Bought a Cherokee Limited today. Took everyone's advice and tried to get something that already had some mods. I didnt want that much lift, but oh well. Here's what it's got:

5" Rubicon Express lift kit--full leaf packs, SYE, Rear CV driveshaft, sliders, skid plates, front rear reciever hitches, pre-wire for winch, aux lights, brand new Dick Cepek 31" tires and Cepek 15" rims, Chrysler 8.25 rear, stock exhaust, throttle body spacer, stock engine, all at 90K. Drove smooth. Mild vibration around 45mph, but otherwise good.
It's my first Jeep. Are there any cool "cheap trick mods" for these? What kinds of maintenance issues should I pay attention to? Want to learn as much as I can like I did with my 4Runner so any advice would be appreciated.
Headed to Lander WY this weekend to try it out.
