Chevrolet Impala severe shaking and whining noise from rear with undiagnosed issue on Chevrolet Impala

Some Chevrolet Impala owners report experiencing severe shaking and a whining noise from the rear of the vehicle, which may be attributed to several underlying issues. The shaking could be caused by unbalanced wheels or tires, low tire pressure, or worn and unevenly worn tires. Additionally, some owners have noted that a whining noise may stem from problems with the power steering system, such as low fluid levels or a defective power steering line. Other potential sources of the whining include the starter not fully engaging with the flywheel, issues with the alternator or power steering pump, or low transmission fluid levels. Furthermore, some owners have reported that problems with the rear end, such as tire whine or drive shaft issues, as well as clunking noises from the rear suspension, may contribute to these symptoms. It is recommended that owners seek a thorough inspection by a qualified mechanic to accurately diagnose and resolve these concerns.
