I have a new '06 luxury package with the Torque On Demand(T.O.D.) four wheel drive system. It has a vibration at about 75 mph and I am wondering if this is due to the T.O.D. or something else. It has less than 1000 miles on it so yesterday was the first time I ever hit 75 mph. Any Ideas? I was thinking mabye it was just a balance issue on the tires but am not sure and live 1-1/2 hours from the dealership.
unlike the part time 4wd your ft drive shaft turns all the time (part time 4wd does not, non lx package)
so it could be either or both driveshafts or tires or transfer case or differental pinion angles just to name a few
i don't know if i have ever had my ex up to 75 mph, but i have no vibrations, but have other serious issues yet to be resolved
if you are mechanicly inclined i have a question for you and any others with 4wd. when you have your skid plates off grab the inner right half shaft joint (from the ft differental) and see how much verticle play there is in it, mine i can move up and down at least 1/8 of a inch and make it bang in doing so. this it would seem would cause a noise or vibration at some point ?
