    I needed to replace both front CV Axle shafts on my wifes ALL-WHEEL drive 98 Explorer. I bought NEW shafts as they were only $10 more each than reman. The driver side took 3 hrs (first one I did), and the psngr took 2 hrs. All went well, and drove on the exprtessway for 30mins and everything is fine. This morning I went out to the garage and the passenger side has a couple drops of gear oil on the floor. I looked underneath and saw that both sides had a bit of oil splatter on teh suspension, but the driver side was not dripping, the passenger side has a few drops. How long should I wait to see if it stops before I pull the axle out. What should I look for? Everything seemed fine, and nothing was torn when I checked out the seals before I inserted the axles.

    If its gear oil, you have bad- damaged seals on the front differential output. you can weight as long as you want, I've never seen a seal get "better"

    Not hard to bugger up the seals when doing a shaft. You didn't find a little circular spring laying on the ground did you? It doesn't take much to catch an edge. Unfortunately replacing the seal is re-doing the work you already did.

    Well, bought the new seal, a seal puller, and tore it apart today. I saw right away the problem...the old seal had a piece that was sliced and just hanging by a thread.

    I told my wife I can only charge her for the FIRST time I tore into it...the second time was a freebie...all she wants is "her baby" back and driveable.

    Anyone in Chicagoland need their Explorer CV axles changed...I can do it with my eyes closed now.
