I've just acquired a 1989 1.1 GL, 4door 205, it has 38,000 miles and is in very good condition. Couple of minor issues but steering is very heavy despite having new tyres inflated to 35psi.
I heard that if you tap one of the knuckles and use loads of WD40 while car is on axle stands it can free up steering column and lighten steering. I haven't attempted this yet but would appreciate any advice or tips on how to go about this and are there any other ways to lighten steering?
