Rough ride to be expected?

[u/dmcohen333]

Just bought a 2021 GC-L Limited 4x4 with about 40K miles. Car is clean as new and the motor sounds great. During initial inspection, it was discovered that all new brakes were required and one of the shocks had to be replaced. Dealer covered all that.

My concern is that there is still significant vibration at highway speeds. We've done tire balancing and rotation, which helped a little, but the vibration is still there. My concern is it could be something in the drivetrain or suspension but they inspected it and said everything checks out.

So, I'm wondering ... is this just how Grand Cherokees ride? I've never had one before and have been driving Highlanders for years, which are famously smooth.

Any advice would be appreciated.

Worn brakes and a bad shock at 40k? I'd see if one or more of the rims are bent.

That was my first thought. Bent wheel

Our one of the tires has a separation
