I bent my front rails a bit lifting the car with 3 wheels off the ground to slide a jack stand under. A length of 2x4 would go a long way in distributing the force, not needed if servicing only one wheel. If you are going to jack the front using the cross member (which is not a listed jack point btw) use some wood for distribution and place on jack stands at the proper jack points. This was the technique I used jacking my Citroen CX (the most beautiful car in the world)
