What transfer case do I have in my 1989 Bronco?

How do you change the fluid in the transfer case on your 1989 Ford full-size Bronco 4.9L and what fluid should you use?

• Answer:

  I used a 1/2 gallon pickle jar and a hand vacume pump. Install two fittings in the lid of the jar and attach the hose from the vacume pump to one fitting. Attach a second hose to the other fitting and put it into the transfer case through the fill hole. When you pump the vacume handle it will create a vacume in the pickle jar and suck out the fluid. It helps if the fluid is warm, and you have to keep moving the hose around. I have used this setup to remove all types of fluids.
