Vibration at 80 mph+

[nc138]

Anyone notice a slight vibration at 80 mph? The truck is quiet and smooth but as it approaches 80 it seems to start vibrating slightly. If you have a drink in the cupholder you can see it shake as well as feel it. I think it can be a tire out of balance, not sure if the dealer will rebalance the tires.

Tire balance. Or driveshaft vibration issues

Good thing 80+ is only legal in Texas anyway

Start simple with the tires.

I do not have vibrations over 80 (was just on the 130 which has posted limit of 85)

Like the others said start with tires and move on from there.

The rims are OEM right?

The windshield wipers don’t work as well over 100mph but I don’t have any vibrations.

as a texan...i very often pass through 80, 85 i had a small vib in the cup holders right after i got new tires. took them back and the tire guy re balanced them. so far so good

Thanks for the feedback, I’ll get the checked and balanced.

What kind of drink? That might make a difference... (Sorry not a help)

+1, that's where I would start. Possibly a rim weight got thrown and it only shows itself at certain speeds; take her up to 90+ and see if it goes away .

I have a 3rd gen that very noticeable shake only at 80 to 85 but smooth before and after.
Been rebalanced a bunch of times, been aligned by multiple shops, even with high speed balancers. Still there.
I've just chalked it up to some harmonic spot in the drivetrain. Another friend of mine had same issue on his minivan (I know zero in common with truck), the dealership replaced both axles and the 80mph vibration went away.

mine does the same starts about 79 has a new set of bridgstones 20" first vehicle i ever had with 20" firestone is going to do a road force ballance on them . Thinks this will stop it in Tennessee 80 to 85 is the cruising speed on the interstate its crazy. I have a 65 ford f100 that will cruze comortable at 70 but want drive on the interstate in fear of being ran overk

Make sure to get them road force balanced. The tolerances on new vehicles require a narrow band of variance esp at high speed.
