98 frontier 4wd clutch/pilot bushing

can someone please help! me,my truck had the pilot bushing replaced years ago under warranty. well.it's making the same noise again and I figured if I have to have the tranny removed just for the bushing I might as well have a new clutch installed why they are in there. does anybody have a ballpark figure what this will cost me? p.s. I wont be going to my jerk dealer for this! thak-you Dave A.
