There is a batch of steering racks that have "faulty seals" as i was told by my dealer - i complained of crunchy grinding noises when doing car park manouvres, with the steering going heavy at times, they checked the steering rack against thier list and its one of the dodgy ones - now awaiting dealer to phone me to get it replaced. (reminds me - must phone Ted Johnsons to chase!)
Irony of the situation is the car was fine before i had my wheel walloped by a passing bin wagon which managed to wreck the steering rack and a suspension arm, the repairs involved putting a new rack on the car - so i went from a good steering rack prior the accident to a faulty rack after the repair
