Front struts are easy on a caravan and do not require a front end alignment when done as long as you don't change the tie rod ends when you do it . There are tow bolts holding the strut at the bottom and 3 on top accessed through the engine compartment. If your only replacing the strut then you will require a spring compressor as you need to compress the spring to remove it safely This video will help
