Your problem is most likely that your tires need to be balanced. Occasionally you lose a weight and you get a shimmy at a specific speed usually between 60-70 mph.

Similar problem with our '99 Suburban was due to bad universal joints. The OE joints cannot be lubricated and will lose their lubricant by 90,000 to 120,000 miles. Replacement u-joints have lubrication fittings on them and should last much longer (if you grease them).
