Hello all! I will preface this by saying my dad and I usually work on our FJ80s together... he is my mentor. I am obviously still in training and need help diagnosing what I think should be fairly obvious to the trained eye. I have a '95 FJ80 with 207k miles on it. Bought it at 185k with a maintenance history that was largely unknown, but the truck was in great condition. Kept up with basic maintenance, replaced the radiator and some hoses, etc. In the last couple of weeks I've noticed some fluid leaking from an odd spot on the center differential... seems to be where the electrical connector comes in (see attached photos). Any idea about what this might be (internal O'rings, etc?). This truck only has a locking center diff so I believe it to be a viscous coupler as well which makes me more concerned about the leaking fluid. Any ideas from you experts? Car shifts into 4 Low just fine, no weird noises or major problems when driving in 4L, I just want to get ahead of a major issue. The photos are taken from the drivers side. In the photo with my hand in the picture, you can see the shiny fluid leaking out right above the bolt. The thing I'm holding has play (i.e. I can wiggle it). Yes, I know it's dirtyyyyy. Thanks in advance!
