Ouch! My first guess would be bad front shock... assuming towbar and baseplate connections are all OK that is.

Blue Ox says adjust camber

Add me to the list with the problem. I have a Blue Ox tow bar and first thought the problem was the arms weren't locked. The problem happens for me when I go over worse than normal bumps.


Blue Ox support says that they have gotten several calls on this from Cherokee owners. They suggested two fixes. 1.) adjust the camber on the Cherokee - they said customers have told them there is an alternate setting that prevents the wobble but no one has told them what the setting is 2.) put bungee cords on the steering wheel to reduce swings.


Has anyone tried changing the camber? If so, to what setting?

You make sound like it occurs often, I pulled mine for 3k miles this summer over some rough roads and did not experience this, I have a blue ox base plate and a 8k pound Excalibar Demco tow bar, I wonder if this could be caused by lighter weight tow bars?

Looking for common denominator - tire pressure?

I'm getting the problem using a new Blue Ox Aventa which has a 10,000 lb rating so its not unique to low weight rated tow bars.


I have also had the problem 4 times over less than 2,000 miles of towing.


The Jeep's front tires are a little over inflated (35 lbs cold) and I know the last 2 times I had the problem it was after towing for at least an hour on a hot day (over 80 degrees F). Is it possible that its related to tire pressure?

Don't think it has anything to do with the tow bars. The death wobble sets up at low speed and slams the front wheels from side to side. It only happened to me once while making a turn. Probably going around 5 mph and ran the front passenger tire over a curb. The tires (and steering wheel) violently oscillate from side to side. The only way to stop it is to come to a complete stop. Then all returns to normal.

Wonder what the best way is to report something like this into FCA engineering so they can look at it?

Hi Bruce@twoflyrodders, I would like to be added to the list but don't know how to PM you. Please advise.

We had our incident in the Redwoods of Northern California this weekend, a very bad place to pull over for this unnecessary problem. We were going through a construction zone that pushed all traffic over to the shoulder over a slight drop in the pavement when the rocking started. A CHP officer followed us off the road because he saw the car jumping about wildly. The rocking was so violent that the 10 cases of wine we were carrying in the Jeep flew all over the cargo area, we lightened the load considerably after finally reaching our destination, what a day!

We have filed reports with the Dept. of Transportation and will soon file with Chrysler. Thank you so much for organizing this effort.

Mary

Add us to the list. Just completed an 8800 mile trip from Fl to Glacier National Park Yellowstone Grand Tetons 5 National Parks thru Utah etc. Had the wobble happen once in Idaho. was traveling about 15-20 miles per hour on a multi lane road and crossed multiple railroad tracks at an angled grade crossing. Shook the motorhome an unbelievable amount. Was able to pull into a left turn lane and stop. Got out checked, everything appeared fine. Did not happen again, but I was very concerned for the next couple of weeks crossing RR tracks at highway speed.
