My last set of tires wore away completely on the insides long before
the rest of the tread was gone. I was talking to one of my buddies and he had the same problem. I'm thinking the axle develops a bow in it. So earlier this spring I left the floor jack under the middle of it with it jacked up some. Too early to tell if the new tires are wearing the same or not. Can't measure the distance between them at the top and bottom cause the street and the boat are in the way so I don't know if the camber is ok now or not. Anyone else have this problem and do any investigating? |

You can check by raising the tires off the ground spin the tires and make a scribe mark on the treads all the way around. The scribe must be stationary while you are doing this. Measure the distance between marks top and bottom. The difference is camber. Measure the distance between marks front and back. The distance is toe. 0 to 1/4in is good for toe in. I'm not exactly sure about camber but there should be some negative camber. |

A 4' level should do. You ought to be able to tell if it's bowed up a little. |

That seems to be the most logical explanation since I have the same wear problem on both sides. A bent axle would not likely be bent symetrically. Nor does it seem reasonable that the toe would change on both sides. Question is will my parking it with a floor jack under the center bent it back over time. Also seems that it would be better to store over the winter with jack stands under the frame. |

Cause it bows up about 3" in the center when I lift the entire trailer and boat from the center of the axle with the floor jack. You're saying that doesn't matter, that's not enough to bend it any. Even if I do this for cummulative months? |

Did I understand you right - it bows a full 3"? There is no way it should flex a full 3" and that is probably your problem.- Hide quoted text - - Show quoted text - No, you don't understand. It only flexes up when I put a floor jack under the center of the axle and jack it up till it's trying to lift the whole thing off the ground. It's only a 2" square tube axle with a 19' V8 boat on the trailer. 2" square axles can be used up to 3500lbs. The axle between the springs normally doesn't have any significant load. The load is all on the last 4" from the springs to the spindle. I'm doing this because I'm thinking that over the 20 yeasr of it's life it has slowly sagged in the other direction. Now I'm trying to make it sag back the other way but hopefully a bit faster since I'm putting a lot more stress on it. |

If it does go back it will have been bent in two directions and the metal will be weakened at the bend point and will soon bend again. Three options stand out. Get a new Axel weld support into old axle once it is in place. Leave the bend in the middle and do two proper bends in a "unbent" area further out from the middle of the axle on each side... -- Rowdy Mouse Racing - We race for cheese!- Hide quoted text - - Show quoted text - It's not visibly out of straight or visibly bent anywhere. I'm not trying to bend it at one point, I'm trying to bend it all across the axle. So I'm thinking we're talking about nanometers of strech at any one given point on the axle. I'm having trouble seeing how that weakens it any appreciable amount. Not to mention that if I take it to a shop they are just going to "bend" it as well. Since it's galvanized they can't heat treat it. So I think your "weakened" theory doesn't hold water. |

Ah - I get it - you're right, I misunderstood what you said. Gotta wonder though if, and I think this is what you were getting at, it's bent in the other direction. *Have you put put a straight edge on it - like, say a carpenter or mason's level on the axel? Since the tires wore out on the insides equally it would seem that the camber is negative. Since it's 20 years old and has sat on the tires with a boat on it that whole time I'm thinking it developed that negative camber slowly over time due to the load. At first I though maybe my springs were rusted together increasing the load but I loosened one and the leafs are free. |

I'm not going to try to calculate the difference in length from the top to the bottom of a 90" by 2" rectange whos long sides are 3 degrees out of true but I'm guessing it is pretty small. A difference that makes no difference is no difference. Or by your analogy a teaspoon of water in your bilge isn't going to change anything. A new axle is $300. Since it's galvanized welding on it would not be a very good solution. |

Now I'm trying to make it sag back the other way but hopefully a bit faster since I'm putting a lot more stress on it. Ah - I get it - you're right, I misunderstood what you said. Gotta wonder though if, and I think this is what you were getting at, it's bent in the other direction. Have you put put a straight edge on it - like, say a carpenter or mason's level on the axel? Since the tires wore out on the insides equally it would seem that the camber is negative. Since it's 20 years old and has sat on the tires with a boat on it that whole time I'm thinking it developed that negative camber slowly over time due to the load. 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. |

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? |

But, would attaching a couple pieces of strong angle iron with bolts and nuts add a lot of strength to your axle? Seems to me you could do so relatively cheaply. -- John H All decisions are the result of binary thinking. |

Does galvanized welding really exist or are you referring to an axle galvanized after it was welded? Welding temperatures are higher than the melting point of zinc, and zinc is consumed or highly altered during any welding process. It also produces toxic fumes that cause weld fume fever. Galvanizing is done after welding, either on virgin metal, or a redip after welding repairs. Zinc melts at 419.5, and iron at 1535. Steel is iron with other elements added, and can be heated to over 2,000 degrees for tempering purposes. At that temperature, the zinc would be burned off, or assimilated into the metal.

Thanks, that's good to know although I've been trailerless for several years now. They are actually on the service road north of Crystal, East end but it is a great resource for all sorts of hot dipped galvanized hardware at a good price. It is a whole lot cheaper than the "dock/boat lift" store They are pretty good about letting you graze through the bins and collecting a bag of bolts, washers, plates or whatever. Then you take it to the office and pay. They like cash. ;-) I assume you know about this place on Hanson Street? http://www.industrialmarine.com/ They have a good selection of hardware also - galvanized, stainless, and maybe some bronze as I recall. They also sell very handy "briefcase" style tool kits at a good price. The amount of stuff in their back room is enormous. |
