Look below, you will see you are good to go on the rears, but they have installed the wrong ones in front. They probably installed rears in the front too. This is a typical way of achieving 3" of lift in Rovers, but they didnt do it right. If you cant tell what they are, order two new fronts from the chart below to match them correctly. Go on the ExpeditionExchange website(https://www.expeditionexchange.com/ome/indexsprings.htm) for good explanation of all the possible combos for OME springs. The vibration is from the horrible pinion angle you have up front and it will lead to ujoint failure eventually.
