What is the name of that seal and how should I go about fixing it?
I don't know the name of every part (as you can tell) but i've replaced fuel pumps, rotors and pads, and window regulators. I'm kind of handy but I'm not sure if this project is over my head. Here is a picture of my leak  |
this looks like the front gear box axle seal.
the gear oil to use is 80-90wt GL5 ..did you replace this oil lately or did someone else ? this gear oil is a heavy oil...could be engine oil spilled down from fill spout ..check the gear box oil level should be 1/2 inch below the fill hole when cold...when hot at the top of fill hole.....
some times these will weep when temps change then stop leaking...
