Saab 9-7x Sporadic Operation of All Wheel Drive System

(13 reports)

The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.

When I'm driving And i turn left or right. The car stops or staggers, or locks up. I can't pinpoint if its all wheel drive problem. I've taken it to shops, yes I've taken to a couple different shops and they think rear differential needs replaced(oil) or transmission. I think its what the problem says up top!! -
Only rear wheels provide traction in snow- 4WD does not automatically engage as it should -
NO traction at all in the snow/ice. It is supposed to engage when the back tires slip...only one of my tires is spinning. -
Car locks up when making slow sharp turns. Feels like engine is going to stop. -
when turning, the tires feel like they're rubbing against something or shaking -
Front tires do not engage in snow or slick conditions -
Had to replace front differential. The transfer case encoder seemed to be the issue after all said and done. Wheels would lock or shutter when turning into a parking space. It felt like a 4wd truck engaged and then suddenly driving on clear asphalt. -
The all Wheel Drive seems to be trying to engage when I stop at a Traffic Light that is on a slightly downward slope. I feel a slight nudge click several times. I this the speed sensor, transfer case, transmission. I am ready to do a Transmission Fluid / Filter change and though maybe it is a Hydraulic thing. The vehicle runs great other than that. My tires all match and shift great moving. -
