    Leaking axle seal?

    I have had this fixed before but after a long road trip with a few jaunts into the 80-90mph range and I discovered oil splatter inside the wheel. I don't see anything from day to day driving just after road trips. Anyone have a fix? Thanks.

    If your MM was built before 1/1/03, it could need the axles, bearings and seals replaced.
    (#6178 in black per FPIC)
    Call 1-800-FORD-788 and press "1". Have the last 6 of your VIN handy. You will get the numbers for FREE. You'll pay $$$ for the certificate.

    MM traded in 8/9/13 @ 128909 miles. It was fun for almost 8 years. I met airmercpun on 1/17/14. He was the new owner of my former ride. -Now gone.

    Update: back in the game with a late build 03 GMGS with some MM add ons like Escape audiophile radio w/Sirius sat radio, rear sway bar, catback exhaust, and header panel.

    Rest In Peace:

    See my garage file for part numbers and whatnot.

    IMHO, this site- the members that I chat with- and the ones that I now Hang with- are like my 2nd family. There is such an ongoing welcome feeling here that even members who don't or no longer own the MM can feel.

    When you say fixed what was done? I would check that the axle fluid is not overfilled and the vent isn't plugged if those are OK. Remove the axle check the machined face for scoring, if damaged replace the axle, axle bearing, & seal. If the axle is OK just replace the seal and bearing.

    This does not appear to be the axle bearing problem. In the axle bearing problem, noise develops and metal particles would show up during a differential gear oil change. This was a pre-Jan 2003 Build Date problem.

    You may have a balance or eccentric shaft problem where the seal can not fully seal during high speed.

    Also when a new axle seal is installed, extra care must be taken to prevent the axle from nicking the seal. If the seal is nicked, it will start leaking early. The cheapest solution is to replace the axle seal again.

    For the other problems, I would consider looking for a junked 2004 Marauder. Buy the rear axle assembly and swap out.
