spring compressor and to say it was a PITA is an understatement with the factory sport springs. I did my best to get the spring in place correctly but I'm assuming that there might have been a little settling, hence the reason it felt good at first but then produced a looseness. I used a pry bar on the ball joint and that seemed ok too, no cracking in ball joint boots (inner or outer). could there be a washer missing between the upper spring perch and the mount? this shows two washers:

i had one conical that went onto the top of the strut piston and into the bottom of the perch, then one between the perch and the mount. doesn't seem like there's any place for another.

thoughts?

thanks

I don't think it;s a control arm bushing. came on way too quickly and the problem didn't exist prior to the work done. they aren't that old either. not leaking.

Did you get the car aligned after doing the strut work?

Check your Tie rods. A loose tie rid will make you wander and feel loose, and an alignment won't fix it. In fact, a real company will tell you to fix the tie rod, then come back.
