Re: Leafspring bolts
Thanks for quick reply I just painted trailer yesterday and doing bunk boards today. Since I have the room now with boat off want to fix these now I wanted to put nylock nuts on but not enough treads on bolts and the washers same problem. I will try lock tite on them with lock tite should I just snug them up and maybe add a half turn to them? Thanks again.....
Per the above post and your pic, I am guessing your talking about the spring eye and shackle bolts.
You do not want those to be "as tight as possible" if they are those points will not want to swivel. If there is not enough thread to engage the nylock feature of the nuts, then yes you could use some locktite on them.
Or use a cold chisel or punch to upset a thread or two a little bit at a point after the nut is started good.
The axle to spring pack u-bolts if new, might have stretched a bit since first installed. And/or the spring plates might have bowed a bit or got bumped and bent a bit. And if the u-bolts and nuts are hot dip galvanized and installed new the soft galvanizing may have given way in the area where the nuts engage the threads of the ubolt. And are thus not as tight when first torqued.
