G'Day del,
Joel has the right idea there, but the rod shouldn't be moved from its original position on the tyres & the car rather rolled forwards to make the measurement in the second position. In an extended discussion on wheel alignment (it was probably one of the postings before Dale changed servers) I got my wrists slapped by Marco for suggesting that the only correct way to measure the toe-in was across the centre line of the wheel. This can be done but the toe measurement must be adjusted accordingly. Marco referred to Ford bulletins where they used a spring loaded gauge similar to the curtain rod with about a 6" length of chain attached to each end. The idea was to fit the gauge between the front wheels ahead of the axle, then roll the car forwards or backwards until the chains just touched the ground, the gauge was then zeroed & the car moved forwards until the gauge was to the rear of the axle with the chains touching the ground then a reading was taken. This will give you your toe-in if the measurement at the rear is greater or toe-out if the measurement is smaller. The reason for not moving the gauge is to avoid any incorrect readings due to wheels running out of true. A much easier way which was also put forward is to jack the car up & spray the front tyre treads white or chalk them whilst spinning the wheel, then with the wheel still spinning, scribe a line on the centre of a tread. Drop the car down & roll it backwards & forwards once or twice, then measure the difference front to rear at the same height above the ground. If I remember rightly Marco has a portion of his web-site devoted to this subject.
