Before you start replacing any parts just go over your existing stuff to make sure they are ok. Swapping inner/outter tie rods is still a breeze even after you already swapped the new steering rack. For outter tie rods, jack the ront end of the car up and place your hands at the 3 and 9 o'clock positions and try to wiggle the wheel, you can also determine if the balljoints are bad this way tool, but make sure you give them a closer inspection before jumping to conclusions. Make sure the steering wheel is locked in place so you dont associate the actual turning of the wheel as "play". For the Inner tie rods, leave the car jacked up, and grap ahold of the inner rod itself. Try to pull it side to side (towards the wheel and back towards the middle of the rack. If you sense any movement/play then replace. If you arent experiencing any bumpsteer now then you can wait for the bumpsteer kit. Personally I would go with UPR's kit since it is cheaper....BUT, the part quality is sup-par. So, you can save money on the cheaper brand and then buy a new "joint" for it from a seperate company which will make it even better than any of the other expensive performance brands. PM Handz or look through his current threads, he replaced part of his UPR bumpsteer kit with new joints from an off-roading company and he claims that it made a night and day difference....I will do this sometime in the future also.
