What can we do about these annoying vibrations

[Agent007]

A friend of mine has been dealing with this vibration issue on their Wagoneer S3 for a while now. They’ve had the car for over a year, and since around July, whenever they hit 80mph or more, the car starts vibrating. They’ve tried everything, swapped out the tires for good Michelin ones, replaced the driveshaft, done the alignment over and over, but nothing seems to fix it. Anyone else run into something like this?

We all have that vibration. Have they tried to "road force" balancing?

Quick tip: Before your friend's car gets worked on, tell him to make sure to double-check that the road force balancer is recalibrated. Many shops might just skip it unless you give them a nudge, and some might not even do it regularly, like once a month! Trust me, paying attention to these little details can really make a difference!

Maybe the problem was with the tires? Try swapping it with a different brand.
