Hello, my new toy is driving me up the walls! I replaced the radius arm bushings on sunday with napa polyurethane bushings (the old ones were loooong goone!!!). Before the replacement the truck pulled to the right with a slight shake at 55 mph. Now, after the replacement, and rotation of tires, it pulls hard to THE RIGHT! The shake is much more severe now, too. The tie rods apear in good shape (nice and tight), and the brakes do not drag. The outside of the right front tire was worn much more than the rest of the tires, and I can push the spindle in and out a little, too. The wheel bearings are tight as well. Could this be the symptoms of a bad set of ball joints? I think this is a little weird on a truck with 80,000 street miles. Is this a common problem with Lightnings, and if so why? I am suprised because my 91 F-150 has over 120k on it and it is still nice and tight. Any advice would be greatly appreciated.
Well, I am sure that the problem doesn't lie in the steering box or worn tie rods, because both are super tight. My bad, I meant to say that the truck now pulls to the left, not right. Is the caster/camber adjustable on these trucks? The only thing I see that would affect it is the ball joints ( correct me if I am wrong).... How much play in them is acceptable?

Well, I went through the truck, and this is what I found... The drivers side lower ball joint was bad; replaced, the passenger side wheelbearing had no preload; tightened, all 4 tires were in need of balancing, 2 worn out of round. After this, it rides really smooth, with a very slight pull to the right. I will check alignment this weekend. Thanks for the advice!
