Wheelbase Setback

[rayleask]

Hi. I have just brought a Fusion 2004 Automatic. Despite all efforts over the last 10 days I cant find anything wrong with it. It drives fine, it goes in a straight line even when braking hard with my hands off the wheel. I can find no evidence of accident repairs.

A brother-in-law then suggested measuring the wheelbase both sides. We found that there was a 5mm difference. Checking my old Fiesta that also had a 5mm diiference. Having had that from new I know that it has never been involved in an accident. Another later Fiestas I checked had identical measurements. Apparently this difference is called "setback".

Does anyone have any knowledge of this setback thing? Even better has anyone actually measured their Fusion wheelbase and seen any difference?

Thanks, Ray
