I ordered new spring lines (2 pack) as well was 2 new springs. I was startled that the parts arrived in less than 48 hours using standard shipping. I went ahead and ordered the springs, even though I assumed they were OK, since I was going to the effort of replacing the lines. I was glad that I did. When I accessed the spring mechanism, I discovered that the plastic frame that holds the spring in place was cracked and the new springs have an improved metal clip that secures to the frame in another slot in the frame. I followed the instructions in the DIY video with no issues. The entire process took about 90 minutes to replace both spring mechanisms. Glad to save the cost of a service call.
