2001 Dodge Durango Q&A

2001 Dodge Durango Question: when i put it in 4x4 it knocks/cluncks when i give it gas. what could it be

only when its slick. i dont hear when just in 2x4, i dont hear when i turn -
Answer 1
The noise might be caused by a loose chain inside the transfer case. Or you could have a faulty U-Joint on the front propeller shaft. It is unlikely that the U-Joints on the front drive axles are causing the problem because you don't hear it when turning. -

thank you for your help. i had it checked out, and it was a bad front driveshatf. now i need to know how hard is it to change for someone that is somewhat, but not great at the mechinical side. just never replaced anything like this before. thanks again -

If you are sure it is a bad front driveshaft, Good luck. Just remember both front driveshafts (or half-shafts) enter the tranfer case as well. So I don't know what kind of check was performed but good luck to you. -
Answer 2
Agree with sci-tech, issue is most likely faulty transfer case. I am replacing one in a ford escape 4x4 vechicle right now. Exact same issue. -
