This video is part 4 of a 4 part series.
Part 1 is here! Front hub bearings, inner and outer tie rods, fixed an oil leak, and replaced front shocks. https://youtu.be/m-E6-6TLWhM
Part 2 is here! We moved around back to replace the rear shocks, we cracked open the rear axle cover for inspection and cleaning, plus a bonus freebie repair that could save someone's life. https://youtu.be/DyL5vAulC4w
Part 3 we break into the a/c system and found that metal chunks have been circulating through the system. https://youtu.be/085RX6kdxM8
