Product review (2 stars): Careful - this may not be the spring tool you want!
This tool is for removing the spring clamp for LG front loading washing machines. There are two clamps: an outer one (which secure the boot seal to the door frame) and an inner one (which secures the boot seal to the tub). While Amazon (and LG) refer to this tool as the INNER spring tool, it really is for use in removing the OUTER spring and will NOT work on the inner spring. As pointed out by others, the outer spring is actually fairly easy to remove without a tool; the inner spring is almost impossible to replace without it.

This is the tool you want to remove the INNER spring:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/LG-Electronics-383EER4001A-Washing-Machine-Outer-Tub-Spring-Removal-Tool/dp/B00AMF8HF8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">LG Electronics 383EER4001A Washing Machine Outer Tub Spring Removal Tool</a>. Note the STRAIGHT arms. That's what you need. It even works to replace the outer spring clamp as well.

There is a very helpful video on YouTube by RepairClinics detailing how to remove and replace the boot. Having done it, though, I can tell you it was one of my lesser favorite fixit jobs.
