Re: bushing puller

Just reread my post. Forgot about the bushing. Is the trans in or out of the car?
What is causing you to believe the yoke bushing is bad?

The bushing should be easy(er) to remove with the tail shaft off the trans.
You can get creative with a seal/bushing drivers and about anything you can find that fits the bushing to drive it in.
Driving it out will be little bit more involved if you cannot get behind it?

The slide hammer kit may have the right adapter to get behind it? You may be able to work it out with a drift. Few different ways to skin that cat.

I admit Ive not played with an early Muncie. But I have played with many others autos & sticks. Autos have plenty of bushings. The two kits below and a seal driver kit are all I have ever used.

For the seal the slide hammer with a hook attachment or the rocker lever style puller will make short work of it.
Both are inexpensive. You may need both of these tools.

Be careful to not gouge the ID of the tail case during bushing & seal installation.

A small sharp chisel & tap hammer can be used gently to break the seals seal around the outer metal lip area to coax it out.

If the new seal has the tension spring (spring loaded seal) on the transmission side of the rubber lip, pack it with Vaseline to keep in place while installing the seal & guiding the yoke back into the trans.

Clean the trans case ID of oil/grease. Run a VERY thin coating of "The Right Stuff" gray RTV in the tail case ID surface and on the seal OD before tapping in the seal.

I have had good luck with all types of seals with both of these tools in my box.

Make sure the yoke doesn't have a groove in it. If it does replace it.
A Speedy Sleeve is an option but it needs to be the right size and installed correctly. The surface needs to be prepped in a certain way as well.

Bearing Distributors Inc (BDI Inc). will have the seals and Speedy sleeves...USA made if you ask.

Re: bushing puller

Steve,
I have the Snap-on Rear Axel Puller Set that would likely work for your application. Not looking to sell it, but you could certainly borrow it for your repair. Might be cost-prohibitive to ship/return it if you can just have a shop pull the bushing locally. Where are you located? I am in North Carolina.

Regards, John

Re: bushing puller

hi David
no worries..honestly i don't know if the yoke bushing is bad. i haven't gotten under the car yet to check for any play. just getting my
ducks in a row. just figured if i'm down there replacing the seal i might as well replace the bushing. i have located a miller tool to remove the bushing. tail housing and tranny are still in the car. i think it would be a very educational experience, however sometimes i believe some things are better left to the pros. thank you for all your info and help.. steve

I don't know how this bushing could be removed with the transmission assembled and installed in the car. I don't understand how ANY tool could do it properly. I'd be loathe to even try it. The seal can, of course, be rather easily replaced with the transmission assembled and installed in the car.

GM only specified a procedure for removal and replacement of this bushing with the extension housing removed from the transmission and I do not recommend trying to remove the extension housing from the transmission with the transmission installed in the car.

With the extension housing removed, the bushing is driven out of the extension housing using Kent-Moore tool J-5778. The same tool is used to install the new bushing. I believe there might be substitute tools available to accomplish the same task.

The snap on tool that he asked about in the first post was designed to replace the bushing in the car without removing the tail shaft
i am trying to find a picture of it

Re: bushing puller

It is a very thin gauge metal that will slip over the main shaft, has "fingers" that will grab the back of the bushing and a jack screw to remove it. Here is one, I don't know if it is for Muncie, they made several. This is not mine, just found the picture online.

If one KNEW the bushing was bad, it might be worth trying the tool as one would have nothing to lose. If it did not work out, one would have to remove the transmission anyway. But, I think it's unwise to try to remove it pretty much on a hunch that you might need it and having absolutely no experience using the aforementioned tool. This bushing is relatively thin. Trying to remove it with a tool that operates as Gary describes wouldn't be something I'd do (unless I had nothing to lose).

For the most part, the bushing is replaced as part of a general transmission overhaul, not as part of "routine maintenance". If it needs to be replaced, there's a good chance that other parts need replacement, too.

Re: bushing puller

great points bob and joe... i think i'll be happy just replacing the seal and roll the dice. whatever extra time i get by just doing that will be a gift.
i will check the play and the condition of the slip yolk for sure. i'm reminded of the old saying " if it aint broke don't fix it. with this plan of attack
in mind , i'll perhaps save myself alot of grief..!!!!
thanks men for all your insights ,
best regards,
steve
