Product review (5 stars): Simple job, could be done in 30 minutes or less if you have the right tools.
Fairly easy replacement for your leaky LG washer.  Taking apart the washer was easy as well as removing and reinstalling the front spring.  The inside spring on the other hand was tricky.  The loops on the spring that you need to insert your DIY or other tool into are small so it's difficult to keep the spring on the tips of your tool; but it's doable.  I didn't buy the LG tool, but instead bought a different one that has a knob on a threaded shaft that's used to extend the springs.  I did everything myself with the exception of reinstalling the inside spring which I had someone with a second pair of needle nose pliers help me to hook back onto the spring.  Took me two hours total, about 1 hour of that was waiting for an assistant to arrive.

A video on Youtube from RepairClinic.com walks you through each step; makes for generally easily replacement.  While you have the front cover of your washer off, also check the other hoses, mainly the drain hose which seems to fail occasionally (as reported in some appliance forums).
