Question Blue ox questions

I am towing an 09 wrangler and have two questions about the Aventa tow bar.
1. I will have both latches secured when I start to tow, and when I stop , sometimes one will be unlatched. I can make a turn and it will latch. Is this normal?

2 When I prepare to unhook there is so much pressure on the tow bar that I can't release the latches or pins on the base plate. Is this normal?

1. No, that's not normal. If it's latched when you start, it should stay latched.

2. Can be, especially if you were in the middle of a turn when stopped. I've never had a problem when I was level and straight when stopped. It's almost always jammed when the toad isn't straight, like after a turn into a pull-through. If I'm sure I'm going to be unhooking anyway, then I'll usually do so while DW is registering in the camp office. Usually the registration parking spots are fairly level and straight. But not always.

I would get Blue Ox to inspect your towbar if #1 is happening.

The trick to getting the latch to release in a bind is to turn the steering wheels of the toad and this shifts the tow bar enough to relieve the tension.

Our tow bar binds all the time if we're not level and straight. Also, stopping gently when you're ready to unhook helps reduce pressure on the pins.

Turning the toad steering wheel as RV Wizard says usually frees a binding condition. Also, keeping the pins (and holes in the tow bar ends) clean and occasionally applying a dry lube helps make the pins easier to remove if there is a slight bind.

No and possibly. Definitely fix the latch. You wouldn't want to stop and find both latches had come unhooked. If it is a non binding all terrain tow bar it shouldn't bind. Keep it cleaned and well lubed and you shouldn't have that problem either.

I agree 1 is not normal Contact Blue Ox their customer service is very good in my experience.

As for 2.. Yes, that does happen.. sometimes I have had to start the towed and engage the axle and put it in either Driver or Reverse (At full idle) to get the latches to release. I DO NO RECOMMEND THIS. Note if you do this put it back in PARK before you pull the tow pins.

Also turning the wheels from side to side (Steering) can sometimes free 'em up
I do recommend this method.
Home is where I park it!

Thanks everyone. I am calling Blue OX today. The first time I called they said this is normal. I didn't think so. Thanks for your experienced views. Have a happy 4TH.

Review paragraph 6 of the Blue Ox operator manual under towbar maintenance. It explains that the latches will feel loose when not under compression. Under compression one or both will feel tight. We just returned from an extended trip and found that at times one of the handles would feel loose, but when hooking up heard and saw both arms click or lock. Yet, one handle would still be loose. Monitoring the backup camera I could verify both arms would be locked by making turns and manuvers and watching for retraction of one of the arms.

I think what you are experiencing is talked about in the manual from Blue Ox it says

In normal straight line towing conditions, both legs
will be in tension. Due to the design of the latch,
both handles will feel loose. During turning, braking
or parking one or both of the legs may be in
compression. This will make the handles feel stiff or
tight. Due to parking on slopes or the angle between
the coach and the car, the two locking mechanisms
could be in compression or tension or any
combination of the two. Having one lock in tension
and one in compression may give the operator the
feeling that one leg is locked and one is not, when in
fact whenever the legs are fully extended and the
springs are holding the latch handles up, the legs are
locked and ready to tow whether in tension or

As for #2 keep the pins greased and at times I've used a pin punch to drive one out.
