We bought the 2018 Alante bought Nov 2027 used at 4500 miles Dec 2021. Original Goodyear tires. We have 8600 miles now, and it has bounced since we bought it.
Alante31, Has yours always done it or something new?

Always.

Got back this evening and vibration not as bad, they did another alignment, seems better but now steering wheel at 2 oclock vs 1 oclock. I can deal with that and will take back after rv trip, as they did not do test drive, probably the steering stabilizer not adjusted.

Will do the tire checks tomorrow. Stay tuned.

it does do an up/down bounce going 35mph down fairly new concrete flat 200’ section of road near our house.

They should have not let it go without centering the steering wheel. It’s not the stabilizer, it is the tie rod end adjustment with the stabilizer loose, then tightening the stabilizer. If stabilizer was where steering wheel is correct, then it would be sending you toward the ditches. Mine was wrong, and they re-did it. One front end alignment should last you 75000-100000 miles. If parts wear out then that’s a different issue.

I see that in campgrounds all the time. I know you’re not supposed to. Then get out there and Grab the top of each wheel and push and pull on it. You’ll know right away if you have a bad wheel bearing. As I said above mine went bad at about 6000 miles from the factory brand new.

Ok, you and Kevin might be on to something.

Both driver & Passenger side have a bit of give when I pull on the tires, say maybe 1/8 of inch if that. Think bad wheel bearing still?

Also both have run out but the passenger side seems worse.

Pics attached of these awesome G670’s.

What ya’ll think next step?

Here are pics of steering wheel with fronts off ground, running engine and turning wheel all to the right and return and then all the way left and return per the steering stabilizer. Should be back to center correct?

In general, with steering wheel straight the tires are pointing center/straight.
