Hey I got lucky on the dreaded front end clunk / noise problem.
My top strut mount nut was loose. Pull the rubber cover off of the top strut mount. Under is a big nut on the top of your strut rod, if there is a shiny area around the circumference of the nut on the washer it is loose! Bounce the car while watching the nut / stud assembly I could see the clearance in mine.
You do need a big Torx socket (T-50) I think to fix - I had one designed for a 3/8 socket , you will also need a big socket for the nut 26 or 27 mm
I used an 11/16 (guessing at size again-pitiful memory) because I did not have a metric that big.
Anyway put the big socket on the nut and hold it with vice grips from the side. Then insert the T-50 torx bit through the opening on the big socket and turn ratchet COUNTER-CLOCKWISE (as if you were loosening it) this causes the strut rod to rotate up into the nut and tighten itself.
Remove tools bounce and observe- if loose tighten more.
Could also likely perform with an impact wrench on nut itself -i did not try that method.
TA-DA clunk gone- retire to garage fridge for beverage reward of choice!
I hope someone else can get lucky with this fix. -Matt
