At first I though maybe my springs were rusted together increasing the load but I loosened one and the leafs are free. Here's a bit of experience I had with Dexter Axle. I bought an axle that had no camber and no toe. Sent that one back and got a new one with good camber but had toe out. Third axle was the charm It had acceptable camber and toe in. Conclusion: Even reputable mfrs. don't always get it right the first time. You should find out for yourself if your axle has a bend problem. If it does, contact a axle/spring/frame shop and see if they will fix it for you. Ask them if the bend process weakens the axle. Maybe it needs to be re hardened after bending. The frame shop will know. |

Plus shipping, the extra $15 handling, and then you're getting to the $300. |

I had a sailboat with the old original 1986 trailer. The trailer was rated at 1200 lbs, which is what the boat hull was supposed to weigh leaving the factory. Later found that my boat actually weighed just over 1700 lbs. In my case...it was the tongue that had developed a downward facing bow. If you know what the rig weighed new, I'd take it to a weigh station and see what it weighs now. Is that trailer up to the load after long service? |
