Re: Trailer heavy enough?
Ok so the first thing you need to do is verify the axle rating sometimes it is stamped near the center of the axle itself you can also measure the bearings but I'm not sure how, some one else here will know though, then I would do a full bearing service and inspection as well as a complete inspection of the steel on the trailer and any suspect areas repaired, then maybe do a test run around the block and see how it feels before going all the way. There are a few things that concern me but we really need better pictures to go anywhere else. The coupler I would like to see and the main beam dimensions of the trailer, the age if possible.
Verifying the ratings of the axles will tell us if you have enough axle to carry your load from there we can move on, 3 2500LB axles are almost there but your still overloaded, it might be a better idea to upgrade the 3 axles to 3500Lb then to add a fourth 2500 Lb axle, I have to believe 4 axles is going to make you stand out like a sore thumb to the popo, you don't need any more attention!! That's going to be quite a load!!
