If the vehicle has been wrecked and the struts are damaged, they should be replaced. If the problem is just the alignment, new struts may not solve the problem. The thing to do is install alignment bolt kits. These kits are designed to allow movement of the strut at the spindle to allow resetting of the camber to get it back within specification. There are several companies that sell these kits. One is included in the link below. Do a google search for "honda crv alignment bolt kit" and you will find there are tons out there.
