Ford Mondeo MK4 power steering faults
Ford Mondeo Mk4 models often have power steering problems.
It can start with a loss of assistance on either one side or both sides. this is a manufacturing fault with the steering rack, it can lead to the piston inside of the rack starting to disintegrate and lose internal pressure. This can lead to the reservoir filter becoming blocked and this, in turn, starves the pump of fluid and can lead to pump noise or failure.
Sometimes the first sign of power steering problems will be noise from the pump, it is important not to rush to replace the power steering pump without looking into the root cause of the noisy pump, usually with mk4 mondeos the noisy pump is caused by the particles from the failing steering rack either blocking the reservoir filter and causing the pump to cavitate due to fluid flow restriction or contaminated fluid causing wear within the pump.
In order to solve these issues the rack and reservoir bottle must be replaced first, the system must be flushed and then run to establish whether the pump will also require replacement.
Replacing the pump before replacing the rack and reservoir bottle is not recommended as this can lead to the new pump failing again.
