Where should the jack stand be placed when replacing a right rear lower ball joint?

The proper placement of the jack stand is critical for safety and stability when performing maintenance such as replacing a right rear lower ball joint. The correct choice of placing the jack stand under the frame on the right side ensures that the weight of the vehicle is supported directly over a strong structural point. This positioning protects both the technician and the vehicle, as it provides a stable base to work from while replacing the ball joint.

Supporting the vehicle’s frame on the right side is also crucial because it keeps the suspension components in the right position during the repair, allowing for easier access and minimizing any potential flex or movement that could occur if the vehicle was supported incorrectly. This is particularly important with suspension work, where precise alignment is needed for parts to function correctly once the repair is completed.

In contrast, supporting the vehicle from the left side or under the left rear control arm would lead to an unstable setup that could risk the vehicle tipping or shifting, creating a hazardous working environment. Therefore, the choice to place the jack stand under the frame on the right side is the safest and most effective approach for this type of repair.
