The power steering pump is making an awful groan or grinding noise. Whats the problem?
This could be caused by two problems. First, the pump could be low on fluid so its “cavitating” – when bubbles form in the fluid low pressure area and collapse in a higher pressure area of the pump, causing noise, damage and a loss of capacity. Cavitating is not good. If you continue to run the pump with this problem if will wear out very very quickly. Second, your pump is already worn out. A worn pump will not fix itself. Time to place the pump and check for any leaks in the system (such as the rack).
