Ok. Lots of threads say you need to drop the shaft at output to grease the center ball. A few threads say you can do it without dropping it.

I'm about to attempt to grease it (my first attempt failed when the needle broke) and I'd like to do it without dropping the output. So what is the trick?

 

Well, when I had mine rebuilt they put on extenders on the U-joints that stick out further so I can get the tip in there, not sure what others have done.

If you are actually talking about the centering ball, I thought that was supposed to be a non greasable part.

 

i don't know of this extender, of which you speak. does it protrude out of the housing, for the centering ball? or do you mean for the u-joints, only?

 

They're just longer zerk fittings, that's all.

 

gotcha, thanks. I thought i was missing out on some fancy new fangled long needle fitting.

 

well if one of the manufacturers would offer this or it was a do it yourself job then i'd be all over it.

 

yeah, no kidding. I have an extra front shaft. I take it under, as i drain the oil, swap it out, and get that one greased for next time. talk about high maintenance, i feel like i have a second wife.

 

Ugh! I didn't realize that the Tom Wood's shafts and others used a greasable centering ball. I got a sealed centering ball when mine was rebuilt, so disregard everything I mentioned.

 

I'm starting to wonder what would be worse: Dropping the shaft and greasing it 2x+ times a year, or putting in a non-serviceable centering ball and rebuilding the centering ball every 75~80k miles.

 

After rebuilding my driveshaft tonight... man, if you can get a greasable centering ball, do it.

Replacing that centering ball was a total pain in the ***.
