don't spend the money on fancy rotors, pay more for pads rather (they make a lot more difference than the rotors). Bendix TitanuMetallic II for me worked better than anything i tried before. I got refurbed Raybestos calipers and some generic rotors.

Sharp, thanks for the advice on the brakes. I'll be ordering them this weekend.

18mpg this last tank. Pretty happy with that.

Got the Misch's seat brackets in, pass seat belt in, ordered the AMSoil. The rear diff leaks but i can't tell if its the old plug thats leaking, or not enough RTV thats making it leak. There is still plenty of fluid in there and it never needs any but the fact that its leaking period is freaking me out.

The Big Boy bracket is in.... I have plenty of room now and driving is now a much more comfortable affair. The only negative is trying to see stoplights when I'm "first in line", because my line of sight is on the top of the window. The bracket made it harder to see stoplights than before. However I am dialing in a route that only has 3 stoplights instead of 20. I'm going to write a review in the nuts and bolts section.

Continual money problems have kept me from affording brakes.  The ominous noises the brakes were making quit though, so I'm not as worried about it. The exhaust fell off, but continues to hang on, banging around in the undercairrage. The CEL keeps flashing on and off, its never on when I am near an auto parts store, as if its mocking me. The rusty body mount is now hanging in midair, the rust that made it look like it was attached to the tub got pulverized off of it. There are several totally asinine squeaks in the cab that have me trying to hold panels in the cab while driving to see where they are. The pinions seals now both leak significantly. One U-joint is on its way out, its weeping grease.


I had a 1988 CRX for two weeks, I had put a headgasket in it 3months ago... Well, it re-blew up with me driving the car, not the person I did the job for. Which is a relief and a slap in the face at the same time. 30 mpg was VERY nice while I had it....

Changed the trans fluid to Amsoil MTG. Huge improvement over what was in there. Honestly... The fluid that was in there was in good shape and I wouldn't have changed it. Shifts easier and better. Whole jeep seems to roll easier, doesn't lose as much momentum on hills. Its an incremental improvement. It cost around $90 for the fluid which hurt but so far, its worth it.

The Jeep still chugs on... Leaves a little trail of blood, but chugs on... Hopefully this weeks paycheck will get it fixed...

Babied the hell out of it for a tank to see if I could pull 20 out of it. Got 14.9. Got mad.

Said **** it and bought a Subaru.

If you have 31's and were babying it, I bet you were lugging the engine all the time which isn't good.  When under power, the key is to keep the engine running in it's optimal powerband without letting it drop too low or too high.  If you have gravity on your side then you can keep the RPM's down without worrying about lugging the engine.

Im with jeffy, with 31's I was geting 17mpg regularly with my yj and I was driving fairly normaly (not flooring it all the time but getting up to speed fairly quickly and keeping 65-70 on the highway with about 30 % city 70% highway. That is with a tbi 2.5l which your mpfi should beable to beat in mpg if everything is running correctly.

Not sure what it was. I didn't lug it, (been on here long enough to know that) just took it easy 60mph instead of 70 on the highway, 55 flat on the country 2 lanes instead of 60-62 with traffic. I thought, hey, this tame driving is going to stretch this tank out. Wrong.

I was using the jeep for something its not designed for, so its for the better.

I still have the Jeep, for now it will just be a wood hauler. There will be no more whining about MPG's. :)
