Where is this grease coming from?

Wondering if NEW OEM axle shafts will have the same issue down the road with the small clamp being too tight and causing the boot to fail? I've been looking at Rock Auto and Auto Zone for axles with lifetime warranties. One specific brand on Rock Auto's site with "limited lifetime" specially calls out that the warranty is void if there is any damage to the boot! Hard pass - lol
"

The original boots were defective. No way they should be tearing anywhere from 10k to 60k miles and en masse. The replacement axles have a slightly different design with one more rib one the boot in question so I wouldn't expect premature failure.

I wouldn't assume that too tight a clamp, will affect every single CV axle that Ford has made, and I'm weary of 3rd party brands so would go with the Motorcraft. You might research the other brands, used in other Ford applications where the vehicles are older so a larger data pool to draw conclusions from as far as quality.

Anyone know what the splined knuckle bolts are, how they retain alignment if removed? I would have assumed that any time the bolts holding the strut to the knuckle were removed, that an alignment is needed and that's one of the alignment adjustment points?

I pinged Richard at Ford Boss Me on YouTube, as he has done some videos on this job, to get his opinion if camber adjustment is needed.
