Ok, I've had a this issue before but very random and not very often at all.  Yesterday I was on the highway at 60-70 mph and hit a bridge transition and it went nuts! Again less than a mile or two later. With traffic behind me I had to smash the brakes down to 25mph to get it to stop. Luckily no one rear ended me! 

 I absolutely have to get this sorted out! I replaced the track bar approximately a year to year and a half ago. It was a lower priced one from Rock Auto. I have replaced the left outer tie rod as well. 

 I have read that the track bar is usually to blame but I want to be 100% sure it is fixed for good this time. 

 Any advise or guidance here would be appreciated.

 Also, just to bring this into the conversation, would it be advisable to upgrade to the heavy duty mopar steering kit? Maybe the 3rd gen track bar? I don't know. I just need this to stop once and for all.

Not sure I've heard of these. But I'll do some checking.

 

I am also running the Centramatics - installed one year ago (10,000 miles ago) this month.  I installed them for a particular reason.  I had purchased a set of four commercial winter tires for a good price.  It turned out that they are excellent rock pickers (probably why the good price).  I live on a 1/2 mile long gravel road and those tires load up with rocks.  After two hours of freeway driving, there are still lots of rocks in the tread.  Of course, this affected tire balance dramatically.  The Centramatics have worked well for the fix.  The wheel balancer compensates for rocks leaving the tread, thus making the ride smooth again. 

 

The steel balls are enclosed in a circular tube filled with synthetic oil.  This allows them to work well in cold weather.

 

I think they are available for a dual rear wheel truck.
