Have you weighed the rig?I have checked the tongue weight a couple of times.
You can not confirm tongue weight w/o knowing the actual weight of the rig.
It's possible the axle to coupler distance is too long for the load and the axle needs moved.
How do you know where to put the axles on a trailer? For an existing trailer, follow these instructions for calculating axle position.
Yes, my old trailer deflects quite a bit more with a #5,200 boat sitting on itAlthough, in leveling the frame of the trailer I did notice that the frame deflects a little. Maybe an inch plus over the 30’. Is this normal, I would think so.
Don't get hung up with the trailer being level, as in "level in hand".But as a result I did re-check the level with a tape measure a foot in front and behind the axles to make sure they were level.
Have yet to see a boat hooked to a tow vehicle perfectly level. Even my torsion trailers have a bit of a camber to them when hooked you
Nothing wrong with the design per say. I put 20 years and 100,000+ miles on the trailer I retired this Spring.That did seem to make the tire sidewalks pooch out the same, but it made the equalizer slant worse.
I also did an experiment, I jacked up the rear axle on one side and noticed that because of the angle of the spring, when compressed it binds against the frame and the bushing preventing it from sliding backwards. Although the the springs /equalizer sit straight without a load, when a load is applied, not enough load to cause the bind but just a bit less, the system goes wonky.
I think this validates what I think you are suggesting dingbat, that my front springs are weak. They are probably weak because, when a bump is hit going down the road, that rear hanger binds it makes the front axle take the brunt of the force and has made it age prematurely and independent of the rear axle by pushing the shorter leafs of the springs up to/ past their yield point more often…..if I’m right, this makes me wonder why this is occurring. Are the springs the correct springs? A flaw in the design?
Bear in mind that the trailer wasn't designed for your boat. You have to adjust the trailer to accommodate the boat.Thoughts?
Everything is a guess until you weigh the rig and do the math to confirm compliance. Once that is done the problem should be obvious, if one exists at all
Load rating of trailer?
Estimated weight of boat?
Actual weight of combo?
Recommended tongue weight?
Actual tongue weight?
Mfg. recommended hitch height?
Axles in the proper location?
