So it seems I have a small leak coming from the steering gear box. Sorry if this seems a little stupid but the center diff is in the transmission and and rear diff is exposed correct? Every where I read says make sure the gear ratios are the same. (Mine being 4.4441 or something to thay effect) does this affect the steering rack or are these pretty interchangeable? Having a hard time placing a wagon rack however I can get a boat load of impreza ones.
