Getting a W463 to track straight is a recurring frustration, and even dealer alignments to factory spec can leave a car wandering; the advice is to use an independent shop that understands solid-axle setup rather than the dealer. Worn drag links and tie rods are common: a drag link part runs about $290, a full Hamburg links-and-rods kit about $500, and a comprehensive steering job was quoted around $2,000.
