Fair point!

I think it came about when I asked said local Vauxhall 'expert' why the Cav's and Calibras had to rotate the tyres around so much to prevent transmission damage compared to Ford's 4x4 cars. So it must be due to the transmission on them being at a stretch as standard so if front or rear is running less tyre drag than the other it can damage it?

Anyway - thanks for the comments - I'll add the videos this evening (all going well with the editing!)
