Big questions i have here are...do u have space to do this work and another vehicle incase its not done in the alloted time. I had more of these front ends torn down and apart than i care to think about and everytime, one thing or another, it was a major PITA. While the actual work isnt bad its the unforseen problems like mentioned above...rusted bolts, stuck/rusted parts, broken bolts, etc...
FWIW, that price doesnt sound to terribly bad. If i were to do all this, i would just drop the entire axle out and service it out of the truck and install it as one. Its far easier doing it this way but just removing it can be a challange if u dont have the tools or experience. I did my dads this way, mainly becuase i needed to replace the coil buckets on the frame (95 F150) but doing it was so much easier and allowed me to service the front axle, replace the pivot bushings, ball joints etc...without having to be crammed under the truck.
To do this job ur gunna need some heavy duty jack stands, at least two floor jacks (i use a motorcycle jack), ball joint press, hub sucket, pickle fork, torch, large sockets, some type of impact (pnumatic or cordless), spindle removal tool, slide hammer...just to name a few...
Have u verfied the actually parts are indeed worn?
