Are you planning a road trip soon?  If so, be sure to have your alignment checked before you leave.  When a vehicle is out of alignment it may pull to one side, or cause dangerously uneven tire wear, a problem that can go unnoticed until it’s too late and you have a blowout.  Other components including ball joints, struts and shocks can also be affected.  Even if you don’t have a road trip planned, schedule an alignment adjustment if you've noticed any warning signs, or if your vehicle is overdue for this service.
