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!!
Mine was fine when i ought used. Soon it became a night mare. Locking-up when turning,going backwards or forwards. Clunking, wining when slowing down. So I looked on line and many others have this problem. I changed the Motor on the side of the transfer case and the problem went away for about 3 weeks. $150.00 for the part and not fixed. The parts store has a control box that is for the AWD system that costs $120.00 and I can't find on the 9-7x where it is. So i disconnected the motor on the transfer case, no more problem. DO NOT let a mechanic tell you the differentials need fixed. This proves to myself and others there is nothing wrong with them. The control box i found where is goes, replaced it and all ok. SAAB would not tell me where it was. They wanted $120.00 per hour to replace with my part.
I traded it off. Some one else can have the next trouble now. I can say i liked the truck for every thing else.
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.
