The other day we were puting the boat away and unhooking it from the hitch. As is common from time to time the tounge of the boat was a little difficult to get of the ball. Jumped on the bumper to shake the hitch loose. The tounge of the trailer came off but there was a snap we never heard before. Well upon further looking around the bolt that is on the swiwng portion of the trailer snapped right were the threads stop and the nut nd section were found on the ground. This bolt had a crack in it for some time since it was rusted through the crack and there was only a small portion of clean metal where it broke (about 1/8 inch). This is a grade 5 bolt from the markings and should have over 100,000lbs tensile strength. Please make sure if you have a swing hitch to check this bolt and make sure you do not have this issue. The nut is probably rusted solid to the bolt. Lucky for us this happened when we were putting the boat away.

Common problem on Extreme trailers 05ish. Don't know which trailer you have but...Originally posted by gman View Post
The new bolt should be slightly longer, or at least have the threads that extend a little further beyond the top of the hinge. I think the stress being on the threaded portion of the bolt contributes to early failure.
It happened on mine...i think I had a thread, but cannot find it with a quick search right now.Be excellent to one another. -

After reading these types of threads I put a new grade 8 bolt on my trailer.2009 RZ2, PCM 343, MLA Surf Ballast, Premium Sound.

Tall: Do you remember the name of the place that we bought the replacement bolts? I think that I need to write it down somewhere for when it breaks again.Originally posted by talltigeguy View PostComment

I got mine from Ace Hardware. Make sure its grade 8, its stamped on the top of the bolt. I keep a spare in the tow vehicle too.2009 RZ2, PCM 343, MLA Surf Ballast, Premium Sound.

Anyone know where you can get a locking pin for the swingout tongue? My buddy has one but it came on the trailer and the dealer doesn't sell them.Comment

I would think any true value or Ace hardware store would have them?Last edited by TeamAllen; 09-13-2011, 02:03 AM.Mike Allen, Tigé owner since 1997Comment

The trailer is a SBT (Sport Boat Trailer). I looked at Home Depot and also at Kragen. Neither one of these carries the right bolt. Will look at LOWES and other places today.Comment

Timmy I don't know if you have Big R up your way but that would be another place to look.Originally posted by Timmy! View PostComment

Never heard of Big R. There's a place called Murdoch's (farm/ranch store) over in Westminster, might try there.Comment

Got a grade 8 bolt that is 7 inches long and is 5/8. Found it in a small local hardware store. The broken one I gave to our root cause group that will perform a complete analysis on it as to cause of failure, determine alloy, hardness, country of origin etc. Hope to have results in a few days.Comment
