    So I'll be fixing my 91 ford bronco full size tomorrow afternoon and thought you guys might have some advice. It won't start, and it's not the battery or solenoid, leading me to believe it;s the starter. I turn the key and get a single click.

    *In the days leading up to this issue, it was making sort of a higher pitched whirling noise when I'd first start it. I'm not sure if this is an indicator of another problem.*

    As always, the help is much appreciated, as I am far from being a mechanic.

    generally, just a click means the starter is not getting full power. Check for corroded power lines at the starter

    If the starter was growling during use it could be the bushings are shot. When bushings are worn the commutator shaft can c o c k sideways and the armature can short internally. If your battery seems to be draining as well from poor starting, all the more then, it seems to be leaning to an internal short due to worn bushings.

    You should be able to rule out battery or solenoid by checking the voltage at the starter during cranking. Should closely match battery voltage. VOM between starter post and ground. If much lower than battery voltage suspect corroded or dirty contacts or bad cable between batt and starter.
