Wondered if the EPS was a culprit. Brought it up in posts #3 and #23 of this thread. I don't recall any TSBs that include reprogramming the EPS module, so your report is interesting. There is a TSB about "Electric Power Steering (EPS) Module Connector Security" (http://www.wk2jeeps.com/Misc/Cherokee/KL_TSB/KL_19_001_17.pdf) but based on personal experience towing the KL behind a motorhome, if the EPS module loses power (e.g. connector comes loose), it can result in a true death wobble, given the right circumstances, that will not quit until the KL is brought to a complete stop. To deal with the KL being towed situation, FCA designed a flat-tow kit that keeps the EPS powered up when the ignition is turned off. The EPS includes a "shimmy mitigation" program running to counteract the wobble. Suspect that is used in lieu of mechanical forms of shimmy suppression like a hydraulic shock.Possible solution
hi all, I also had some wobbling at the front end for some time and it got pretty much resolved by a reprogramming of the electric power steering (EPS) yesterday.
I've also wondered if the EPS programming had something to do with the half shaft caused wobble issue that was fixed using different half shafts. Maybe there have been some refinements lately in the EPS program code to compensate for looseness in vehicles with more mileage on them.
