Anyone know the size of the threads of the fittings on the cv end of a stock front driveshaft?
 
There is no real "zerk" in the CV joint,at least on the older trucks I'm used too--most have a inverted cone shaped fitting and a needle point tip on a grease gun goes onto it,you have to hold pressure against the tip to get any grease to go in,and its a bear to get at..the inverted cone fitting might be threaded,if it is it might me 1/4x28 thread like a typical zerk fitting,as is used on the sliding slip yoke end,and most front end components like ball joints ,tie rod ends,etc..
 
Yea , I what to put one on that uses the needle. The driveline shop that built it put a 90 degree on it facing inwards so you cant get a gun on it.Even better to unscrew it would require disassembly of the cv. I'm going to cut the fitting of with a dremel , then unscrew the base. Just wanted to know the size of the threads so i could have the replacement on hand. I don't have time to take it back to the shop , all i would do is yell at them for them wasting my time.
 
Maybe you could just chop off the zerk part and leave the base in,and drill into it to make a inverted cone shape..then be able to grease it with the needle tip...you wont have the little check ball any more,but if you greased it regularly I doubt any water would get in the tiny hole..

I could never grease that fitting on my front shaft while it was installed ,except when I had the center tunnel out and was able to turn the shaft till the fitting faced straight up,then I could get the grease needle tip in the fitting--still was a beotch to do though...they could have designed it better..
