The Mono (single) Leaf spring's that came on my DHM trailer standard broke this weekend (the 2 rear leaf's on my tandam axel trailer). My trailer is 2 year's old and in no way should they have broken this soon. I don't tow with weight or Jump my boat & trailer ect, I even had a Extra because a friend with the same boat/trailer had recomended a spair because one had broken on him leaving him at the side of the road for Hrs. I up-graded all 4 leaf's from the Single Leaf to the tripple leaf that cost $200 at a local trailer suply store. This jacked up my trailer about 1 inc. But it seems to tow nice.

On Monday when DHM was open they said sorry, and they gave me the Ph # of the company that make's the Leaf springs he said there was a older Recall on the single leaf spring's????? I had never heard that?. The company that makes the Leaf's was nice and said that they would send me out 2 New up-graded tripple leaf spring's. Free"( I guess I will use them as spairs Just in case!

You Might want to check your leaf's before the next time you head out My'n broke right in the center of the Leaf where you couldn't see any type of crack starting ect. So I dont know how your going to check??

The first photo is of a "NEW Un Broken Mono Leaf"
The second is of the New Installed Tripple Leaf's you can see how the tripple leafs would take the load much better.

Take a look at your leaf's my'n broke right in the center where the centering bolt goes threw.

Let me tell you Doing this Job is a "Black Whore"
all the "u bolts" have there threads powder coated Black, (woop's) This makes taking them off a Beeeeotch. You need some serious tool's for this job. Big wrenches and deep impact sockets. My friend had a Impact driver and this was still was still hard, We were VERY LUCKY we made it all the way to the lake and after we launched the boat we discoverd that the Leaf's were 99% broken, They haden't fully let go just yet a few more miles and it would have been all over, With the boat off the trailer and in the water and a clean well lit place to work on the trailer it made it much easyer to change the Leaf's. I couldn't imagine having to do this job on the side of the road with the boat on the trailer. Doing this job makes a flat tire with no spair stuck on the side of the road a walk in the park.

Even though you upgraded to the triple springs, still be sure to keep an eye on them!!!
I have been through three leaf spring packs in the last 5 years. I have a Ski Nautique with a double axle trailer, no extra weight. This is a small boat for the trailer, but it still breaks springs now and then. The triple leaf springs will break right in the middle like the picture above shows.
I do put a lot of miles on my trailer as all the good lakes are many hours of driving away.

Mateo What Kind of Leaf spring packs are you going with. The ones that came on the trailer I think are call Unique Function Products or UFP for short

UFP said that if the U-bolts are not tight they will and can caue the spring's to break. I say BS my u-bolts were very tight.

Grant, does your trailer still bounce like crazy?
Old    whitechocolate            08-06-2003, 5:43 PM Reply   
No I think it ride's Smoother, Even though it has 2 more springs than the stock, The new ones are thinner, So I think the springs move easyer and stop it from bouncing as much

Sorry to hear about your spring problems. When I first got my trailer I wasn't too sure about the rubber torsion axles, but after three years of trouble free service and hearing about all the issues with leaf springs, I'm glad I have them. Here's a picture and link with information on the rubber torsion axles if anyone is interested.

IMO: Never take delivery of a new boat with mono leaf springs or Carlise tires. These problems have been out there for years on all types of trailers.

Thanks Grant, I am going to take a look at the VIN on my trailer and do some preventative investigation before I am stuck on the side of the road somewhere.

Grant, I don't know what brand the leaf springs where, I just pick them up as needed from the local trailer supply store.

Dan, that sure is a pretty pink trailer you got there
