How to Fix the Alignment on Car
Try the few steps as explained in the link i have sent you. Hope you get best results.

Without proper equipment it's not likely that you can get it right. I suggest that you take it in for an akighment.

take it to a shop that does alignments and get it inspected, sometimes an experanced eye will see something you might not. then have a 4 wheel alignment done. this is the only right way to do this.

replace anything that was bent and then have the rear end alignment done at a wheel alignment specialist shop
any specialist shop when doing a front alignment should always check the rear first as it controls the accuracy of the front job

An Alignment shop can adjust it,

There is a rear suspension offset toe link
bolt avail for around $ 12.00 ea

Google--- 2005 buick lacrosse rear toe out adjustment

Did you not answer your own question?

Your the one under there--looking & pushing
& pulling on the suspension

Now the question is---do you have the tools &
experience to replace parts?

There should be an adjustment with a lock nut and the ability to spin the tie rod to adjust the toe inward to compensate for the outward toe that you have. Best to have a 4 wheel alignment machine to check out the exact measurements, say at Sears Auto for instance.

put your feet pigeon toed, that's TOE IN, now put your toes outwards, that's TOE OUT. Toe is critical for tire wear. when toe is out or in, the tire "scrubs" along the road and wears faster.

There is likely an eccentric bolt on the lower contorl arm. The one on the arm closest to the bottom center of the wheel hub is the camber adjustment, the other eccentric is the toe adjustment. You really should have it aligned with a computerized alignment machine. Changing the rear camber changes the rear toe and vise versa. It would be nearly impossible to get both within an acceptable range without the proper equipment. You can crudely measure rear toe using a tape measure but you won't know what the thrust angle is and that could cause some serious alignment issues.

Get an alignment. Any time you change any part of the suspension or steering or even the engine cradle in your case, you'll need to take it to a shop for an alignment.
