I can't say that I did,I've replaced the trans mount but still there,I just kinda gave up and ran with it,it has not gotten any worse. However I have replaced the whole center section this winter with new unit including case. Looked over the one removed did not see anything that stood out.My simple spidy sense said noticed it after the 4.10 went in thats where it should be but just did not want to change it out but now it is, if we get back to racing with the shutdowns and such.
