Specialty tools used:
- Harbor Freight "Four Wheel Drive Ball Joint Service Kit"
- 2" long X 1.25" piece of pipe. (I'm sure that 1.5" diameter would work too)
- 1.5" - 1.75" OD washers (I used four thick ones)
- Small piece of 1/8" thick steel to use as a spacer. I used a thick washer.
- 21mm socket for caliper bolts
- 35mm socket for the axle nut
- 12 point 13mm closed end wrench
- Torque wrench
- might need a pickle fork
- A small box that's strong enough to support the weight of the brake disk and caliper (8" - 12" tall)
- All other required tools are fairly common.
Here's the order of events. (not very useful when taking it apart, but will most likely save some frustration when putting it back together)
1. Remove wheel and clean the working area. A pressure washer works great.
2. Remove the two 21mm caliper bolts and place the brake disk and caliper on the box
3. Remove the speed sensor
4. Remove 3 12 point 13mm bolts, axle nut, unit bearing and axle shaft
5. Remove ball joint cotter pins and castle nuts
6. With the 2" piece of pipe and washers, press out the upper ball joint
7. Press out the upper ball joint
8. Press out the lower ball joint
I could have save a lot of time, by printing out the following and keeping it next to me during the install
