Special tools aren't required- just more time than usual for a brake job (I quote this type of job at 8 hrs when doing it on the street by myself). The brake assy's are inside the hubs that support the drive wheels. There are a series of nuts on the front of the rear assy (behind the upright) that need to be removed as well as bolts inside the wheel well (3/4" head). Once these fasteners are removed the hub & wheel assy's slide out w/ the brake assy's attatched. There are covers on top of the hubs that give access to the brake line connections which need to be disconnected first before removing the hubs

Make sure the lift is supported properly before removing the wheels & be sure to replace the axle seal & O-ring in the differential support bearing assy. IMHO- getting the bearing support out of it's housing is the most frustrating part of the job- be ready to sacrifice a flat head screwdriver or 2- bending the tip at a right angle to get under the lip works.

Be prepared to loose a good bit of ATF when the hubs are pulled & even more when the bearing supports are removed. Fill w/ the latest Dextron when the job's complete & you should be in good shape.
