front end noise shock or sway bar links?

[snowmobiler7c]

Im starting to get a noise on my 03 7.3L truck. It happens when hitting bumps i replaced the upper and lower ball joints with moog about 5k miles ago so i doubt it the balljoints and the tie rod ends were nice and tight. ARe the sway bar links known to go bad? I have procomp shocks on the truck they were on it when i bought it. Thinking about swaping them for something better. Anyway to test the sway bar links? how hard are they to replace? thanks

The links are known to pop. Bilsteins would be a nice upgrade to the Procomps..PM me if I can get you prices.
