I have a large, old walnut tree in my front yard. The bark on the east/northeast side of the tree is separating from the trunk. Is this a sign of disease or other problems? And can I peel the bark off the tree or will that hurt the tree?

There has been some reports of Walnut Twig Beetle and canker diseases on walnut, however the bark peeling usually is on the south west side of the tree. Don't know without photos or other information what the cause of the peeling bark. Do not peel off the tree, more injury may occur and generally not recommended.
