I've got a horrible problem with my steering. Had to drive it home real slow and park it up now. It occasionally knocks and then jams solid either right hand or left hand steer - almost as if something is jamming in the rack (something lose?). Just backing-off the steering one way and trying again seems to un-jam it and I could carry on manouvering. I'm sure its a positive jam - its not as if its sudden loss of pump pressure or power assist, I reckon. Anyone got any ideas? Thanks.
