Might be time to invest in some manual hubs & the TOD off switch. Even if you don't use it often, its nice to have when you run into problems.
I had binding issues with aftermarket CVs. The best way to check if you're having the same problem is to jack up the front end which will allow your IFS to go to full downtravel & then spin the each tire. Next try the same thing with the tires at full turned position. The tires should freely spin and have no resistance. When my CVs were binding, the tire only turned halfway smoothly & then I had to pull it around through the other half of the rotation.
