i was in the shop couple days ago, gettin all the juice changed. when i done most of them cept' the diff's juice, i notice that there's burned juice on the catback piping. but there's right amount of diff fluid in the diff when i drained it. is there a temp fix? im planin to replace it after the rain season

 

do you actually see the seal leaking? if it was full then dont worry about it. just check it a few days after you fill it, then again in a week or so. it could be other things though too.
