Recently purchased a 1997 LC and took it to get an oil change which I normally would do myself but I took it to Tahoe 4 Wheel Drive so they could check out my diffs too. ...they changed my oil and said both diffs were a little low but fine for now. ...after I got home I noticed this on the left front knuckle. ...it also looks like it's coming out of the axel itself? ...it wasn't like that when I bought it, even had a mechanic take the axel off and inspect it before purchasing. ...wasn't like that when I took it to Tahoe 4x4 either. ...not that they did anything but what could have happened? ...I realize the seals could be bad among other surrounding components but I just drove 10 miles on paved road home.
