I haven't installed yoke yet because I got the wrong size jam nut. The nut I got was for a 12 bolt and has a bigger outside diameter. Same thread size but you can't get a socket into the yoke well. I have a 10 bolt and must have called everybody on the East coast looking for a new nut. I finally found on the net a company that had them and was a pleasure to deal with. They probably lost money processing the order for a $5.00 part. They are , National Driveline, 877-910-2244. I'm going to put a thin coating of sealant on the splines, great idea and thank you.
