its ok.... they make 3 different widths of light trailer springs, and 2 different widths of hangers, and although the hanger you have is wider and looks odd the way its fitting, it will work just fine.... it will outlast the spring that its supporting.
its unlikely the hanger is cracked near the weld, but its worth checking....
if you start nit-picking the suspension under these light trailers, you will find the entire suspension system a bit sketchy....
very thin nylon pin bushings, spring hangers that may be too light for the actual load the trailer, spring retainer plates that the ubolts go thru that are too light for the torque rating of the ubolts used, and various other deficiencies that if redesigned could make the suspension ride better for longer.... and this doesnt even include issues with the barely adequate brake system....
but, the suspension being redesigned isnt going to happen, so we just need to inspect and service the suspension and brakes about every 40,000 miles to insure its all holding together and the bushing arent too badly worn....
or you can fix it to look like you want it to..... but it wont ride any better, or last any longer, and you still should keep up on the inspections to insure problems dont develop elsewhere..
