I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. someone thought it had something to do with the wheel bearing, but that does not seem to be the case. ??? ---

Does the knocking increase with engine rpms or with wheel rotation speed? If it’s tire speed, front u-joint. ---

The knocking does not increase with rpms or speed. It goes away pretty fast. And it’s not purely “knocking,” it’s like a knock and a ping at the same time.
