look at the tires from the ft and rear make sure they line up. general rule (not always) 5 lug is 7k 6 lug is 10k and 8 lug is at least 12k watch for bent axels they suck (i know) check the brakes to make sure they are not froze or not working at all. new lights are easy and i would sugest doing it anyways to make sure you like the way the wiring is ran and spend the extra money on leds and PUT PROTECTION AROUND THEM
