NP 231 Yoke Seal

Have to change the seal on the tail shaft. Lo and behold the tail shaft is damaged from previous work (that's where the leak was). Have the new tail shaft cone, seal and yoke. Thinking it would be easier to install seal on tail shaft before I bolt it back in. Working on my back and all. Good idea or not so much.

I would definitely install the seal on the cone prior to bolting the cone on the housing.

Is there a bushing in the new cone already?

I think Max meant to say "bushing" in the tail cone (housing extension) behind the seal. You'll want to make sure that is in place or you will leak ATF even with a new seal. I think I used a 30mm socket to replace mine.

Glenn--already installed from Quadatrac. Nice Renegade, should post mine. Mostly stock except for tires and some diamond plate bolt on stuff. Getting it back on road for warmer weather, gets better mpg than my Tacoma.

Thanks. Post a couple...not many of us guys left! Putting a family bar in this weekend. New pads showed up today. Feel better with 3 point belts in the rear.

Keep in mind that if the slip yoke shaft is worn, you will still leak even though the bushing and seal are new. I learned this first hand.

Me too! I replaced the seal and bushing and it was still leaking. Once I replaced the yoke...problem solved.

Oh goody---I'll try this first with the new housing, brass bushing, seal, yoke and u joint. If not, that's why they make oil drip pans for awhile.

Wow...that bad boy still as the original front skid plate on it. I'll assume the rear is on as well.

I'm talking to a steel fabricator (who I do work for) to re do them in aluminum diamond plate.
