For oil changes and motor work, I use steel drive-on ramps.

For access to the entire undercariage, after the ramps are in place I use, in addition, jack stands placed under the subframe carrier to chassis mount.

The differential is one of the strongest parts, so I jack the rear from there.

For setting the driveshaft nut and center carriage bearing mount, as the car needs to be on its wheels, I use an additional set of ramps under the rear wheels, placing them by jacking the rear of the car after the front wheels are in place on their ramps. This is only because I don't have 4K or the space for a lift.

I agree that a rubber jack pad or piece of 2x4 are good ideas, however, the front cross member is like that of a truck, so direct contact with the jack dish is fine.
