I NEED to get the 4wd to work first! Last winter, my '00 sport would not engage into hi or low. Only had a problem once the year before that. I left it in hi and went into a store for 5 min. Came out and it was back into 2wd with the t-case shifter still in hi(light on dash was not on). After playing around with it, it went back into 4wd. No problems after that. Then last year, it never worked at all. I was close to selling it but decided to keep it. Now, it will be turned into a mild toy(also 19 in. of snow on the ground!) and I have been told to look at the linkage on the t-case. I have done this with my dad who is decent with his mechanic skills. Things looked ok and I have no issues with the handle going through the gears. Did we miss something, or do you guys think it's internal?
