4seasons When I had a shackle flip like that I had to put some weight on it to get it to flip back. I drove my skid steer all the way forward on the trailer while it was hooked to my truck. Then I backed the trailer's front axle on a hump to further unload the rear axle. Finally I used a floor jack to lift the flipped shackle on the spring side until it popped violently back over. You definitely don't want to be under the trailer or have any body part near it when you flip it back. This includes prying with a long screwdriver ir crowbar because when it flips it will fling that screwdriver into you (or a tire).
Mine had flipped from crossing rough terrain with an uneven load. Because of this I am planning on using slipper springs on my next trailer build. But that is just because of how I use my trailers, the shackle design is fine for most applications. Sometimes they will flip when loading and unloading if you don't have something like a jack or legs under the rear of the trailer when driving on a heavy load. Most likely that is how your frame bent due to all the weight of a heavy vehicle being supported by the single point on the frame where the equalizer was hitting.
Is the upper side of the frame bent also or is it just the bottom? If the upper is not bent you might bend it using the chain and bottle jack method mentioned before. If top and bottom are bent then use the bottle jack method but anchor it closer to the jack rather than across the whole trailer. If only the bottom is bent then you should use s spreader inside the frame rail to straighten it out. But you may have to rig up a way to do it because you likely don't want the right tool for that job. If the metal is thin enough you might reverse the ends on a clamp to spread it. You could also try a piece of all thread between two thick metal plates that have been drilled and spread then with two nut and a wrench. If you need hydraulic force you can remove the deck board and put the lip of a bottle jack on the lower side and strap it in place before using the chain and jack method. Also when you anchor you chain make sure that you spread the load out or you will just dent the frame where the chain is hooked.
Once the frame is straight I would box it where the suspension mounts. You really don't want to anchor you straps there anyway but if you need one weld an anchor point on the side of the frame there. Trailers usually fail at the tongue or suspension so beef those parts up.

xjtony Flip shackle/springs back right and it should sit level and be all good. They will invert and get all wonky if you jack the trailer up empty and not flip them back before setting the trailer back down. Looks like what happened to me.

dave_dj1 Of the three car trailers I have owned they were all made from angle iron and flimsy as fuck! Depending on where or how they were parked they all looked tweeked. Put a chain from front to back over the top, put a block and a jack over the bent spot and jack, hopefully lifting the back up, then box the inside for a couple of feet at the bend.
good luck.

I owned my trailer for about 22 years before I bent it, and that was only because I was pushing it's capacity and had to do some severe evasive maneuvers at highway speed. Up until that point, I had hauled cars, trucks, tractors, small forklifts, firewood, and all manner of other shit that was within the capability of the trailer and never had a problem with bending it.
Travis..

Edit; seeing that shackle inverted, you can see where the frame was riding on the shackle/equalizer and it bent right behind it. Straighten/stiffen it, get the shackles sorted out, and it will be fine.


Thanks for the advice, I plan to just haul my Jeep on it 1 or 2 times a month. It definitely wonít be overworked like it was before. Hopefully Iíll have a semi decent trailer by the time this is all done.

lots of force there, so don't be fucking stupid. It's gonna scare you when she flips back round.


Thanks for the heads up!

Bo185 Look at the first picture the driveway is pretty sloped and trailer is way nose high, equalizer is were it will be like that, shackle should settle back when front axles moves level again. Place trailer on level ground it should level out before you waste time.

Just take the wheels off that side and monkey with it till it flips back to the correct way.

That typed... if you want to keep it as straight as possible, then I've seen angle-framed trailers reinforced with scaffolding above the deck height, and they seem to hold up well. In other words, add a 'rail' about a foot above the deck height, along both sides and the front edge. Then, weld risers and angled braces to the 'rail' in such a manner as to create a scaffolding effect. This will 'solve' your issues from re-occurring.


Thanks, thatís definitely something to consider if I do end up keeping this long term.

DozerDan How cheap? Does it follow straight?

You could always just brace it up as it and deal with it.

ironmangq Heat it and beat it would be the easiest. Those are almost always made from mild steel channels, no worries about taking the temper out of them.

The tubing was the same height as the lumber, so it was flush to the top rail with the wood. That trailer was straight and firm after that. I traded it off to a buddy of mine a couple of years ago and it's still going strong.

Awesome! Thatís good to hear, this will probably be the route I take. Iíll just have to get a buddy to do some welding for me.

If you're planning on keeping a trailer for a while I'd keep looking for a deal on one with a channel frame and sell this one off when you find it.


I definitely want to fix this one up since Iím kinda stuck with it now, but I donít think itíll be a long term trailer.
