- 03 XLS, 06 Mounty
Purchased an 06 mounty 4.0L recently with 128k on it. When I bought it, the guy told me he had replaced the drivers rear cv shaft. It was nice and shiny. 5k miles and 3 months later, the diff seal on that shaft failed. When I went to replace it, I noticed someone had tried to remove it and failed. So it was obvious why it had leaked. I replaced the seal with a ford seal and everything has been great until now. 5k more miles and 3 months later. The seal blew out again. This time, the cv shaft was pushed out as well.
Is it possible that the “new” shaft is faulty? Too short? Not the right diameter?
Also, how much play should there be in the diff side of the cv? Mine wiggles a little, but nothing crazy.
I’m a seasoned heavy equipment fleet mechanic but this is not my forte. It’s got me stumped. I’m going to replace the seal again. This time I purchased a new shaft to compare to the one that’s in there.
I thought maybe the axle bearings were bad but they’re quiet as can be and the cv shaft doesn’t show any signs of wear.
All thoughts are appreciated. Thank you!
