Fairtax4me Posted June 18, 2013 Share Posted June 18, 2013 Good fuse? Which fuse? If you mean the black FWD fuse holder on the strut tower, that should be empty. Fuse installed there disables the AWD. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted June 18, 2013 Share Posted June 18, 2013 (edited) what he said . or do you have a CEL on the dash? does your speedo work? if your front speed sensor fails, you will not have power to the rear. or if you have a busted rear axle, very very rare, you will have no power to the rear wheels.

lmdew Posted June 19, 2013 Share Posted June 19, 2013 Or Axle popped out of the rear diff. If they are out by a 1/2" the diff will just spin but no power. Quote Link to comment Share on other sites More sharing options...
Bbob Posted June 19, 2013 Author Share Posted June 19, 2013 No, I checked the main fuse under dash. Axles will pop out? Let me see. Where exactly is the "front speed sensor"? By "busted rear axle" did you mean the main carrier or an axle shaft? Quote Link to comment Share on other sites More sharing options...
ivans imports Posted June 19, 2013 Share Posted June 19, 2013 When you turn both back wheels drive shaft should turn did you check the awd output housing for groves were the slip rings go ? and did you air check the awd in its housing ? can be tested on the bench Quote Link to comment Share on other sites More sharing options...
Bbob Posted June 19, 2013 Author Share Posted June 19, 2013 I'll check the back wheels turning. Every AWD clutch pack I've ever seen had grooves cut into it. I thought since it worked the day before that pressure and vibration pushed them over anyway. When I had the tail cone off I didn't see any chamber that would hold air.

Bbob Posted June 19, 2013 Author Share Posted June 19, 2013 Never lit the CEL No code for transmission Turned both back wheels at once - drive shaft did turn Turned left and right independently with other wheel stopped - drive shaft did turn Quote Link to comment Share on other sites More sharing options...
Bbob Posted June 19, 2013 Author Share Posted June 19, 2013 No code on the "front wheel speed sensor" either Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted June 19, 2013 Share Posted June 19, 2013 find a nice safe piece of wet grass, shift into 1 and punch it. maybe an up hill piece of wet grass. or time to open it up. Quote Link to comment Share on other sites More sharing options...
Bbob Posted June 20, 2013 Author Share Posted June 20, 2013 Left front wheel speed sensor shows continuity. Front wheels pulling all & chirping was the first indicator we had to the problem. Please, what would wet grass tell me? Quote Link to comment Share on other sites More sharing options...
ivans imports Posted June 20, 2013 Share Posted June 20, 2013 when the tailshaft assembly is on bench install clutch pack into its bore then can air check thru the feed port and see if drum piston moves and locks up pack i take the rear trans output shaft and drop it into pack then i can turn clutches and see if is locking Quote Link to comment Share on other sites More sharing options...
