Hey everyone... i have a question... I installed gears a few days ago, well not personall me... but a guy did... anyways, they make noise as im sure some of you know by now... when locked in the gears make noise on deceleration but when accelerating they are quiet... they only make noise in 4high, because 4low is too slow. This is my problem though, I think that I can still "feel" them turning when I am in 2wd, it is kinda of a whirling/humming/deep vibration... But, it goes away at faster speeds... :think: It doesnt do it slow (about 15-35mph) it does it in the middle (about 40-60mph) but then once you get movin good up around 70 or 80 mph, it seems to "dissengage" and they are quieter... isnt that weird? Is that the speed that they stop turning or when you cant engage 4high anymore or something... and thats why they get quiet again? So for the real question... am i making this up or do my front gears turn while im in 2wd? My truck is a 2003 with the newer transfercase so it doesnt turn in 2wd... so I know power isnot going up there.... but maybe the cv's are still spinning them and they are being noisy? I dont want to hurt these things! But im back up in gainesville, and in a week and a half the guy is gonna recheck them for me.
