I have a 1994 Ford Explorer that is having issues with the anti-lock brake system.?

Only when im msking a right hand turn the abs goes off til I straiten out the wheels.....? I have since taken out the abs fuse so It didnt cause more damage to the abs system....Also my 4wd no longer engages....The light comes on and when 4 low is activated the rear tires still go in low but nothing is happening with the front tires...Please Help!|||Wheel bearing is just starting to go. You'll need to have it scanned to find out which one. Just feeling it won't do it, you'll have to scan it.
