At slow speed and more or less stopped steering wheel pulses from side to side. Wheel alignment etc seems OK. Perhaps this is a power steering problem? Any ideas or experience with this problem. Car is a 95 XSI with 170000km. Otherwise runs fine.

                        Make sure that; 
 
- the wheel nuts are good and tight 
- the tyres have no damage or bulges in the sidewalls 
- the wheels aren't buckled (jack the car up, and have an assistant turn the wheels while you look from the front)
