I’ve got a leak coming from the seal between the front transfer case and the front differential. Where can I get the seal between them and is the oil in the front transfer case shared with the front diff, because I can’t find a fill plug for the front transfer case. Pictures are attached below. On a side note, does anyone know where I can get the brake light switch for the 590, I’m 16 and have my tractor driving test in 2 days and the switch has gone bad. Thanks
