1/4 per 10 degrees.
1/4 what?
The pinion angle looks to be as good or better than the majority of the rigs on planet earth. Are you sure it is any different than stock?
I think the people that have bearing problems have the pinion pointed directly at the t-case. If you are worried put some synthetic in it for added protection.
Honestly, I don't understand the concern, but maybe someone else knows more?
