Since the machine had all 4 identical suspensions, it took me a while to find out it takes 2 different couple of suspensions for front and rear. This site was very helpful cross referencing their older and newer numbers and also had very decent prices compared to the competition. The repair was challenging because of the new springs tension while trying to push them over the top holes and lock them up with the respective blocks. Especially the rear ones had very little clearance with the above dryer and my hands are pretty big. I couldn't have done it without the help of an assistant. The stack had to go all the way down on its back and the room was tight.
