Third Major Blue Ox Casualty

Yesterday on our first trip of 2014, our Blue Ox Aventa LX Towbar separated in heavy traffic on I-85 near Charlotte, NC. One leg of the towbar came completely loose with the stub end dragging on the concrete road surface.

We were 41 miles from our destination (Freightliner Service center in Gaffney, SC) bumper to bumper in 4 lanes of heavy traffic when a truck driver passing my on the right motioned that I had a problem. Glancing at my rear monitor, I could see that my Jeep Liberty was no longer in its normal center position but about 2’ to the right and being pulled by only one leg of the Blue Ox. I edged over two lanes of traffic and stopped on a broad shoulder. My Jeep was pressed up to the back of the MH.

Removed the destroyed tow bar, wrote a note, locked the car and drove to Freightliner. Retrieved the Jeep a few hours later after a $75 taxi ride.

The tow bar leg attached to the car about 16” long has threads on the end but dragging on the road surface heavily abraided the end. The rod either came un-screwed or what ever it was connected to broke. No damage to the MH.

This is our 11th season with our 2004 MH, about the 7th or 8th with this tow bar. We’ve towed this Jeep more than 80,000 miles with this system. I bought the Towbar on Ebay as a factory refurbished system. It was shipped to me directly from Blue Ox. The towbar is rated for 10,000 lbs, my MH receiver for 6000 lbs and my Jeep Liberty weighs 4000+. I use a Brake buddy auxiliary braking system.

In September 2011, the Blue Ox base plate totally pulled off the jeep while making a slow left hand turn at an intersection in Amarillo, TX. None of the four bolts were found but I suspect the correct locktite may not have been used, even though I was assured it was professionally installed IAW the Blue OX instructions. I sent the tow bar back to Blue Ox for refurbishment but it was returned stating it didn’t require refurbishment.

In September 2012, at a SMART National Muster, I had a Blue Ox representation check my base plate and service my towbar.

In March 2013 arriving at a military RV park in Alamagordo, NM, the entire base plate was ripped off from the Jeep while making a slow left hand turn inside the campground. One bolt was sheared off, two remained tightly bound but ripped a 4” square from the Jeep’s box frame. This time it was repaired with heavy steel backing bars, twice the number of much larger bolts and tack welded nuts.

I've reported both of these incidents to Blue Ox with photos but never received any response.

I’m an engineer and a pretty conservative driver, with one traffic ticket 20 years ago in 60 years of driving. Until I attended Camp Freightliner last year and learned 1700 rpm (61 mph) was the sweet spot for my engine, most of my 115k MH miles have been at 57-58 mph.
We’re headed for Arizona with multiple reservations and invites from friends so today I’m headed to the nearest Camping World (Spartanburg, SC) to select a new towbar and have my base plate checked.

Tell me what I’m doing wrong? What should I be doing differently? And remind me why after thousands of dollars in repair bills, I will probably choose another Blue Ox to attach to my beefed up base plate.

    My point is to everyone, if the safety chain is not wrapped around or attached directly to the frame, it is not a safety chain, it is a joke. Anyone who spends much time on any RV forum can remember posts of baseplates coming loose or breaking. This seems to happen every so often.

    On my Blue Ox Aventa and baseplate, the detachable safety cables do attach to loops on the front of the baseplate, but (when correctly installed) another set of cables secure the baseplate to the toad's frame. I've heard tales on this forum of baseplate installations that skipped that step.

    Re: the baseplate coming loose... on my first towed the dealer (professional installers) did not use locktite.. I spoke with the installer on my 2nd towed (Hitch Center) and they say they did but thank you for reminding me.

    No loss in the first case (Well small loss, perhaps 2 bucks) as we found the loose nuts and one missing bolt before disaster happened and fixed it.



    But FOLKS.. CHECK THOSE BOLTS!!!!!!!!!!

    It is hard to tell what actually happened without looking at pictures of the failure. But maybe if you receive enough guesses you can piece things together of why this is happening. I would start by looking at the failure site it self. Does the metal have very small grain structure indicating work hardening of the metal. This would indicate to me maybe some excess clearance in the load path of the bar to the frame of the car so each time you start or brake excessive handling loads are applied. Like if you were water skiing and there was slack in the line and the boat driver goes full throttle it would put way more stress on your shoulders than if there was no slack in the line. Handling loads from a tow motor on an aircraft for example can be 10 times as much as it sees in normal fight operations. This repeated applied load can work harden the metal and eventually lead to failure. the 4 in piece that was pulled from the frame leads me to believe that this is the failure mechanism. My friend had 2 failures like this with his Blue Ox. Hope this helps you find the cause.

  • If you really want to be biased you can blame Blue Ox. Or you can really search the web and see there are failure on others as well. Personally I would never buy a factory refurbished anything much less a tow bar. Another thing comes to mind is if you don't personally inspect your equipment ( at least visually and try to tighten anything loose ) every year your trusting someone else to do it right, which doesn't always happen.

    There are others issues as some here have indicated. Blaming Blue Ox for your failures seems like the easiest excuse. I'd be considering a new tow bar at that point anyway. But I tend to lean on the safe side.
  • If my count is correct you have had three failures on an under loaded system, and you are going to buy another one? One of the definitions of insanity is that you keep doing the same thing and expecting a different outcome?
    I spent my working career in QC, nondestructive testing, working on everything from the space shuttle and nuclear subs to carnival rides. This sort of catastrophic failure that could have lead to a fatality is absolutely not acceptable. Do a search on Blue Ox failures, you are not the only one!
  • Hi,
    Few things come to mind, ever back up even just a little with toad hooked up?
    How level is tow bar?
    Any extreme gutters or dips you drive thru where tow bar hits roadway?

    Possible that first time base plate bolts came loose it stressed or fatigued metal on jeep frame. Just a few thoughts

  • I am sorry to hear of your troubles and damage. I have been using Blue Ox for over 20 years, and am very surprised to hear of their reaction, or should I say no reaction to your problems. I have only had one small issue with a tow bar in all these years and it was attended to very promptly. In fact I went to Blue Ox to have the baseplate fabricated and installed on our new 2014 Dodge Ram 1500 truck. They were professional and did a great job. I hope they work to make up for the failure and do the right thing for you. It is unbelievable to me that a baseplate can be ripped off a vehicle at all and to have it happen twice is phenomenal! Makes me wonder if it was installed properly with correctly rated bolts?
