CV axle seals help. (2 Viewers)

[LandForce1]

I haven't posted in a while, forgive me. But I have been researching alot. Im installing new OEM front cv axles on our 2006 LX-470, it now has about 170k miles on it. I have owned it since 2016. When we bought it, it had about 107k miles on it. I replaced wheel bearings a few years ago. But now im replacing the cv axles and all seals related to them. I have a few questions.....I installed this seal into the passenger side differential. It seated about 1/8" deeper than the old seal was that I pulled out. Is the new oem seal seated too deep? I will have a few more questions coming in over the weekend. Any advice is appreciated.

The first image is of the old seal and its depth before I pulled it. The second image is of the new oem seal that I very carefully drove in, until it fully seated.

I forget which side but one seal goes in easier than the other since you can push it in past flush. Double check the part numbers as well.

Thanks for the response! I double, triple checked the part numbers. I believe this is the proper seal for the passenger side differential. Exact same as the seal I removed. This new seal just seated in a tiny bit deeper than the old seal. I will post a Pic of the part number on the bag tomorrow. Maybe its wrong, but it seemed to be identical. Maybe I seated it too deep? Or maybe the old seal wasn't seated deep enough?

Is there a shoulder that prevents the seal from going in further? Like I said, one side is easy to mess up since you can push it in too far. It’s been a while but they should sit flush.

No, there is no lip that prevents driving in too deep. Measure the original and drive in the new to match. I used a 3/4” wooden dowel from Home Depot. @2001LC has a YouTube video of him using the same dowel shaped a little on the bottom. If you have time I believe @cruiserpatch sells the factory service tool for driving these seals in. The SST allows the installer to drive both seals in care free. The tool prevents under and over driving of the seals.

New seal is over-driven. These do not get driven in until they stop.

Great, thanks. I guess I need to sneak it back out a bit or install a new new one!

Next quick question, the old paper gasket under the large dust seal did not appear to have any gasket sealer on it. When I install the new paper gasket, should I use gasket sealant (permatex ultra black) or should I leave the paper gasket dry?

I’m pretty sure the driver’s side has a lip.

Proposed addition to FAQ- Front differential seals.

As a newbie, I found any mention of the seals in conjunction with the CVs leading to details on the seals as lower priority. The one takeaway was to not push the seal too far in. I did not realize this was exclusive to only the passenger side as the driver's side has a lip and different seal...

I just brushed both sides with a little red grease.

I grease mine as well.

Great, I will do that instead of the permatex. Thank you!
