Eyes misaligned(left crossed) when focusing, or relaxed. 2 yrs ago hit frontal bonecorner of wall. there was bleeding, no concussion. possible link?

Yes can be linked: Head injuries are 1 of the most overlooked causes of ocular misalignments & motility abnormalities. You may have had a concussion without realizing it. Concussion does not require loss of consciousness for the brain to have suffered damage. You should see a doctor for the potential concussion (e.g. neurologist) & a neuro-ophthalmologist for the crossed eye condition. Repair may be possible.
