Incase anyone still reading. I put the highest end moog everything on my k2500 sub 99, ball joints, tie rod ends, pitman arms, and all bushings front and back minus lower control arm. That was around 5-6k miles ago. The only part that flat out failed almost right away was the idler arm bracket. I'm glad it did. It got me looking at he center link movement very closely and i noticed the entire center link has a bit of a roll to it. Ive never noticed that before. I've been chasing the steering slop around for years. Seemed no matter what I did I couldn't quite get it gone. I replaced the moog idler arm bracket part with super steer and bought those cognito brackets. That was it for me. My truck tracks great now. In conclusion: For my truck, (and I assume many others)You can replace everything and you will still have that play. The brackets from cognito were the only thing that took care of it. I can't say enough about those things. I do not work for cognito, hahaha.
