Well done, this is on my list in the next few months.
It sounds like there were quite a few tricks you learned in the first pass to hone the time down to under an hour.
Do tell...
Hahaha...I downloaded instructions that seemed pretty clear, but later turned out to be written by an experienced mechanic who took for granted a lot of knowledge and experience on the part of the reader!
In a nutshell...
1. With truck on jackstands, remove wheel.
2. Pry off center cap, remove cotter pin, remove axle nut & washer. Note that you can push the splined axle in an inch or so. If it doesn't slide easily, you might need to tap it out when it's time to remove the hub.
3. Remove the 3 bolts that secure the wheel speed sensor, the brake hose support bracket and the small c-shaped metal shield that covers the toothed ring on the axle. Remove the small shield.
4. Remove the brake caliper; hang it up out of the way with a bungee cord.
5. Remove the cotter pin and nut from the lower ball joint. Here's where things went pear-shaped. The instructions had the glib suggestion to "tap the joint loose." DO NOT hammer on the threaded stud. Not even a little bit, not even with a piece of wood or lead mallet. DO NOT hit it. Don't say I didn't warn you. Do not use a pickle fork. Do not break the dent puller that you've reconfigured to become an impromptu bearing press. DO lift up a bit on the ball joint stud with a floor jack while hammering the living bejeepers out of the SIDE of the lower knuckle (90° to the threaded stud). Beat it long and hard while avoiding all the delicate bits in there. The tapered stud will, at some point, simply pop loose.
6. Repeat this exact procedure with the tie rod.
7. Repeat this exact procedure with the upper ball joint. I used a piece of 2x4 and the floor jack to put upward force on the upper control arm for this. When it releases the whole hub assembly will sort of fall into your hands. If the splined axle doesn't easily slide out of the hub, tap it gently with a wooden block. Stand up, rub your aching back, curse, and relocate to the workbench.
8. Remove the four bolts on the back of the hub holding the bearing to the knuckle.
9. Remove the single bolt holding the brake disc shield and remove the shield.
10. Remove the single Phillips-head screw holding the rotor to the hub.
11. Note the two threaded holes on the rotor in addition to the countersunk one where that screw just came from. These holes are used to drive the rotor off the hub. Using a bolt of a certain size (didn't note the size or pitch) thread into these holes until the bolt bottoms, then drive just a bit more and the rotor lifts right off. Set it aside.
12. Support the knuckle assembly in a big vise or between a couple of 4x4s or something. Use a drift or punch or dull cold chisel or something to drive the bearing assembly out of the knuckle. It takes a bit to start seeing progress but it'll ease on out with no difficulty...just be patient and go around the circumference of the bearing as you drive. I wasn't successful trying to hit the bearing in the center...it's not a question of damaging the bearing (it's junk), but you need more focused force to drive the thing out.
13. Use emery cloth to dress up the inside of the hub sleeve; it will be a bit rusty.
14. Grease the outside of the new bearing hub and the inside of the hub sleeve. Insert the bearing hub. You won't need to hammer anything as it presses right in. Note that the bolt holes align only one way.
15. Replace the brake rotor (yes, it's held on with only one small screw).
16. Replace the brake disc shield.
17. Grease the tapers where the two ball joints and tie rod will be. Grease the axle splines & inside of bearing hub where splines will slide in.
18. Slide the lower ball joint in place and thread the bolt on to hold it in place.
19. Use the floor jack to raise the suspension a bit, fitting the upper ball joint together.
20. Reassemble the tie rod connection.
21. Tighten the two ball joints and the tie rod end and torque to spec; replace cotter pins.
22. Replace brake caliper & tighten the two bolts to spec.
23. Replace the small c-shaped shield, brake hose holder bracket and wheel sensor (3 bolts total).
24. Replace the axle washer & nut, torque to spec & replace the cotter pin.
25. Lightly grease the metal cap and tap it carefully into place.
26. Install the wheel. Done.
