Is there only 1 grease fitting on the drive coupler? I can't see the dang thing, but can only find one fitting. The service manual just says to grease it, not how many fitting there are. Thanks, Ed

Parts diagram shows 3, one on the spline coupling and one on each u-joint.

If someone replace the u-joints with different ones the grease fittings may be on the cross instead of the end caps.

Thanks, I found them, 180 degrees opposite the coupler fitting.

Is there any slop if so change them for a hundred bucks will cost alot more if they break
Nope, no play in them. By looking at them with a mirror, and just putting my hand back there, it appears the previous owner actually greased them. Working in the auto industry, it was a nice surprise to find something that has actually been maintained, as that seems to be a rarity these days.
