If you own a Jeep Cherokee between 2014-2019 (like we do) you may know about the death wobble. We installed a flat tow kit (recommended) by Jeep. This wiring kit keeps the battery running while towing the Jeep so that the EPS is active. Problem is (as acknowledged by Jeep) that it drains the battery and thus when the battery gets too low, it shuts of the EPS and guess what, The Wobble. I recently added a Solar Battery Maintainer and it seems to work. Traveling near Cleveland today, we went into a short turn with several rumble strips which provoked the wobble. We stopped and then started again and no wobble the rest of the trip.

I am having a  battery  line installed from the rig battery, through the 7-pin connection and directly to the Jeep battery. The hope is that it will constantly charge the Jeep battery so it doesn't shut off. Seems like my only hope. I am still perplexed at the wobble when going over the rumble strips and the wobble started. 

When the wobble happens, it triggers the "check engine light."

IF THIS SOUNDS FAMILIAR, WOULD LOVE TO TALK WITH SOMEONE..IF YOU'VE EXPERIENCED

THE WOBBLE. IT REALLY TAKES THE FUN OUT OF OUR TRIP.

SHOULD I GET A DIFFERENT CAR?

Death wobble is a common problem in Jeeps and many other solid axle vehicles. There's no silver bullet cure, but common causes are worn...bushings, bearings, steering linkage, ball joints, or unit bearings. You may be able to add some caster easier than a leaf sprung vehicle, so after a good inspection of all front end components, get it in the alignment bay and add some caster. Even make sure the caster is consistent side to side, through the whole steering arc.

Sometimes a battery charging line from the motorhome is too long and has too much voltage drop to keep the toad battery charged.  If this happens you can add a voltage booster on the toad and boost the voltage enough to keep the battery charged.

My Smart car has the same problem. An easy fix is to tie a bungee cord to the steering wheel and attach the other end somewhere to keep slight tension on the wheel. This may also work for the Jeep.

Our Smart does the same.  We bungee the wheel with just enough tension to help it return to center.

Yes, this it is always caused by a worn, loose or maladjusted suspension part.  The hard part is that many time it is multiple parts that all contribute to the end result.  On one of my vehicle I could not find it, finally found an old school tech, he lifted it up with wheels about a foot off the ground, put a 6ft 2x4 under the front tire and the leverage from that showed how badly the wheel bearings where worn even though by hand they felt fine and you could not wiggle the tire.

On a Smart car this is caused by the wheelbase to vehicle width dimension..  Slightly longer then wide.
