1988 bronco ii Front tires get hot?

You mean like smoking hot? If so then the brake calipers are probabbly not releasing all the way. This will cause the brake pads to drag on the rotors and create tons of heat buildup. This fix for this is to replace the calipers and brake pad and check\replace the rotors bc it probably warped em. Another thing might be the front bearings are going bad and might need to be replaced. This would mean the bearings will need to be replaced. Hard to say without seeing it in person. Also if the wheels dont have the right amount of toe-in and camber if could cause the front wheels to built up heat from them being slightly skidding. this would entail getting an allignment. I hope one of these is what is wrong with your vehicle. Good luck.
