full size bronco should be the 9 inch axle, maybe an 8.8 inch but i think they came out late 80's early 90's. easy to tell the difference, the 8.8 has bolts in the to remove the rear cover and has a more square shape to it, the 9 inch has no rear cover, the front can be removed with the whole third member ( front of rear axle where drive shaft is, the pinion, and all the gears inside axle ) and the 9 inch has a very round shape to it. the 9 inch is the better one to have

RABS stands for Rear Anti-Lock Brake System and is found on all Bronco models except for 93-96 models (they have ABS on all 4 wheel). An anti-skidding sensor on the rear axle sends information whether the rear wheels locks on braking or not to a Control Module which regulates the brake fluid pressure to the rear axle preventing the wheels to lock.
