How we handle wheel alignment at Hackbridge
The bay matters as much as the equipment. An alignment rig can only report the truth if the car is sitting level and square, so the ramp is checked and the car is settled on its own suspension rather than hanging on the jack. Tyre pressures go to the placard figures first, because a soft tyre changes the rolling radius and skews the camber reading before a single measurement is taken. Targets are clamped to the rims and the car is rolled back and forth through a compensation routine, which teaches the equipment to ignore a slightly buckled wheel instead of treating it as a geometry fault.
Before we adjust anything we get underneath with a pry bar. Play in a track rod end, a tired lower arm bush or a wheel bearing with a trace of movement will all put a setting out again within a week, so if we find one the alignment stops there and you get a written quote for the repair. We will not dial the good angles around a bent component either. If a strut has been pushed back in a pothole and the caster is out on one side, correcting the toe to hide the pull only makes the tyre wear worse, and we would rather say the car needs a part than sell an adjustment that papers over it.
You see the screen at the start and you keep the printout at the end, with the red and green figures for each angle side by side. The published alignment price from £59 covers the four-wheel measurement and the adjustment of every angle the vehicle allows. Anything beyond that, a seized track rod that has to be replaced or a camber bolt kit, is priced in writing and only fitted once you have said yes. If the measurement shows the car is already within tolerance, we tell you that too.
