tires...
Getting a drive shaft ballanced is not expensive... But I'd look into new tires first seeing how that's what you changed last. As far as the cal tracks causing the vibration, that's just silly.
Sounds like you need a new tire dealer
Well 1st rule out the TC, and get to that speed and drop a gear and see if it's still there...
If it is see a shop with a balancing machine, what state are you in it's not on your profile?
Got anyone you can swap tires wheels with? Rule that out since thats when it happened
Central Illinois, just west of Peoria.
Things are defiantly better after the RF balance, but before I had zero vibrations.
Tried dropping a gear @ 40, 50, and 60mph, still vibrates just @ a different frequency. Went on a little road trip, pulled a fairly long hill @ 60mph in 3rd @ around 2500 rpm, it still vibrated even with the rpm's up. Let it shift to OD and more of the same, just a different frequency.
So since the frequency of the vibe changes when the speed of the truck does not doesn't that point to the trans rather than the driveshaft? At the same mph the drive shaft isn't spinning any faster.
That's why i wanted you to drop a gear, rather then make you waste time in the wrong area with something it's not
So you know its not tires and you need to start lookin at the trans and tc
