I'm just curious

I don't really care because I have manual locking hubs on my sport but my 4x4 and low range light on my dash are not coming on when I put it in to ether just wondering if it could be the bulbs or something else.

the transfer case is probably not shifting into 4wd
Hubs do not help the t case shift from 2wd to 4wd

check your fuses

the shift motor on the t case wears out in time and could easily be the cause of the buttons not working/t case not shifting

The hubs merely lock the wheel to the axleshaft, it won't do you much good to lock up the wheels to the axleshafts if the t case is not shifting power to the front end/ axleshafts

My transfer case is working just fine I've went off roading in her and she done amazing when in 4x4 and I've also checked on my own time just by pressing the button and I hear the transfer case go into both

okay so the bulbs are out in your switches if you are indeed getting the 4hi and 4 low shifts
