I just put Rancho Quicklift Loaded struts and a new set of 33" tires-upped from 31's. This seems to have accentuated the play I feel in the front end when hitting bumps. My alignment guy said the lower ball joints are going bad. What other parts should I look at replacing in addition to the lower BJ's to tighten up the front end? Truck is 4wd and has 90k miles.

 

Lower ball joints for sure, I'd inspect everything else, but maybe tie rods [inner and outer] upper arms
