OT mechanics: 2015 Suburban rides like a tank

That vehicle shouldn’t ride that rough. I would suspect the wrong or overinflated tires or something like that.

Is this your first full size SUV? Like the other guy said, it is a truck frame with a family hauling body bolted on it.

Test drive another suburban to compare.

I called Arnottindustries and they only offer rear struts for this year vehicle.

WTF



You don't know much about trucks, do you?

Does it have large OD rims and low profile tires? If so that is your problem.

I looked at the vehicle briefly, drove it a little and it was pretty late.

I am gonna check it out a little more closely tomorrow.

To be continued...

Replace the shocks with something good like Bilstein and also check your tire PSI and find what rides the best.


eta: The DIY would probably take an afternoon if you're somewhat mechanically inclined and have the time. It will probably save you $400 on installation.

Replace the struts and shocks.

Suburbans are known for being very good riding vehicles. Something is mostly wrong.

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.
