I climbed under the truck to grease the front end and I realized that I have diff fluid seeping out of the passenger side. The outer seal was replaced lease then 10k miles ago.

I looked in the tech folder and did a quick search and didn't see anything. My question is this something I can do myself or is it best to leave it to someone else?

 

did you check the diff vent and make sure it was clear. I know down here in Gawga the dirt dobbers like to build nests in any hole they can find and will plug up a vent. just a thought

 

I will do that. I never thought about that as an issue! When i spun the truck and buried it up to the hubs in mud in July, mud got in places I never thought was possible!

 

No one has replaced the inner axle seals on their front diff?

Bump!

 

Yea I have a few. You have to pull the axle out to replace it. If you do that you have to replace the outer one along with it. They have an updated ones to fit better. They normally just hang there until someone replaces it with the updated one.

 

got this from a 7.3 thread. might get you started

You don't have to reshim anything since your not changing any of the gears. Removing the 2 U-clamps from each side of the gear and a little prying will pull the gear out after you pull the axles out of course. You'll need a bar or pipe of some sort to bang the seals into the pumpkin from the outter axle opening. In front of the seal is a cone shaped plastic piece that will help direct the axle into the seal when you reinsert it. I pushed mine out with the seal (cuz i didn't know it was there) but it doesnt have any effect on sealing and if you do knock it out chances are its broke and cant go back in. I didn't have a problem at all getting the axle thru the seal without it anyway. Knock the seals in gently into each side from the inside of the pumpkin. I used a small ball peen hammer and it worked fine. Reinstall the gear, u-bolts, etc and close that up. I'm assuming you know how to tear down the wheel/hub assemblies?

I did see some special tools mentioned in another thread but no details




here's another thread with some pics
