Crazy alignment problems

you will never get anywhere with the wheels loaded. they have got to be able to slide/ be unloaded.

get two jacks and put them under the lower arms as close to the wheel as possible. this is to to just get the wheel off the ground. It'll droop slightly but that doesn't matter at this point. get a piece of chalk and mark the tread in the middle on each tyre (tire :)). Move the wheels so the mark is at the rear to a point where a tape measure will go between the two wheels under the floor. measure then move the marks to the front (you will need an extra pair of hands). remeasure and hopefully you will have a 1/8 inch shorter measurement at the front. if not adjust the tracking.

this is only for a quick check and not ideal for proper adjustment.

if you still have a problem after this then obviously there is a major issue. the only way to find out is measure camber, caster and bump steer which will point you in the right direction.
