Good points by StarTech. There was a number of problems with those Hustlers and the main one was the brackets holding the two hydo's together and in alignment was weak and the bolts and nuts loosened up and fell off.
There are two additional brackets that I installed on my Raptor SD54. Here is a picture with part numbers. I have had no more problems after installing these two braces. I also used Loctite as a backup but Hustler did go to Nylock nuts which were a big help.

The lower cross brace is massive compared to what came on mine from the factory.
