Does a 1993 Mercedes require four wheel alignment?

Yes, a 1993 Mercedes-Benz, like most cars, requires a four-wheel alignment. While some older vehicles might have been designed with adjustments only on the front wheels, Mercedes-Benz, even in 1993, generally had adjustable components on both the front and rear axles allowing for a full four-wheel alignment. Getting a proper four-wheel alignment ensures optimal tire wear, handling, and steering.
