I have a '98 Taco V6 4x4 that I've had for less than a week.
Well today I noticed 2 drops of oil under the truck every time I had it parked for a half hour or more. There was always 2 drops a bit bigger than a quarter. I looked under the truck and noticed that the transfer case was covered in oil. *SEE PICS BELOW*
It seems to cover the lower section of the transfer case and partially back towards where it joins the transmission. It's a dark oil as you can see. I have the trucked park now so I don't do any damage just in case the oil is low. However, it's shifting into 4WD and driving fine, and also driving in 2wd fine (aside from some sputtering when under load at 3K+ which is a suspected bad O2 sensor).
Does any one have any opinions as to what my trouble is? Seal, multiple seals? I'm hoping it's not the whole transfer case being screwed! If it's the seals, what kind of labor time is involved in getting them replaced as well as approximate cost of the seals.
On a another related note, does anyone know where I can download/buy a '98 Taco service manual?
Thanks in advance for any help/input!
