Upper and lower ball joints
not too bad of a job. Take the caliper and rotor off, unbolt the tie rod and unbolt the spindle. Hit the tie rod on the side od the knuckle where the shaft goes though. This will be your best bet of seperating the two from one another. The control arms may need some persuasion (sp) to seperate from the spindle so have a bfh and a pry bar handy. Take the snap ring out on the lower balljoint then hammer it out and press the new one in. Unbolt the upper control arm and bolt the new one onto the truck. Put the spindle back on and everything else you took off. GET an alignment.
upper ball joints pretty easy. you have to get new uca im pretty sure. you wanna get camber bolts while your at it. a tip is to soak all the bolts with wd40 or something a few night before and keep soaking them every night cuz mine were a PIA
