I have the 5-10 mph Abs problem. It is 4WABS. No lite on. The speedo has been..working,then not working for some time. I changed the rear sensor. Didn,t do much. The speedo does seem to work more often than it used to. I'm trying to avoid the front sensors as much as I can and check all else that could be a problem. Heres my thing. If the rear end fluid was dirty, would that maybe be a problem that I should look at. The fluid was changed about 5k ago. First time in 100K Miles. I'm thinking this may be a start. I don't want to screw with the front till I have to.
