When shifting into 4-wheel drive and turning there is a noticable clunking noise

Check for a shop in your zip at the top of this page. ( find a shop) In reality that is the only way to find this noise!!! Been doing this for 42 years so....! Save yourself some money, have it checked! I will add if doing this on dry pavement, it could be quite a few things! Puts a lot of strain on the 4x4 system!
