How to replace transmission axel seal
This is for a 98 Civic LX with manual transmission…
About a week or so ago, I replaced both axels due to CV boot issues. I just noticed that I am leaking fluid from the passenger side transmission seal. In the back of my mind I “knew” those probably should be replaced when I did my axels, but I didn’t. I assume that a combo of age and me removing/reinstalling the axels caused the leak.
Anyhow, is it as simple as…
1. Drain transmission
2. Remove axel
3. Note how deep the old seal is.
4. Pull out old seal using some type of seal puller.
5. Clean up surface on transmission.
6. Pound in new seal (make sure it goes in perfectly straight) with rubber mallet to proper depth
7. Clean up surface on axel, and lightly grease axel stub
8. Reinstall axel
9. Replace fluid
I know all of the tricks on getting axel out, replacing fluid, etc. But is there any special things that I need to do for this seal? Is the seal supposed to have any other sealant applied prior to installing it? Or is it just rubber to metal? If just rubber to metal, do you lightly lubricate it before pounding it in? Or just do it dry?
Since one side went, and since this is like a $7 seal, I may buy seals for both sides. San Leandro’s parts page shows two different seals (driver and passenger are different). That seems odd, but is that true?
Should I use a Honda OEM part or does someone like Autozone, etc. sell a decent replacement part for this that I can trust?

I presonally would use all HOP parts. Also, probably wouldn't hurt to use some urea grease to get that seal in there. I doubt you need anything like liquid gasket, in fact, that'd probably be a really bad idea.

Re: (Eran)
Ok I just called and Honda the dealership near my house does have both in stock and the seal is different between driver and passenger side. So Honda OEM part it is...
Any other comments from anyone on my replacement method?
