My 4wd for some reason is not working all the sudden. I took it to the shop and had new value gaskets put in and CV Axels. Went to go for a beach ride and got stuck. I was not paying attention to the light at the time. But when I did after I got pulled out I was going down the road and put shift in 4wd and the light came on and went off. Also on the beach I had turned truck of and turned key on and the 4wd light flickered for a second. Thanks for you help!

 

When was the last time it was put into 4WD??

Perhaps when the CV axles were done something got knocked loose or disconnected

 

manual hubs or ADD?
