2007 Nbs 4wd Issue

[twilkie]

Hi Everyone

 

I seem to have an issue with 4-hi. When 4-hi is selected the light switched and stays on solid, but at times the truck is obviously only in 2 wheel drive. It is extremely noticeable pulling away from a stop ( I live in Labrador so the roads are all snow/ice covered) 4-lo seem to be functioning fine, and I believe the auto is as well. Is it possible there is something causing it it to randomly go in and out of 4hi despite the indicator staying in 4hi?

 

I hope I made my issue clear. It is really bugging me driving around town.

 

Thanks!
