The SVA manual asks for "a degree " of self centring when driven at 10mph+.

What exactly does this mean ? Is it when driven in a straight line , cornering , or both--.

Phil , you will find that when driving in straight line the steering is "centered". self centring means that steering will return towards straight ahead if the steering wheel is released. find somewhere where you can try this on your everyday car , you will see what I mean . Rusty

The SVA tester drives the vehicle with full lock on (no matter which as he tests both sides!) at approx 10mph. This way when he puts the wheels on full lock and he lets go of the steering wheel it "attempts" to return to centre (straight ahead position). He then repeats this on the other lock. If it attempts to return to centre it's deemed a pass.

We toe'd out our wheels 5degrees or more.

Thanks for the info ------finally do they test centering when the car is going straight and the wheel is moved off centre only a little

thanks , phil

They didn't on ours

Only tested one side on mine

Thank god

I'm going to visit my test centre -Llantrisant (cardiff) to see if they can give me advice on this and a few other sticky points -----I'll feed back next week if any relevent info comes up

Thanks for the replies ,

Go find an empty space to play in, pump you tyres up to about 25-30psi and then adjust the front toe. you will probably find that with the right amount of toe the car will have quit good centering but handle rather strangly.

I did thi for SVA and it was commented how much "feel" the car had when centering, i then brought it home, set the tracking back to normal and let the tyre pressures down.
