So Im trying to diagnose a problem that just started happening on my 02 F350. When Im on the highway, between 55-70 mph and I let off the throttle and keep it on lightly, around 1200 RPM I have a wierd whistle/harmonic grinding noise....very hard to explain. First I thought it was my turbo, but have pretty much ruled that out. Im thinking drivetrain now...
Am I correct that in 2wd the front driveshaft does not spin? It engages in the t-case right? If thats the case, Im thinking carrier bearing or ujoints. Moreso the carrier bearing because it sounds more like a grinding...metal on metal noise.
I have about 3K on the new 8" superlift suspension kit. I have vibrations and need to work out the pinion angle...
Any other thoughts? Places i should look? Wish I had a better way to describe the sound...
Thanks!
