I'm going to say the driveshaft. I think there are problems associated
with those aluminum pieces that CC is not admitting yet. The dealer
tells me they've changed the design a few times in the last few years.
That sounds like beta testing with Joe Public in my mind.
On my truck I get a whine under deceleration, much like the sound of a
ring and pinion not properly set up. The dealer tells me its the
aluminum driveshaft and that all the Club Cabs have it. But when I had
the truck in the dealer for a tranny problem at 500 miles, the loaner V6
Club Cab they gave me didn't have the noise. Sounds like I'm getting a
line, though I haven't followed up on it since. Anyone else with this
noise in their truck? Mine is a '98 5.2L Club, with a 3.92 rear end.
