1992 Chevrolet G Series Van (G20) Q&A
1992 Chevrolet G Series Van (G20) Question: it vibrates badly until 35mph then at 57mpn, loud inside but not heard outside.
Do you feel the vibration in the steering wheel if so the front tires are the likely cause, if you feel the vibration more in the rear it is likely to be the rear tires "out of balance". Visually look at the tires do they look OK look evenly worn? Go to a tire store ask their opinion and perhaps get the tires rotated and balanced as required. - patrick mannion
