Replace coil spring
You have to remove them - that "block" is the upper strut-to-body mounting section and serves as the upper seat for the spring as well as the anchor for the top of the strut. You need to take those four 17mm bolts out, as well as the rear upper sway bar bolt, the upper control arm bolt (at the top of the hub), and the bottom bolt on the strut, where it goes through the lower control arm. You'll then have to compress the spring enough to take the bolt out of the "block" (it goes through sideways, and I believe is 19mm on the bolt head as well as the nut). At this point, you can slide the spring/strut out of the block, decompress the spring, pull out the strut, and install a new spring over the strut. Recompress enough to get the top of the strut visible through the anchor bolt hole in the block, rebolt it, decompress the spring, and reinstall the assembly in the car. Usually when you go to reinstall it, the bottom of the strut is not angled quite right once the top four 17mm bolts are back in and the block is secured to the body. I put a large screwdriver through the lower strut bolt hole at the bottom of the strut and use that to turn it, or I grab the weld near the bottom of the strut with large ChanneLock pliers and turn it until it's aligned with the control arm properly. Once it is, put the lower bolt back in, rebolt the control arm and sway bar, and you're good to go.
Note - this job will not affect alignment specs - you don't remove any bolts used in aligning the car, so that's not a concern when doing this repair.
