What is the recommended method for hoisting a vehicle when checking ball joints?

The recommended method for hoisting a vehicle when checking ball joints is to hoist the vehicle by the frame when the upper control arm supports the spring. This technique is essential because it allows for a stable and secure lifting of the vehicle, ensuring that the load is evenly distributed across the frame. By doing so, the suspension system remains in its normal operating condition, which is crucial when checking ball joints, as their condition can be influenced by the angle and position of the control arms.

When the vehicle is lifted by the frame, it supports the entire weight of the vehicle properly, allowing for accurate testing of the ball joints without introducing additional stresses that could affect their performance. This method also helps to prevent any unnecessary movement of the suspension components during the inspection, making it easier to detect any looseness or wear in the ball joints.

Other methods, such as lifting from the rear end or from the tires, would not provide the same stability or accuracy in assessing the suspension system's condition, as they may not evenly distribute the weight or could alter the position of the suspension components. Similarly, using a hydraulic lift on the engine block could lead to an unbalanced situation that might distort the suspension setup, ultimately complicating the inspection process. Thus, hoisting the
