      I just did all four of mine on my '03 Sport Trac. I replace the upper control arms and the lower ball joints with Raybestos professional grade parts.

      The lower ball joints can be pressed out and new ones in, the uppers need the complete control arm replaced and come with the ball joints. The passenger side UCA is a two piece design, you have to choices with this UCA

      1. You can replace the complete UCA with a one piece design replacement thet comes with new bushings. (I went this route)

      2. You can replace just the lower piece of the UCA if your bushings look o.k..

      Most of the replacement UCA are reusable and just replace the ball joints in those UCA.

      Here's the link for the lowers, no you don't have to remove the axleshaft.

      I got an electric impact gun from Harbor Freight and it was a life saver, it's not hard to do them without it but it made a world of difference. I also bought the ball joint/ u-joint tool kit form there as well.

      You don't have to remove the hub bearing assemblies to do the do either lower or upper ball joints, it helps and makes it easier to do the job but you don't have to.

      To remove the hub assemblies is pretty easy to do, it's only three 15mm bolts the hardest part is breaking them free then just take a hammer to seperate the hub from the spindle, easy, trust me I've done it enough.

      With the truck on the ground loosen the axle shaft nut to the end of teeth, with a hammer, tap it in to push it back alittle then raise the truck up and put on jack stands.

      Do the steps listed in the links above to remove the upper and or lower ball joints, when you remove the spindle nut and bolt and seperate the spindle from the ball joints just pull out away and pull the axle shaft out.

      That's the Moog list numbers, so if you have a 4wd then you need the 31-32mm set.
