Hey there, so I've had my f350 7.3 for about 5 years now, she's my work truck so I plow and do a lot of towing. Had moog upper and lower ball joints done about 4 years ago seeing I dident know much about trucks then. As I learned more I started doing stuff myself, did sway bar links cause I was getting a bad clunk going over certain bumps and it totally fixed it. Just replaced tie rod ends and shocks but I'm still getting this clunking it seems when the truck rocks side to side, when I leave my driveway apron every morning I can hear it. I did a balljoint check a few times moving the tire up and down to check for play but everything seemed tight, not sure if it could be bushings or what I'm stumped

 

Did you replace the 2 urethane bushings that the sway bar pivots on?

 

I have replaced almost everything in my front end and the last thing left for me is likely spring bushings or depending on year the type of springs installed from factory.

As dkf said the bushings on the bar itself may help I had the wrong size since I bought it and didn't notice until 20k miles later. Even replaced them once. Oops

 

Check the front axle ujoints, my f350 has a clunk and it turned out that the ujoints are bad and the axle shaft is bounching up and down when i hit stuff

 

Also to check the ball joints jack the front end up and remove the tire. Get a pry bar and try to move the ball joints, my joints are tight if i grab the wheel BUT when i tried a pry bar they moved a 1/8"
