We just got our Patriot back from the mechanic. 3200 dollars later. Oil change, trans fluid change (finally), 3 wheel bearings, two more front control arms/balljoints, new brake pads, and more. It feels brand new as it should. Let see how long that lasts. Hopefully we get more than a year of light driving out of this round of parts.
As for the Appcar settings changes. They all worked great. The jeep feels much more relaxed with its transmission shifts, and overall demeanor. The headlight output is much improved too. Now, to get some new headlight bulbs. I would love LED but I get the intermittent black out using them. I have no idea how to stop that.
