a little back ground, we have an 06 dodge std cab 3500 dually 4x4 with the g56 trans, a few weeks ago i noticed a really bad vibration at idle, felt like an injector miss. after a little research i determined it was the dmf and clutch. well we replaced the clutch with a south bend dual disc and smf. now the truck feels pretty good. no vibration idleing, and runs nice and smooth up to about 2000 rpm (i didnt go any higher). on the test drive i noticed a really bad gear grind/whine noise during accel. rpm didnt matter too much but it was worse around 1500 rpm and only during acceleration. since the dmf issue ive been poking around for more info on these trannies in general. what i found, and most of this from some literature that came with the sb clutch(i trust south bend very much they have always been good to me) was the damage the dmf can do when its failing. they also included a phamplet about the stiffener girdle. well when i got home i crawled underneath the truck and checked the driveline, everything feels tight and in good shape. my questions are as follows.
one, did the 06's with the single piece steel drive shaft have any vibration issues (all the problems i have read about have been the two piece)?
two, did the third gens have a driveline damper like the second gens(the one right at the tcase on 4x4's)?
three, does this grind/vibration noise sound like a trans problem that was refered to in the literature (should comment i noticed the same noise when i shut the engine off after idleing in nuetral for about a minute)?
lastly, who has put the girdle on, what do you think of it, and what problems have you(with or without girdle) had with the g56 trans. this truck tows 90% of the time, empty trailer is around 6k, fully loaded it can be as much a 25k gcw.
