Loose Shackle Bolts From Factory??? *PICS*
While under my brand new TT this afternoon giving everything a once over and just trying to familiarize myself with everything under neath, I noticed the nuts for the shackle bolt wasn't tightened all...

. . . my trailer came with cheap metric steel shackles. To elaborate on that, it was 5 mm thick steel (.196") but the bolts and springs are sized for 1/4" (.250") thick shackles. The result is .108" excess clearance, that is nearly 1/8 inch and might be what we see here. . . .
That .108 excess clearance is on both sides of the spring too. That comes out to .216" in excess clearance. Almost a full 1/4" excess.
No, I took that into account. There is about 1/16" clearance designed in the assembly, and the springs are made to a minus tolerance. For example; if you have springs that are -.015", the .062" design clearance, and the .054" undersized shackle on each side, the result is .185" slop. I made new parts from better steel, altered the bolt lengths and used good locknuts, giving me .040" total working clearance.
Look at how the cheap locknuts locate on the bolt shoulder when tightened, and you will see one reason why I replaced them.
Yeah, I noticed you took it into account. I just didn't get it deleted quick enough. :) I fixed the same problem with a MorRyde wet bolt and heavy duty shackle kit.
