This thing is kicking my ass. Finally figured out that the original springs were open eye on one side. Found only a couple of places that had them, but got them and they fit. Then realized that my inner wheel bearing was gone...
Other side was OK and the grease looked pretty good. Replaced bearings on one side and repacked the other.
So I got my 9/16" bolts to go in the 9/16 bushings...and then found out that the holes in the trailer are 1/2".
Question then am I better off drilling out the holes in the trailer to 9/16 so that they are snug in the spring bushings, or use 1/2" bolts?
