If you have ever had a trailer break loose off your trailer hitch before you will relate to my story. Today was my first and hopefully only experience with this. I have been pulling trailers for many years and have always hooked up the trailer and checked all of the safety chains and alike. Yesterday evening I rented a U-haul to help one of my employees’ move some house hold items and the U-haul representative hooked up the trailer to my Suburban. I looked at the chains and everything looked good. I traveled 90 miles to pick up her belongings and returned last night without any problems. I parked the trailer still hooked up to the Suburban last night and this morning I was returning it back to Venice. I did not even think of rechecking the trailer when I departed, which was the first time and the last I will ever do that again. It was raining and is still raining from a tropical depression passing over.

I was just a mile from my destination to drop off the trailer and in heavy traffic driving in the left lane traveling at 45 mph on a curve when I hit a bump in the road and the trailer let loose. The trailer was swinging back and forth and rocking my Suburban bad. I could only think that this is going to be a bad accident. I knew it was just a matter of seconds before I heard the crashing sounds and the uneasy feeling of loosing control of my vehicle. I held on tight and remarkably nobody got hurt. Cars where scrambling all over the highway while they were breaking to avoid my unfortunate situation.

The trailer rolled forward into the back of my Suburban and then bounced back before the trailer brakes took hold. I had my vehicle in the median and I finally came to a stop. My heart was pounding and I was getting the shakes when I stepped out to see the damage. I looked at the traffic to see if anyone was involved. After that I looked to see what happened and why the trailer broke loose. This is what happened. The ball lock was unscrewed. I knew right then that I made a big mistake by not checking the connection before I left.

I have learned a few things about trailer brakes today. One, the brake chain or cable needs to be shorter than the safety chains for it to work if the trailer breaks loose. Secondly, if the trailer is loose and is not heading in the same direction as the tow vehicle when the brakes are activated the ability to control the tow vehicle is just about gone.

I will always make my own connection and will never trust my safety in the hands of someone else without double-checking.

Ditto. Also hope you give the U-Haul guy a good a*s kicking.

Wow, Glad you made it through.

Can you give an estimation of what would have happened if you were pulling with a Corolla or a little mini SUV like a Forester to help with the "Can I tow a 17' with my Corolla" questions that always come up?

When you say "ball lock" do you mean the mechanism that is connected to the hitch lever that is actuated upward to secure the ball inside the hitch housing when the hitch lever is flipped down?

Peter,

The U-Haul I used last week didn't have a hitch lever. The connection is made by turning, what amounts to a big nut on a treaded shaft. As you turn the nut it draws up the lower jaw of the ball receiver. I think U-Haul uses this type of receiver to accommodate a range ball sizes.(1-7/8" - 2-3/6"?)

Inhernet,

Any damage to your vehicle? When we picked up our rental they said they can't help with the connections. I took this to mean they didn't want the liability. Having seen a number of very serious accidents with vehicles towing trailers, it seems you made out just fine. What size ball did you have? I noticed when tightening the hitch mechanism it still seemed a little loose so I had my friend lift up the tongue to get the hitch mechanism tighter. (A lot of help it does you now) The first trailer they assigned us had a bent tongue and we refused to use this trailer. They found us a different trailer at another location.

Thats supposed to read "what amounts to a big nut on a threaded shaft"

This should not be construed as a description of any person or moderator on CW!

On our [I]pickup truck[/I} trailer we have the but nut on the tung like you guys are talking about.

We where towing once and it was making a funny noise. At the a red light I got out to check it, it was loose, and ready to fall on the street, we got lucky. Ever since that day we always make it real tight with a big ass wrench.

I'm glad that it didn't turn out worse than it did. I hope the suburban isn't too badly damaged.
Trailering always has the potential for some sort of problem, but that's a bad one.
I'd rather have tail light issues!

The ball-locking device was a screw with a bolt on the end. The screw loosened and this allowed the ball socket to release from the hitch on a bump. I do believe I have read somewhere that you should check the trailer connections and lug nuts every one hundred miles or so. I wish I could find that information. The damage to my Suburban was very minimal; the only damage was to the metal light connector plug. It was broken off and the metal bracket was bent in. This is where the trailer tongue hit on the forward motion. It is amazing how much sway the trailer has when it is going one way and the tow vehicle is traveling another. It puts some real pressure on the tow vehicle and acts like the tail wagging the dog. The safety chains allow the trailer to swing quite a bit once it got rocking. I do know that if you want the trailer brakes to work you need to have the brake cable or chain shorter than the safety chains, otherwise the safety chains will keep the brake cable from engaging the brakes until the safety chains break. I am just thankful that I was not traveling 70 plus on the highway. Sure is a wakeup call.

To do away with a bolt possibly coming loose, I bought a trailer tongue lock. It is fully locked before I can hitch up and then locked after I am done hitching.

GNR - You have been watching too many Scary Police Chase shows. I know you are being facetious with the Corolla jibe but what would be wrong with pulling a 17' with a Forester? The tow capacity is 2000 lbs. And talk about leading the witness with "in your estimation".

What happens if in his estimation that he would have been fine? Will that sway your opinion or change your mind about towing with a smaller vehicle?

My question was a sincere question.

"The trailer was swinging back and forth and rocking my Suburban bad. I could only think that this is going to be a bad accident. I knew it was just a matter of seconds before I heard the crashing sounds and the uneasy feeling of loosing control of my vehicle."

and this was at 45 mph.

This is a perfect case in which to try and draw some comparisons. If the 5000lb Suburban was "rocking bad" isn't it reasonable to assume that a vehicle of less then half that weight and wheelbase would have been pushed around much worse?

I am not leading anyone and I am not trying to be facetious. I used the Corolla because that was an actual question a few weeks ago on this forum.

The fact of the matter is that your reference to me in your post is pure trolling, plain and simple. It had nothing to do with the original post and its purpose was purely to take a jab at me.

Please tell me exactly what your problem with the "in your estimation" comment. The man just went for a wild ride in his Suburban. He knew exactly how it reacted. Now if it was me I'm pretty sure I could come up with an "estimation" of how things may have been different with a significantly lighter, shorter vehicle.

Seems to me you may have reacted more to my screen name then my post. Ayup you are a class act yessiree.

No he wouldn't have changed my mind because my opinion is based on twenty-five years of towing experience.

FYI I have towed my Guardian 17 three times with my wives FORESTER. Yup, it'll pull it. It is definitely back there though. Works to hard on the hills and it adds considerably more to the stopping distance then the same boat does to my F250. I would never buy a used Forester from someone who towed with it. Course I don’t take for granted everything the salesman tells me when he is trying to sell me a vehicle either.

I guarantee you that if your 17 breaks loose from your Forester on a corner at 45 miles an hour you will be very lucky to keep that rig on the road and upright.

Course that only happens to other people right?

Let me ask you a question. If you have an outboard with a max rpm of 5500 do you run it right there all the time with no fear of overworking it or do you tend to cruise down at 4200 or 4500 rpms? Kinda the same thing as towing at the vehicles max rating. Sure it will do it but there is a price to pay.

In the future you might wish to take a deep breath and re- read the post with an objective eye before you set your lines for a little trolling.

i lost my first boat that way a few years back,luckily and i still don't know how this happened,it did'nt take me or anybody else with it.that is a very unpleasant feeling when you know it is'nt hooked up anymore and your going 50 mph.

GNR,

I am too busy to go trolling, unless it is for fish on a weekend. My reaction to your comment strictly relates to the prevailing wisdom that you need to tow with a Ford/Chevy/Dodge pickup/suv or you are asking for trouble. I will certainly agree that it is EASIER to tow with such a vehicle, but it isn't always warranted.

For a 17' whaler, you are in the 1400-2000 lb range depending on model. This weight isn't going to place a great deal of stress on a modern car/truck. The engines are far superior in horsepower, cooling and reliability than 10 years ago. The braking department has made HUGE leaps from even 5 years ago. Vented 4 wheel discs offer proven, repeatable braking performance. Tires and suspensions are also night and day better.

The post from a few weeks ago that I remember seeing, asked about buying a Honda CRV to tow a 17'. I never saw any mention of a Corolla. The responses were that the vehicle only had a rating of 1000 lbs, obviously not enough.

By no means was I taking a jab at you and I have no clue where you were going with the reference to your screen name.
When you ask for an estimation of what would have happened if he were pulling with a Forester, shouldn't you be able to answer it since you own one and have towed with one? Does this not sound like a troll?

Any vehicle that loses a trailer will be pushed around, simple physics at work. A 5000 Suburban will take more to push around versus a lighter vehicle, simple physics again. But how much vehicle weight is enough? Should the tow vehicle be able to handle twice the weight? 1.5 times? If a driver of a Suburban was very concerned, should he upgrade to a commercial grade dualie so he has even more weight and towing capacity?

In regards to the stopping ability or a Forester vs a F250, a trailer will add more to the stopping distances, but you also need to figure in that the smaller vehicle would stop much sooner than the F250 to begin with.

Example - A Subaru WRX STI has 300 HP, 300 lb/ft of torque, huge vented disc brakes and a towing capacity of 2000 lbs. It can stop from 70mph in approx. 160 ft versus over 220 ft for an F250 (no trailers on either at this point). If, for arguments sake, the trailer now degrades the STI's braking by 20% (never happen, but lets play along) the total is still only 192', a full 28 feet less than the unladen F250. Wouldn't the STI be a better hauler for a 17' whaler than the F250? Better power to weight, better handling, better braking, and far superior fuel economy.

I was very sorry to hear of the trailer troubles that InHerNet experienced. No one wants to see any trouble like this happen to anyone. I appreciate the fact that he shared the experience with us, as it is a good lesson for everyone.
