teamsmith Posted January 12, 2015 Share Posted January 12, 2015 The parts store offers an 'inner oil seal' on a Dana 35 bolt on axle but when I pull out my axle, I only see the bearing keeper, bearing, and outer oil seal. Is the inner seal up inside the axle or am I reading a spec for a different year model D35? I'm doing the change because I'm leaking diff fluid and want to make sure I'm changing all the seals.

Now I have a clarifying question and, unfortunately, need to reveal my own stupidity. Last month I replaced bearings and outer seal, ignorant of the existence of an inner seal. Stupidly, I installed the outer seal backwards with the taper facing the wrong way. I now have diff fluid leaking. After reading the above linked thread, should the inner seal keep the diff fluid in the diff? Does that mean that maybe I messed up the inner seal or that it's disintegrated since it wasn't on the shaft when I removed it? I would be very happy to learn that I will not need to remove the bearing again. I understand the proper thing to do would be to take the bearing off and flip it but I only have a cold chisel and a hammer and I really don't want to go through that again if I can stop the leak by installing the inner seal.

teamsmith Posted January 14, 2015 Author Share Posted January 14, 2015 I pulled the axle back out and, sure enough, there is a seal just inside where the bearing race sits. I had to improvise for a puller but did use the proper seal driver to beat it into the axle tube. With it all back together I'm no longer leaking gear oil. I would be happier if I didn't suddenly have a low voltage problem. It seems my problems seem to wait until one is solved before the next shows up so I always feel like I'm only one fix away from having a problem free jeep Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 14, 2015 Share Posted January 14, 2015 Quick Tip: Take a couple of minutes to make sure your axle vent tube is clear on both ends. I went through replacing a couple of left axle seals on my old D35 that would weep after the diff oil got hot. The plastic (nylon?) fitting hole was clogged and had to drill it out so the axle could breathe. Link to comment Share on other sites More sharing options...
teamsmith Posted January 14, 2015 Author Share Posted January 14, 2015 Thanks, horn. Can you give a hint where I might find the vent tube? Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 14, 2015 Share Posted January 14, 2015 Here's a pic of it on my old D35. It's the rubber hose on the left side axle tube at the brake line junction going up to a plastic fitting in the frame. Link to comment Share on other sites More sharing options...
teamsmith Posted January 14, 2015 Author Share Posted January 14, 2015 Thanks alot.I'll have a look.I imagine that the leak is due to my messing up the old seal while changing the bearing the first time. Another question: what is that metal rod that connects to the side of the diff? My diff has the little bracket on the bolts and the upper bracket is hanging loose. Is it related to the spare tire holder? Link to comment Share on other sites More sharing options...
