I just did this exact same thing to my 1356, they slip yoke would start sliding in nice and snug, then got very loose, it showed more when the extension housing was off, I had to replace the extension housing as it was cracked at the bottom, and got a used one from the wreckers, it was the exact same issues, and as leeland's yoke was, mine you could see ripples and necking on the yoke its self. I got a new slip yoke from a local driveline place for 70 ish bucks and ordered the 1356 rebuild kit from bronco graveyard and the kit came with the new bushing. The guy at the local driveline shop warned me that the aftermarket bushings were usually too tight and the yoke wouldn't fit, the one I got was a perfect fit. As for replacing the bushing, the old one almost fell out with a bit more then hand pressure, but I used an aluminum bearing driver to put the new one in and it was tight. To check the bushing, see how wide the oil groove is, you may not need to change it, though if most of its gone(small groove) then it defiantly needs to be changed.

I do also recommend while your at it, to do the oil pump mod so it doesn't chew threw the case and take out your t-case and the washer behind the shift leaver to get rid of the possibility of the shift forks falling off(mine were only contacting it 1/4 of the full engagement.(Do a search, these are very common issues and very easy to fix to make it bullet proof)

Have no plans to split the case. If I have to eventually, the pump mod is deffinitly going to be done if I keep it but probably getting ditched for a 205. Already have another yoke donated to me by Kenny aka bookite03. Just trying to take care of the vibration for the time being.

Good to know.

No bueno. Found this galling when pulling the axles out of my rclb. Be putting in the new bushing soon, kinda curious as to what the old bushing looks like now.

Blumenthals in Oklahoma. I use them for GM Trans and Cases. They talk like they carry parts for all brands.

Most BW cases are considered obsolite now days.

I have the bushing, a slip yoke is going to take the better part of a hundo from the same source. And I'm sure the stealership could have got it, parts guy was just being a idiot. Might be surprised what parts they can dig up when your dealership is the one asking for the parts.

I don't know, never had or heard one chirp.

I had every I intention of having the housing off by now to inspect and replace the bushing considering how my slip yoke looked but I've had some really fawked circumstances come up.

That was my whole frustration and why I asked the forum. Couple suggestions made where to find one already. Wasn't too long ago when I replaced the output seal in the gasser 250 I had and at the time autozone sold the seal with the bushing as a kit. Think that was mid 2011 when I moved home and was lifting it. I recommend if you have a local driveline shop or dealership that you stand in front of them not call.
Is yours slinging ATF?

It's been throwing a little. Just enough to keep it wet, but not coat the underbody.

The seal has been torn for awhile, just now started having a vibration, noise now and then, and it'll shake good when engine braking.

How much slop do you have with the load relieved from the drive line and have you inspected the slip yoke for wear?
Or the u-joints etc to see if your vibration is else where?
