Very well and mileage has been pretty good, considering. I actually got about 20.5 mpg on a 100 mile all highway trip a few weeks back. Never got above 2,500 RPM and set cruise control at 60 (that kept RPMs at 2,200). The next day the temperature was about 10 degrees cooler and another 100 mile trip gave me about 15.5 mpg with a couple more redlights and about 5 miles of city driving in and out of the Air Force base. I haven't been able to get a real accurate reading across a full tank of gas because my odometer is off. Highway driving I'm able to use the GPS and Google maps for mileage and filled up before and after the trip. So, just take these measurements as you wish.
I still fill up once every two weeks, same as before, though. So, where it matters, my pocket, no dramatic change in fuel efficiency.
For the record, and I think it's important, I only run non-ethanol gas and never get above 2,500 rpm highway, 2k city.
I have eliminated all rubbing except for at full stuff and turn. It just hits at the top of the cladding. Considering removing the entire inner wheel well is the only fix for that and I only rarely get that much stuff and while obviously at very low speeds, it's not a concern.
Time will only tell about the hubs and balljoints.
