I am sorry but there is no fix to this problem. Those trees have a severe case of sunscald which happened when they were younger and has only gotten worse. What you are seeing is a callus in the tree's attempt to survive. The third photo also shows that the lower part of the trunk is narrower than the upper portion. That is an indication of stem girdling roots. That tree was probably planted too deep or soil was piled up around the base. Both trees are probably dying. You probably should have a certified arborist make a house call and diagnosis. I am giving you three links. One to explain sunscald, one on winter injury and one a link on finding an arborist. On the one click on Find An Arborist. Once your location information is filled in a list of certified arborists in your area will appear. https://forestry.usu.edu/news/utah-forest-facts/sunscald-injury-or-southwest-winter-injury-on-deciduous-trees#:~:text=Partial%20List%20of%20Trees%20Susceptible%20to%20Sunscald%20,Crabapple%20%20%20Maple%20%20%20Willow%20     https://www.mortonarb.org/trees-plants/tree-and-plant-advice/horticulture-care/winter-injury-trees-and-shrubs      https://www.treesaregood.org/
