Urgent leaving for trip with 81 year old dad ‘16 vibrations 35-45mph
Brand new tires. Road forced balanced. Rotated to make sure not a bad tire or rim. Balanced again. Rotated again. Random shake 30s to 40s seems very odd.
No codes thrown. Driving 81 year old dad to Canada did bear hunt. Don’t want to break down.
One shop said could be something minor in tranny or front differential but no way of figuring out just drive it
Two shops inspected tie rods, ball joints, rotors, driveshaft, suspension, all front end can’t find anything
I see newer Colorados ‘17 and up some sort of tranny issue that requires a flush at the dealer?
We leave tomorrow- not much time to hunt this down …
Drive it or rent a truck ?
