But, the easiest way is to stick a big piece of wood under the sump bulge and jack it up. You will possibly have to undo the exhaust pipe from the extractors.
The bulge will ordinarily take the weight, however you would of course want to watch it carefully just in case
i just been lying under my car to check the mounts, and i can see a way to change the exhaust side one, but the inlet one looks impossible! id have to remove the oil filter, and then see if i can do it. so ill wait till next oil change in 4500ish kays.
i put the car on ramps to check the diff as it had been maing awful noises, turned out to be a knackered uni joint, the 2 cups in the tailshaft side had no needles in the and was loose as a goose. and id been chirping 2nd before i put it up on ramps! geeez i was lucky it didt let go!
