i bought my car with 15K miles. one of the first things i did was change the lift bolt. its an 02 and the new design of the bolt was inside. believe it or not, there was a very light sign of wearing out a little. well the bolt is gold color, but there was a line going around the bolt on the near top white. so paint chipped off there, but other than that it was OK. i dont know how often the previous owner went on lift and i hope he/she never did. but i am willing to change my lift bolts every 15K miles.
