Hope you guys/girls can help me..installed cedar fence with 6x6 corner posts
in concrete roughly 30" deep in Dallas, TX. Height is roughly 7'.

It has developed a lean to one side, pulling away from the fence line,and is
quite noticeable, perhaps15 degrees or so. The side it is leaning too has
about 6" of ground betwenn the concrete and the curb.

This post has no stress on it other than about a 6' length of bamboo
fencing, opposite the lean, which weights hardly anything. Rest of fence is
fine.

How do I get this post upright without breaking it all apart and starting
over? Really would hate that.
