There is a lot of play/slop in the IFS front end of our 2007 2500 Suburban. I plan on replacing everything up front with at least OEM, and maybe Cognito/Kryptonite products (if they are worth it) (everything: Upper/lower ball joints and bushings, tie rods, center link, idler arm, pitman arm, sway bar endlinks, steering damper) including the steering box. I have heard of a lot of mixed reviews with reman steering boxes. Does anyone here have any experience with redhead or bluetop boxes? and aftermarket/beefier front end components? GM IFS has always been an issue with GMT800 and GMT900 series trucks. Trying to pre-plan all this before I roll around on the garage floor and inevitably start breaking things. Thanks.
