My truck will not shift into 4 low, the light flashes but will not engage. 4 hi and AWD work fine, anyone else had this problem?

| I've been reading at various sites about problems with GMC 4x4 performance in snow. Many people seem to be saying that no matter what they do they can't get decent traction. Most of this seems to be related to not having locking differentials at both ends of the truck. I know that none is offered for the front but a friend of mine said that the traction problems are considerably reduced when you have the locking rear AND the StabiliTrak option (with Traction Control). Is anyone able to confirm that their 4x4 truck with these options does well in snow and also those without BOTH of these options do NOT do well? I am considering a GMC for my retirement vehicle and it will see lots of snow in western Montana. I don't want to end up with a "2x3" as some have dubbed these poor perfomers because one front wheel gets no traction and brings the rig to a halt. Any other suggestions are welcome for a good snow truck. I notice that StabiliTrak is not available on the 2500 or 3500 for some reason(?). Thanks. | |

I have a 2000 chevrolet 1500 with the 5.3. It has the autotrac with pushbutton on the dash. Now for my problem, When I press the 4hi, Auto 4, or 4 low , the lights just blink and it will not go into 4 wheel drive. When I push 2hi the light comes right on. It will shift the transfer case into lo when I push the 4 lo button, but the front wheels do not engage and the light just blinks. I have replaced the switch and checked the ATC fuse and the 4x4 fuse. Any suggestions?

I recently purchased a used 2005 Z-71. It has after market wheels and tires. The tires are 285/70-17. This truck is about 2" higher off the ground than most other trucks of similar vintage. I compared the original tires (265/70-17) diameter to the 285's and found that there is only about 1" difference. This would result in the vehicle being only 1/2" higher. Any thoughts as to why the difference in height? Thanks Egor |
