Ford Edge winding and scraping noise while driving, possible PTU unit replacement needed due to steering wobble at high speeds on Ford Edge

Some Ford Edge owners report experiencing winding and scraping noises while driving, along with steering wobble at high speeds, which may indicate a problem with the Power Transfer Unit (PTU). These symptoms can suggest that a PTU replacement might be necessary to address the steering instability. Additionally, issues with the PTU can manifest as strange noises and may contribute to the steering wheel wobble, particularly at higher speeds. Regular maintenance of the PTU is essential to prevent failures, including checking for leaks and ensuring proper lubrication. Some owners may find that PTU replacement and related work could be covered under a powertrain warranty, so it's advisable to verify warranty details with Ford or their insurance provider. Furthermore, steering wheel wobble can also stem from other causes, such as tire imbalance, low tire pressure, or worn-out tire treads, all of which can affect steering stability. If these symptoms arise, it is recommended to have the vehicle inspected by a qualified mechanic to accurately diagnose the issues and determine if PTU replacement is required.
