Post CV Axle replacement questions

Just changed out both cv axles on my 2018 TRD Off Road 4X4.

A few questions:

I’ve got a small positive camber on my front 2 wheels, assuming I just need an alignment after the new cv axles?

There is a loud pop coming from the truck now when driving. Everything was torqued to spec. The new CV axles were slightly smaller than the old ones, but they sit the same at driving level as the old ones did.

Where could this popping sound be coming from?

 

Should have bought Toyota axles.
Good luck with your truck.
