    Default Rear Main Seal Confusion

    Ok, I am trying to buy the right part the first time. I have an '05 TJ and every write up I see and pictures in the parts fiche show the lower half of the rear main seal with the little ears on it. Every parts store I have been to is showing me one for my year model without the ears. There was a parts number change in '00. Which one do I get? With the ears or without? Anyone that has changed one in an '05 chime in please. The FSMs for '05 and '00 do not specify the difference.

    Here is the difference I am talking about.







    Here is the parts fiche image for '05 TJ





    Here is the parts fiche image for '00 TJ

    They probably used the same diagram for the 'fiche' for both, only changing the part#'s.

    I would use the seal for the '01-'06.

    Better yet, buy both seals-after you replace it with the correct one, return the other.

    Then post up in the 'tech' section with pics, for the next guy!

    Plan A - Post here and find out which one to buy.

    Plan B - Buy both and take the one back that I didn't need.

    These were my plans, but I figured someone here would know.

    Go to the dealer. The seals aren't that expensive, and the dealer should give you the right one. Make sure to get a new oil pan gasket while you're at it.

    Already have oil pan gasket and everything else. I just need the rear main seal. I asked dealership about it and they said they just carry the one with ears and just cut them off of the ones that don't need them. I am sure they are more than happy to have people return over and over and over again. I don't trust em. They didn't even know that the Mopar anabolic gasket maker exists that the FSM calls for instead of RTV on the lower half of the seal.

    ummm.....yea....that doesn't sound like a dealer I would listen to. Have you walked back to the maintenance bay and talked with a mechanic?

    When I have tech questions, that's what I do...just a thought! Let me know what you discover please...I own an 05 LJ and suspect at some point I may run into a rear main seal replacement!

    HOOYAH!!!
    Best of luck!

    HOOYAH!!!

    Got it apart tonight and putting it all back together with new seal in the morning.

    '05 takes rear main seal WITHOUT the ears on it.

    I've ran into that with my CJ and tractors, where they use the same blow up of the engine/tranny/etc. for different years, and only change the part# on the list.

    Can be confusing sometimes, like in this case, where it shows one thing, and calls for another.

    Glad you figured it out! And now we know!!

    Got it all buttoned back up. I tell you unhanging and hanging the entire exhaust system by yourself is a tough task. It helped to disconnect the bottom of the pass rear shock to get it out of the way and jack that side up by the bumper so the axle would droop. That gave the bends in the exhaust room to be maneuver to get it back in the hangers. Other than that it was all pretty straight forward except the top portion of the rear main seal was pretty tough to get out. I also made some guides for putting the oil pan back on. I used some 2" long 1/4" bolts with the head cut off on each corner of the oil pan holes. Made it a breeze to slip the oil pan back on and get everything lined up.
