pulled the rear flange off and man was it loose, checked the shaft and it seemed fine, nothing wrong there no play or anything in the shaf. Pulled the seal but noticed that i got the wrong seal from marlin and there sending me a new one.
Also while i was at it i went ahead and checked all the bolts on the front end, i noticed that the u bolts were only torqued to 20ftlbs and the book says 70-110 so i was a little off there. so tighnted that andhopefully that will fix my issue.
Does anyone know where i can get another transfercase flange nut?
