Hi. My first post here

I have similar problem, but it’s not a knocking noise. When wheels are straight and I try to turn the steering wheel to the left there is a higher resistance on the wheel, then a dull knock and everything backs to normal. It won’t do it in any other position, just when wheels are straight. There are no knocks or leacks from the system, fluid was replaced with Ford one and level is ok.
I’ve suspected suspension but it looks like it’s coming from the steering rack.
What about the pedal plate? Do you have any photos or at least a hint how to fix it?
I will also check a steering column connections but don’t think that’s a problem.
It’ bit odd and I want to investigate it before replacing the steering rack.
Thanks for any suggestions.
