My power steering for whatever reason will not return to centre after cornering. It feels light and the power is coming in to help make steering lighter, but i have to return the wheel to centre. The car is a 93 Lude.

 

Caster is what determines how fast the wheel returns to center...I don't why that would be a power steering problem. Unless it's really hard to turn in general, you just need to an alignment and get the caster in check.

 

Caster? Never heard of that, i will check out.

 

Yeah, its the 3 things they do when you get an alignment: camber, caster and toe. Caster is adjusted with the radius rods and bringing the wheel closer or further (horizontally) fron the center of the wheel well. I don't know would cause yours to be off, but it can't hurt to check

 

Generally caused by catching the kerb whilst parking, it can knock it out of adjustment slightly, WATCH THE ALLOYS
