set them all to 30psi (which I wasn't so sure about). My user maunal quotes tyre pressures as about 34 to 36 psi, where as his wall chart shows 30psi. Which is correct?

This method is correct for 4 wheel alignment. You check pressures, put the lasers on with the wheel set straight. Then you check the measurement. You need to set the marks on the rear the same on each side, this ensures that the car is running straight, then you adjust the front equally each side to get the Toe right. Ensuring that the rears are still equal. On the fronts you add the measurements from each side to ensure that you are within the tolerances given for the Toe. If everything is right you tighten the track rod lock nuts back up and test drive to ensure it drives true.Originally posted by kevster:
[qb]He centered the steering wheel and then locked into position with some kind of clamp, he then checked the tyre pressures, he then mounted the lasers on each wheel and turned them on. He then adjusted the alignment of the front wheels such that each one was off set by the same amount relative to the targets on the rear wheels. I presume there is not much else he could do as the alignment of the rear wheels is not adjustable (I assume) and I'm not sure if you can adjust any other form of miss alignment of the front wheels???

and what percentage of a turn is supposed to be measurable??? With all due respect, i was trained by professionals at great lengths over 2 years about all things cars... And i personally paid a lot of attention to the geometry side of things. After all, a car that does not drive straight when expected, is really no good to anybody!Originally posted by Neil(CS2.3T):
[qb]Things are getting blown well out of proportion here! As long as you have an equal number of turns each way there is no cardinal sin committed. From what you put down, kevster, the tracking has been adjusted properly. [/qb][/b]
I would tend to agree with that.... except that Kevster starts off his post by saying he has just had new wishbones fitted.Originally posted by saabz2000:
[qb]Ther are normally only 2 main reasons for this to be wrong.... somebody has bu99ered up the lock by winding 1 track rod all the way in, and the other all the way out. OR, and this seems likely.... seeing as the 'setback' (difference in distance between the front and back wheels) differs from side to side. You probably have a bent steering swivel member ( wishbone ). [/qb][/b]
