Lube the splines...

Take two of the right size nuts and screw on the stud, tighten one against the other, then tighten the top nut screwing the stud into the housing until tight, then with two wrenches loosen top nut and remove both nuts.

Use regular size nuts, not the coupling nuts, waste of money on coupling nuts.
 
Yeah, I bought a gen 1 a few months back and did the splines. They were bone dry and covered in that dried molly dust. Heck knows when they were last done. Luckily the splines were fine.
 
did you replace the 4 big bolts? they onetime use to my knowledge…
 
Thanks, Journeyman and all who contributed - post proved really helpful.

Pulled the driveshaft over weekend, 11.6k mi, both ends dry as a bone. Used the 65% moly Loctite paste. 3 of 4 studs backed out. Had fresh new studs on hand and used orange permatex on the coarse ends, blue on fine ends. Held mouth just right, slid right back together. A 17mm socket evaporated into the ether, but all in all, seeing what others already experienced/overcame made this a simple job.
 
LOL! yeah I'm familiar with that. I was using a small rechargeable torch a while ago, doing something on the bike on the lift, put it down & it's gone, disappeared. Never found it to this day, just staggering how it can disappear like that.
