I wouldn't know for shure about yours but I am shure that some v6 tyotas had the 4.56 gears stock. I think it was the sr5 models equiped with 31s stock. So I'm just wondering what gears your wifes runner has.
Good point, we bought it used so and I never bothered to check because we don't have problems with it.
But I don't want to thread jack here, I just wanted to let this guy know that 5.29's arent the only way to go and maybe not even the best depending on what you want.
