This relates to a 3 door, 1993 diesel discovery 200Tdi
In the last few days the steering has become very stiff and won't naturally centre. This leads to difficulties cornering and a tendency to over correct.
There are no obvious leaks in the system and the drive belt is tight.
Any suggestions where to look first? Power steering pump, power steering box, steering column? How do I tell if the fault is power steering pump or steering box?
Cheers
Peter
