hermanmullins Report post Posted February 11, 2013 JB, Welcome to the Forum. Is your GMC 4 wheel drive? If so yes. Your suburban will have a steering wheel lock and you would need to leave the key in the first position. It is also heavy enought to require a auxilary braking system, a braking system should be on all toads. Herman Share this post Link to post Share on other sites
