  • The rear output shaft on the Dana 20 transfer case is known to wear down and leak at the rear yoke after years of use. To fix this, there are a couple things you need.
    1. New Dana 20 yoke seal: tomsoffroad.co...
    2. New Dana 20 yoke: tomsoffroad.co...
    3. Dana 20 Speedi-Sleeve: amzn.to/39Ffbt0
    To fix the leak at the rear yoke:
    1:43 - Remove the rear drive shaft
    1:47 - Remove the 1 1/8th nut holding on the rear yoke.
    1:55 - Use a harmonic balancer puller to remove Yoke
    2:09 - Remove Seal (I’m not removing the seal housing, just the seal)
    4:10 - Inspect the rear yoke, replace if necessary
    4:46 - Or Install Speed-Sleeve if needed
    6:01 - Install new Seal
    6:43 - Install yoke
    7:05 - Tighten down nut to 150 ft pds
    - Re attach rear drive shaft
    Now I’ll make a disclaimer right here, this would be a great time to upgrade to the HD Rear output shaft from TBP. It’s about $500 and beefs up this output shaft because the have a tendency to break on the trail. I’m not doing that today, we are just fixing leaks, but it is on my list of things to buy and it should be on yours.

    Screw a couple of screws onto the seal and either pry or use a slide hammer

    Good one John. I did the whole rebuild last year, this brought back memories.. although I was like a kid handing his dad tools with my friend doing all the work 😆

    Could you have used grease to lubricate the yoke and seal before reinstalling them or is it not recommended?

    I'm sure mine leaks to some degree too. Still the original transfer case, lol.

    What gear oil do you use for the Dana 20?

    • @okbob4959
      @okbob4959 2 місяці тому

      The manual calls for 50W engine oil.

    I would advise locktite on that nut! Had mine come off going 60 mph down the road with a half cab on! Needless to say I 💩 my pants! 😉🤣😎

    I didn't see a O-ring or sealant under the yoke washer?

      Myself I just use rtv silicone sealant in place of the o ring that works just fine
