My standard grease gun nozzle has a hard time fitting over the zerks on ujoints because the knuckles(?) are blocking the way. Should I file down the sides of the nozzle? Is there a smaller version?

I've looked on some other forums and people seem to suggest dropping the shaft to grease it, which is not that hard but still a PITA for something so simple.

 

You've still got to drop it to grease the centering ball either way.

 

I bought a second grease gun fitting and took it to the belt grinder and thinned down by creating two flat parallel sides. Works great for me.

 

yes, but as stated earlier you have to drop it to grease the centering ball

 

Question: I still have the original front prop shaft (going to get a replacement soon). On the original, does it have a centering ball grease fitting requiring it be dropped? Or is this just on the replacement shaft? Thanks.

 

just replacements, the oem does not have a way to be greased, hence the problem
