The parking pawl is a small metal bar that engages with the teeth of the parking gear when the transmission is shifted into park. This prevents the vehicle from rolling away when it is parked. When you turn the wheel while in reverse, the parking pawl disengages from the parking gear and allows the vehicle to move. The clicking noise you hear is the sound of the parking pawl engaging with the parking gear again.
If the clicking noise is accompanied by other symptoms, such as a grinding noise, a burning smell, or difficulty shifting gears, it is possible that there is a problem with your vehicle's transmission. In this case, you should have your vehicle inspected by a qualified mechanic.
Here are some additional possible causes of a clicking noise when backing up and turning the wheel in a Chrysler Pacifica:
- A worn or damaged constant velocity (CV) joint. CV joints are responsible for transmitting power from the transmission to the wheels. If a CV joint is worn or damaged, it can make a clicking noise when the vehicle is turned or accelerated.
- A loose or damaged drive axle. The drive axles connect the transmission to the wheels. If a drive axle is loose or damaged, it can make a clicking noise when the vehicle is turned or accelerated.
- A damaged wheel bearing. Wheel bearings allow the wheels to turn smoothly. If a wheel bearing is damaged, it can make a clicking noise when the vehicle is turned or accelerated.
If you are experiencing a clicking noise when backing up and turning the wheel in your Chrysler Pacifica, it is important to have your vehicle inspected by a qualified mechanic to determine the cause of the noise and, if necessary, get the problem repaired.
