About to attempt to change out all ball joints and tie rod ends as well as idler arm/bracket and pitman arm. Probably going to order my stuff from rockauto. Need to know what size lower ball joint to order. 45.79 mm or 47.89 mm. I have a 1998 2 door tahoe with the 5.7L. Its 4wd with the auto/push button set up. Everything is stock. Thanks for the help!

PS Curious if I should change out the center link that attaches to pitman/idler arms and tie rod ends. Not sure if this parts tends to wear out? Any ideas.
