Pretty simple fix for a DIY homeowner with enclosed directions (and YouTube video of process). One original shock was broken and machine shook like crazy and "walked" several inches across floor. Replacement parts fit perfectly. Original plastic locking pins are a bit snug to get out and back in and one new spare is included with kit. Would prefer kit included 4 new locking pins to replace when shocks are replaced. This site had the best price for the parts, quick delivery, and I'd recommend replacing both shocks at the same time. In my case, one shock was fully sheared and only upon replacement of second did I notice it was also cracked and on last leg. Worth the time and investment for a good fix done right the first time.
