It seems to me to be loud. but it has oil.. 75000 miles on it.. maybe its just the speed it spins with the short tires and tall gears.. 456 and a 235/85/16

The 205 is gear driven not chain driven, so there will be that noise unless it's different than normal to you. Check the diffs also.

What rpm are you at?
