Automotive → [Help] 2003 GMC envoy

My 2003 envoy makes one noise when being put into awd and the motor makes another noise when switched into 4 wheel it also has a noise in the right front end when going slow and can only use the 2 wheel drive right now because after going about 30 mph it stops the truck in awd or 4 X4

Would you like to try again with something more coherent and a little bit more information so people can help you?
