How Did I Manage to Destroy My Anti-Sway Bar?

Just made our “maiden” voyage in out new 33.5 foot Salem 241 RKSS-having just traded in our 26 foot 2017 QBXL Cruise Lite. After a 2.5 hour drive down very straight highways and freeways, I arrive to find my anti-sway bar handging off the hitch attach point. The frame attach point was bent almost 45 degrees out, with the 2 aft heavy self tapping screws pulled. The only turn I made was a left hand at our storage lot, which was somewhat tight but not close to jackknifing.

I’ll get this fixed, but can someone help me understand how this might have happened so I can avoid a repeat? Did I have the bar too tight? That is the only thing I consciously changed due to increases weight and the fact we were on I-75 with a 75 MPH limit and lots of trucks. Same hitch as before.

Thanks.

Too tight or backed up with it.

Was the ball installed in the right position? If too far forward he moving bar would have bottomed out and the the ball had to move or break.

When getting it fixed make sure to check to see if it's in the right position. Check manual for proper dimensions.

Also, the self tapping screws may not be the best fasteners for the job.

But wouldn't a better fastener do more damage to the frame? Sometimes it's better to have a sacrificial part.

This is true... but whomever installed this bracket could have overtorqued the self tappers, thereby weakening them. The OP may actually have done nothing at all wrong, and just had two weak self tappers. Next weakest link in the chain is the bracket where it bent.

It definitely looks like that left turn is what did it for you. However, I have doubts it's just from hand tightening it. Even without the missing set of self tappers, it'd take a lot of force to bend that steel. The friction pad on the anti-sway should have failed first between those two. The way the plate is rotated, the ball is farther back from the tongue, so it might be possible the anti-sway reached it's maximum distance and then when it couldn't extend anymore, something had to give. I'd be looking at your measurements compared to the the specs and making sure it was installed in the right location. You may need to flip that plate over and install the ball closer to the tongue (provided that plate/ball can be salvaged.)

You cant really over extend them. i thought the same with mine, as i was worried. If you loosen that bar all the way, it comes out, there is nothing holding it in. i would suspect stripped out threads from the install, wrong location, or backing up. any welding shop can weld that on for you.

I've pulled mine out and hit what felt like a 'stop'. Maybe if it was looser, it'd fall out, but at the 'just able to slide it by hand' tightness I had it at, it stopped. Course I didn't try to force it either, I was just pulling it out to hook it up.

I don't see how backing up could have done this, unless it was backed to the left. Normally, the damage from backing up is caused on the side that goes short, when it can't collapse anymore, and then the ball would be forced rearward, not pulled forward.
