REPLACING REAR STRUTS

2002 Buick Lesabre

Suspension problem
2002 Buick Lesabre 6 cyl Front Wheel Drive Automatic 110000 miles

Can I replace the rear struts without a alignment being done? They look like regular shocks other than they have a small air line attached. It does not appear to me that you are changing any adjustment that would require a re alignment.
