Ford tells me i need a driveshaft and a rdu. Really shaking bad,especially high speeds. Bad shake. No lights are on. Does this sound like the problem?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Yes, axle shafts are often the cause of vibration. You can see the shaft even doing it with the vehicle in the air sometimes. If you've eliminated a tire concern and a wheel concern -- then the next step is indeed checking axle shafts. An out of balance axle shaft will not set any warning lights. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
