I have a '94 Bronco that on occasion the left front hub (yes it is an auto-locker, and I have been too darn lazy to change them) locks on it's own! This usually happens after backing out of a parking space and then turning hard to either direction. Since the T/C is not engaged the hub just ratchets until I slow to a stop the next time and then suddenly engages with a big thud! My question is, is my only problem the auto-locking hubs, or is there something else going on? Thanks in advance for your imput.
