Guys, an autologic diagnosis of my abs/brake/dsc 'trifecta' pointed to the transfer case. I haven't yet noticed the tell-tale click, but will check for it and am getting a second opinion [hopefully via DIS] on the cause. Assuming the trifecta cause is not an ABS sending unit at a wheel, given all the info on this 'fault,' I'm tempted to replace the gear in the actuator motor and get the ABS module inspected/rebuilt for $99. I view it almost as preventive steps, a reasonable investment at less than $150 for the parts and ABS module service if you DIY. No way I want spend $3k+ to replace the transfer case, the first shop's 'solution.' Any additional thoughts/guidance?
