so your in a parking lot or going slow and you turn to almost full lock or close, and something shifts in the front end. like it moves over almost. what can that be? i know someone knows what im talking about. my moms 05 explorer does it though... is it bad?
 
+1 for ball joints

My Notch did this before I replaced the badly worn lower ball joints. Doesn't pop or jump or wiggle around at all, anymore. (The car also would try to change lanes when I pressed on the brakes, even after replacing both front calipers, brake hoses, pads, rotors, and bearings. Stops perfectly straight, now.)

Put 'er up on some jackstands and give them wheels a wiggle up and down. Shouldn't be very much (if any) vertical play at all.
 
see thats the thing. everything points to balljoints except for the test.

the front end does the shift thing
theres some squeaking in the front end that sounds allot like ballkoints.
the front end seems to shift around and its never braked straight.

but when i get it up and move it it stays put.
