Haha I prefer to stay at 45 as well, but that makes Moab a lonnnng ways out

Anyway new cv is in. Nearly all noises are gone except for the coasting/decel sound. It seems to be way way less than it was. Although it could have been multiple sounds since the old driveshaft had a bad ujoint and play in the splines.

I'm waiting on some 10 deg shims to get my angles totally perfect. I have 8 deg in there now but I have some highway vibes due to that being off.

Quite possible the sound is just gear noise and nothing more. I am lacking carpet.

Couple side notes - I did need to notch the horse collar to get the cv to not rub. It looked fine but under heavy torque it made contact. Also, the driveshaft I bought "seemed" to have no play when I picked it up from the yard, but after my driveshaft guy cleaned it there was massive play in the splines and a bad ujoint. Go figure.
