I leveled my 2004 screw with a 2.5 HBS kit and my sway bar end links won't stay tight and gonna need new tires soon and I'm going with 305/65r18s. Will I need I replace the end links? What should I do before I get tires to solve the problem?

 

They're probably broken inside the sleeve, just replace them they're pretty cheap.

 

Does advanced or somewhere like that carry them or are there better aftermarket ones I can order?

 

Advance, autozone, oriely's, napa, etc. you can find them at pretty much any auto store, depending on your location though some may not keep them in stock, but you can always check online before hand. As for brands energy suspension and moog always seem to be good choices.
