Can anyone walk me through replacing the rear wheel bearings in a 99 model with ABS? Does it require any special tools? I appreciate your input. Thank you.

The abs shouldn't be a problem unplug and you should be ok. You have to remove the tire and look. Tell me if you have rear wheel disk. Buy the bearing and seal. Auto Zone or Advanced will loan you the tools needed. If you do a lot of work on your car this isn't a major problem. A Haynes manual will give you a picture and step by step guidelines.
