It may be something simple. I recently fixed a ford ranger with the same problem. It was old vacuum tubing that was leaking between the headline and wheel actuator.

It may be more than that but it's an easy thing to check.

yo fordblood,

adjsnow's 1990 Bronco does not use the vacuum operated system.

Thanks for participating!
