I recently had a shop quote me roughly 1200.00 (parts & labor) to replace the upper and lower ball joints, idler arm, pitman arm, adding knock-outs, and finally an alingment. I am in complete agreement with all of this needing to be replaced as the truck has about 170,000 miles on it. What I was wondering was if there was some reason that they would not recommend the inner/outer tie rods, and center link not be replaced? Anyone know or should I tell them to replace them also while their at it? Thanks for all the help. John
