Full Answer

If power steering fluid continues to go low, check for a leak by looking underneath the vehicle for wetness. With the transmission, if low fluid is not the culprit, it could be severe wearing of the bearings and gears of the transmission system. To look for wheel bearing wear, look at the tapered rollers because they become barrel-shaped during the wearing. The bearings will not have a polished finish, either.

  • Q:

    Why does my car make a popping noise when I turn?

    A:

    The most common reason for popping noises heard while making a turn is a defective or wornout constant velocity joint. The driver might only notice the popping sound while making turns in a specific direction or when the turn is especially tight. The CV joint pivots with the turn of the vehicle's wheels, so a loosening of the joint might only be noticeable when the wheel is turned all the way to the right or left.
