scary incident

I have a 09 unlimited 4 door.I was driving on the highway going about 60mph when someone pulled out in front of me. I had to slam on the breaks hard. When I took my foot off the break the steering wheel and the front end started to shake violently it would not stop and the Jeep was difficult to steer. I pulled over came to a complete stop and put the Jeep in park. I waited ten seconds then pulled out and everything was seemed to be back to normal. What the heck happened?

Is your jeep stock? Sounds like after the brake (lockup?) that the Brake Control System - linked to the ABS (not the ESP but a part of it) might have been partially locked or alternating from side to side...just a guess on my part. I tried to lock up my brakes several months ago and they ABS kicked in correctly, but after releasing brakes did not have any problems - I would have the dealer check it out by repeating your panic stop at speed.

Sounds like "death wobble". Brake induced, rather than bump induced, assuming you didn't hit a bump.

there are a lot of different variables , are you stock or lifted/ larger tires / armor?

ABS kicking in always feels a little sketchy or you could have had some temporary brake fade from the panic stop

have it checked out and it might be smart to do some practice panic stops so you know how the ABS will feel/ react
