Sorry for the late reply; I was scrolling through a previous thread and got redirected to this one and saw your comment from Weds.Did you ever get the TSB done? Did it improve the feel and steering? Which dealership did you go to? I go next Tuesday to Pearson Jeep down in Richmond, VA
I live in Northern VA, so I went to the Safford Dealership in Springfield VA. The first time it was done, there was no change. I requested another box, but the dealership claimed a 4-6 week backlog. I went to another dealership (Farrish in Fairfax VA), and they had one ready in a few days. I had it replaced AGAIN, but there was no appreciable change (ie the problem still exists).
Since I had a few hours to scroll through the threads and catch up, it looks like a few things are important to keep in mind:
1. Look at the power steering fluid a few days after the fix. I just checked mine, and it is at min!
2. Make sure that the dealership has the NEW BOLTS! I had to go back and make them change it out. There is a rumor that the bolts are really just the same, but why mess with it?
3. There is a new TSB...08-003-21 (that's right...not 003-20, but 003-21). Ensure the dealership REMOVES THE OLD SOFTWARE and FLASHES THE NEW SOFTWARE for the power steering. Ensure the INVOICE STATES THIS, as the dealership should be compensated by corporate for doing the work. Lastly, make sure they DO AN ALIGNMENT and give you the report. I am going back to my dealership to have my software flashed and my alignment redone because it didn't have it done earlier, and because of this new TSB.
Lastly I would highly encourage you to look at the 2" lift Mopar Lower Control Arms (LCAs) that help with castor (trying to get above 6 degrees). Lot's of encouraging comments about that, and it's pretty inexpensive ($120 for 2 I believe) and you can change it yourself.
Best of luck!
