2018 Chevrolet Tahoe — steering wheel vibration only at one highway speed
2018 Chevrolet Tahoe LT, about 119,000 miles. The car is smooth around town, but there is a noticeable steering-wheel vibration in a narrow highway speed range. It gets better again above that speed. Tires look normal at a glance. What would you test first before replacing anything? Interested in real owner experience more than guesses.
