Plenty on the internet....the middle shaft should have both journals set in the same position.

To add further confusion Dave there are three UJ's on steering if later cars. The one nearest steering wheel to accomodate vertical adjustment of steering position. On my car the yokes of second two are not aligned having an offset around 30° and it steers fine with the help of factory standard EPAS below, as fitted to Toyota Aygo, Peugeot 107 etc. This differs from the requirement for a transmission propshaft

There is a useful pdf download available here explaining phasing of UJ's on a steering shaft.

Whilst the yoke offset found on my car aligns with article, turning steering at wheels to accomodate greasing whilst on ramp I can still feel steering wheel accelerating/decelerating a tad.
