Need a lot more info. Suburbans usually ride great and should not need any aftermarket suspension. The usual things you can do to change suspension are add spring spacers and swap shocks (usually aftermarket shocks are more firm and heavy duty for offroad use), neither of these things will dramatically improve the ride of an IFS vehicle over stock.

1.) what is the tire pressure of all tires?

2.) what size are the tires?

3.) what is mileage of the vehicle?

4.) is everything stock?

If everything is stock and tire size and pressure is normal, I would bet you are getting up there in miles (over 70k) and the front magnetic coil-over struts are bad and probably need to be replaced.

Why fuss with it? There are thousands of ‘15 Suburbans and Yukons out there. Just get one that doesn’t have a potential mechanical issue

Sounds like Op has tunnel vision which usually means the buyer gets Fd

Looked a little closer at the vehicle.

Tire pressure checks out good, appears to be stock tires(R20s). No LTs, basic road tires.

Mileage is a little higher than I thought, 122K.

Everything looks stock.

Called the GM dealer and they looked it up the VIN and the vehicle DOES have magnetic front struts, about $650 each.

Told owner that if he fixed the issue, we will talk.

Otherwise I am walking.

Thanks for the info everyone(except Crusty the Clown).
