it looks to me like its either had a big crash or when you have greased the bearings the bolts have either been too tight or slack !
I have always been a GG rider up until 2 years ago , when I did a large amount of research on TRS and only heard good things . I bought 1 have riden several large foreign events at an s2 standard done plenty 2 /3 days events nationals etc so at 2 years old I have just exchange it for another TRS having not had a single problem , I would say yours unfortunately is a one off - I would check the shocker is working correctly before rebuilding .
