How to grease the short drive shaft between trans an xfer case?

[jjb]

I was going over my 931 today. Checking all of the fluids and greasing everything. The front spring shackles didn't want to take any grease. Either they are rusted bad or maybe the fittings are bad.

Then I tried greasing the short shaft between the trans and the transfer case. I can't see how I can get a grease gun in there? Is there some trick? Do I need to disassemble anything?

I searched for this but can't seem to find anything. I've been looking through the TM's but have yet to find anything.

Could you use a hose kit to get to the shaft? You can buy a grease fitting tool at a shop to blowout thee shackle fittings.

Use a needle nose grease gun attachment. Have been told to keep an eye on this short assembly as it gets overlooked.

Are you referring to the needle greaser that can pierce CV boots? If so where do you put the grease? In each bearing cap?

There is a grease fitting there. I don't see why they would make it so hard to get at.
Something like this maybe?

No.

You simply push it into the ball of the zerk, then pump. One like in the pic below.

Not this.

For general purpose, use a 3' hose on your grease gun. Then take the end that goes onto the zerk and carefully grind the end a little thinner, so its tapered. Then it fits in between the U-joint crosses better. Size is usually not a problem on the heavier trucks though. If you can put the T-case/Trans in neutral, then you can usually turn it from under to line things up.

On the Spring pins, often its just dried grease and dirt plugging the hole. If you put some quick hot heat on it with a torch, then put your grease gun back on it, & it will get things moving again. Sometimes it just easier to pull the zerk, and run a small drill bit into clear the hole. Some are a pain though, and take all of the above. The cause of this problem, is not too much grease, but too little. Lubing regular, minimizes this problem.

I just had to do this on mine. I ground the tip of the grease gun down some and then took a die grinder to the yoke to make room. Worked great. Use a full face mask to keep the metal slivers off your face.

Picked one up at the local auto parts today. Worked like a charm. Thanks
