putting susp lift in, what else to replace?

[aggiedave98]

I'm putting a 3" fabtech suspension lift on my '89 suburban (1/2ton 2wd w/ 115k miles). Originally I was going to replace everything on the front end (tie rod ends, pittman arm, idler arm, etc.) however, now I'm wondering if I can do things like pittman arm and idler arm later and just go for the tie rod ends and ball joints now. What do you think, should I just go for it?

Thanks!
