You won't be able to feel the benefits of the new bushings if the steering system is all sloppy. Now is the best time, budget permitting, to replace all the wearable parts like the centerlink, tie rods and idler arm. The centerlink and idler arm are best installed at the same time. Loosely install the idler arm and then attach the center link to the steering arm then to the idler arm, then come back and tighten the idler arm. There is a large protrusion on the lower crossmember that makes it pretty difficult to install the centerlink with the idler arm tight.
