Front end condition question and future maintenance

Hello,

i have just purchased used 012 TRD V6, i had mechanic to help me inspecting the vehicle and followed his advice on proceeding with purchase.

Car has 110k KM on it and came from original owner, maintenance and fluid changes were done on schedule by toyota dealership except differential fluids and transfer case fluid which ill be changing this week along with second set of spark plugs.

What iam looking for is feedback on amount of rust around front end differential - looking at the photos, particularly frame above and on CV axles

CV axles joint has cracking layer on it too (see the beggining of the video) - something i noticed just today

is this amount of rust really concerning or normal ish ? (rustbelt area PNW, howewer car is only 110k) and can i do going forward ? what can i expect ? can this be cleaned and coated to really make a difference and will any of these components likely need attention in near future for premature wear ?

how bad it really is ?

outside of that any other tips would be appreciated

any perticular bolts / joints i should keep my eye on or release regulary to keep from seizing etc ? (like brake calipars)


thanks for any input
