Re: Manually shifting transfer case
Your '02 is not vacuum actuated anything....the hubs are "live" meaning they are locked 100% of the time. There's nothing to engage in relation to the hubs.
You've been turning the shaft on the case that normally goes between the shift motor and the inside of the tcase? You should probably replace your shift motor or your 4x4 switch or your 4x4 shift module/computer located on the passenger kick panel area.
