Fix Power steering noise Ford, overflowing at reservoir
Owners of Ford Focus vehicles may experience noisy power steering, an empty power steering reservoir, or a reservoir that’s overflowing. The problem is caused by air entering the system, whipping the fluid into foam, and then overflowing. Air can enter the system at any connection point.
Start by checking the crimped connections on the power steering hoses. Look for any signs of fluid leak or dampness. Then check the boots at the rack. The inside of the boots should be dry. If there’s fluid inside the boot, the rack seals are leaking and the rack must be replaced.
Most shops that have worked on this problem have discovered leaks in the power steering return hoses. Once they’re replaced and the shop performs an air bleed procedure with a vacuum pump, the problem goes away for good.
