I agree from your pictures there is some cause for concern. That large gap at the base of the tree indicates something that needs a professional assessment of the whole tree.
Such an important decision cannot be made by looking at pictures online.
What I recommend is that you hire a certified arborist. This is a professional who is trained in pests, diseases, and the healthcare of trees and shrubs, and passed certification testing.
To find certified arborists in your area here is a website where you may search my ZIP Code. Look for arborists who have the “tree risk assessment qualification” (TRAQ).
