Early Bronco

This is my first AWD car so I’m not familiar with some of these acronyms.

I want to make sure I’m changing the right fluids. These are the ones I’m aware of:

  • Oil – follow the Oil Life Indicator
  • Brake – every 3 years
  • Coolant – Every 5 years (couldn’t find anything but that’s what my last 2 cars were)
  • Transmission – every 30k miles?
  • RDU – ???
  • PTU – ???

Anything else I’m missing? Any recommended intervals on the PTU and RDU?
