1990legacywagon

Thanks for the help guys it was the stub axle coming out of the front diff had popped out for it all fixed now!

Come on guys im desperate for help

Hey guys, im new here and I've searched around a little and haven't found anything. I just bought a 1990 legacy wagon L it's an automatic with 96,000 miles from my father in law for 400$ he said it ran great but he thought the trans was shot. Well i went and started it and put it in drive and you have to hold it wide open to move, so I put it up on jack stands and the back tires are moving but the front isn't. I put the fwd fuse in and still nothing. I can manually turn the front tires with the car in park so im thinking it may be a sheared roll pin or bad cv axle. But I'm not sure how to tell, any advice guys?? Im completely lost. I checked all fluids and they're all perfect. No lights are on inside except check engine but it's running fine, so if anyone has any idea of what it may be I'd appreciate it thanks!
