Need clarification before ordering parts for axles, seals, ball joints...

[2001x4.4]

So my friend has talked me into tackling this job rather than sending it to the stealership or indy. I have to replace both of my front axles. It appears that most people on here use Empi with good results.

I am set to order the following parts:
Output shaft seals:01 2001 BMW X5 Output Shaft Seal - Transmission - Corteco, National, PartsMaster - PartsGeek

Empi axles:
01 2001 BMW X5 Axle Assembly - Driveshaft & Axle - EMPI, First Equipment Quality, A1 Cardone, Front Left, Front Right, Rear - PartsGeek

While I am in there, I will also replace the ball joints pointing downward. Are these called the front lower ball joints? #15 from the diagram.

Much appreciated if someone can provide inputs into whether these are the correct parts.

Thanks in advance.
