Jacking point damage

We frequently see the underside of XJSs damaged – sometimes severely – as a result of incorrect jacking. Unlike most modern cars, the XJS sills are not designed to take the weight of a car on a jack, and special jacking points are provided which are part of strengthened areas. Most owners are aware of this and use a jack correctly. But some garages are unaware, and use the sill seams like they would on a modern car. This causes the sill the bend alarmingly, and can be expensive to repair. Our advice is to make sure that the technician working on your car is aware of the jacking points. These are, incidentally, just forward of the rear wheel, and just behind the fronts. They are identifiable by having a small steel ‘bobbin’ which should be used to engage with the normal roadside jack.
