abs scan cost money almost always, its a different kind of scanner. same as a air bag scanner.
any way the last time you had it scanned? what codes did you get? and what did you do so far?
what you can do is jack up each wheel, leave the lugs tight, grab the top of the tire, and push and pull firmly, your looking to feel play in the wheel. if its loose feeling, your hub is bad.
you can also remove the plugs from the hubs, clean them with electrical parts cleaner and then dab some de electrical grease on the plug, and then work the plug off and on a few times to work the grease in.
