having different tire sizes will effect stabil control. abs system and make transcase red nutral light come on. also low tires pressure. always have same size tires and proper air all around on awds. mine went red once and felt like it was only running 2wd. low tires pressure up front. wonder if i can keep in red if it does stay in 2wd it should have more power output.felt like it did when red light came on. i dissconnected front driveline to see if i could drive becausefront pitment arm makeing front tires pegion toe when getting on it. and truck did not move back or forward. make grind noise back to park. puting driveline back. but still want to try and run 2wd. maybe disconnecting something where to make light come on again and run 2wd and keep that way. has more get up and go.

I have 2003 burb with same set up no 4 hi just stability neut line then double axles and 4 low ..
There is a yellow light sometimes its on beside double axles then sometimes its off ...i have a service stability message sometimes ...and i can not figure out if 4 hi is working or not or if its on all the time manuel says nothing ...
So is light supposed to be on alway only when it goes in to 4 high ...is it all wheel drive or switches if roads are slippery
???

Hey fellas, go the the GM Heritage website and click on Vehicle Information Kits, then select your truck and then the year. You will then get a pdf of a detailed description of your truck. Get your RPO codes, especially the "N" codes as that will tell you which transfer case and drive system you have. Then have it and figure it out.
