Hi .
I have a 2016 2.0 ford transit custom . Originally i had a leak on the rack which was replaced with a non genuine part but for that van . The steering was heavy and whining so they fitted another rack which was exactly the same . They then said it must be the pump so that was replaced , still the same but steering okay with a whine at higher revs . Yet again said it must be a dodgy pump so another pump was fitted . It’s really light but as soon as it goes over 2/2500 revs it whines again and becomes lumpy especially to the left . Also replaced the reservoir and feed pipe just in case .
Anyone have any ideas ? No leaks and not loosing fluid
