SOURCE: abs light on
I'm a Ford service adviser. There are many reasons for the
abs warning indicator to come on. The usual cause is from a
faulty speed sensor. Either a wheel speed sensor or the
differential speed sensor. I don't think the light is related to your
vandalism. You might want to take the truck to an auto parts store and
have them read the codes for you. Most auto parts stores will do this
for free.
Good Luck

check your fuses, then check the ABS valve located beside the master cylinder and the wiring to it and finally check your speed sensor, which is located on the transmission on a 2 wheel drive and on the transfer case on a 4 wheel drive. but make sure hat your E-brake is released as it will cause these lites to come on.
SOURCE: ABS brakes grunt, groan noise with brake pedal travel.
Joe it is common for the brakes to moan when they wear down and sometimes they will squeak, try replacing the front pads and lubing the shafts on the calipers install anti squeal on the back of the pads, the ABS device would not cause noise as they are just a ring with a magnet and the reluctor ring spins and the magnet detects the spinning of the reluctor ring, they don't even touch and are stationary in place where they are mounted. There is a possibility that the brake fluid is dirty and could cause the abs motor to groan but you would just have to flush the system, When you don't put your foot in it on the brakes it will make some noise even new, I have a 2008 ford ranger that makes the same noise and the brakes are fine. You will have to adjust your braking habits to stop the noise. You can change the pads and that will help but not for long, be sure when you are operating your brakes press firmly on the pedal until you stop. If the brakes make noise after you let up on the pedal then the caliper parts need to be cleaned and lubed, however it is not a safety issue.

The rear wheel speed sensor is the most common problem on those trucks and will do what you are talking about. It is located at the top of the rear axle in the center. It picks up it's signal from a tone ring on the diff inside! If a tranny input or output sensor is bad then the tranny won't shift properly!
