A couple of weeks ago I went out in my Mondeo, as I got to the end of the road to turn left I found the steering to suddenly be very stiff. Turning right had been fine. I carried on and didn`t notice anymore problems. This me a bit so I took it to my local garage for a check over. They couldn`t find a thing wrong. I left it with them again a week later expecting them to fit new top mounts, but they were not needed as everything was as it should be. I have had no more problems since the original occurrence and the car drives perfectly normal, even my wife says t is ok and she does 250 miles a week in it.
Any ideas what could have caused this? Would it be worth flushing the PAS system? Possible column UJ ( but why have I not experienced any more problems?) even the garage were baffled.
