Technician A says a pitman arm should be removed using heat. Technician B says a pitman arm should be removed using a puller. Who is correct?

A pitman arm should typically be removed using a puller because of the potential damage that can occur if heat is applied. Heat can weaken the integrity of the components and may affect the surrounding areas by causing warping or affecting other parts of the steering system. A puller is designed to safely and effectively separate components without risking damage, making it the appropriate tool for the task.

Using a puller ensures that the pitman arm is extracted without applying excessive force or heat that could compromise its structure. This technique minimizes the risk of damage to the steering gear or other connected components, facilitating a safer and more effective removal process. Thus, the correct answer is that only Technician B is correct in advocating for the use of a puller.
