Hi had my 4x4 saff for about 2 months now and noticed the steering has got very heavy! also if i pull out of a tight junction or corner it wont self centre just wants keep going round. It is worse when the engine is cold but doesnt get much better when warm. The power steering fluid looks clean and is bubbling so the pump must be working. There is no leaks and i have blead the system by going lock to lock but it is no better. Hope there is someone out there who can help.
