just boughy a 98 dakota r/t and I am now noticing a weird noise coming from the differential whenever I take a right hand turn. I can hear it fairly well when I sit in the cab. should I be concerned? it has 80,000 miles

I would personally have it checked out. Dodge is known for drive-train probs...hopefully its nothing bad but do it quick if you still have warr. Good luck. Just to check yourself, I would just check to make sure lugnuts are tight....
