GMC Yukon Denali with stock 22s

[Autowholesale]

2016 GMC Yukon Denali 22”s rides like a 3/4 ton truck. My understanding this ( should ) be a smooth ride. This is not a XL. Miles are 105k

Tire inflation pressure is very important and will need to be adjusted with seasonal temperature change. Hot tire temps above 37-38 PSI will result in lumber truck tendencies. Also, check to make sure your magnetic ride shocks aren't frozen up - That seems to happen when they get old and worn out.

Thanks for heads up. I’ll adjust tire pressure today. How do you tell if shock are frozen? So many variables on this vehicle, suspension control module, compressor, shocks. I’ll start with pressure and go from there hopefully without to much $$

All tires set to 35psi per sticker in driver side door jam. Same really hard ride

Check your struts/shocks to see if they are leaking. Also try an see if one side/corner is lower than the other. Good indication that it maybe locked up. At 105k I would assume the magnarides have been replaced before. Are you the original owner?

I second a strut check. Measure all 4 corners... stand on running boards and jump on all 4 corners to check suspension cycles, or jack up each corner and you should see the suspension droop/relax. When my front right seized up, it was incredibly rough, jumped on that corner no movement, jacked up rig and the tire/fender clearance did not move at all/droop out... all other corners did. it had ZERO movement.

Look for oily reside on the front struts like mentioned. I had my factory ones replaced at 84k under extended warranty for oil leakage that was staining my garage floor. I didn't realize how bad the others were until the new ones were put on - rode like new again. 2017 Yukon Denali

Thank you to all who responded. Just purchased from original claims vehicle always had hard ride, not sure about that. Rear of vehicle sits about 2” higher than front, does not appear to be anything leaking, pulled air supply line off rear very little air came out and height didn’t change.

Mine is on factory 22's and ride is in no way considered "harsh" driving on multiple poorly maintained roads in our area.

They are built form the ****** with a mild suspension offset, what’s called “rake” to make for better aerodynamics to help meet EPA fuel requirements. Front sits a rad bit lower than the back. All GM SUVs and pickups are this way from the factory so this is normal for your ride to be setup this way. From what I’ve learned even if the shocks aren’t leaking than can still be frozen up and cause a rough ride. Have your suspension check out first. But also make sure your tires are still in good shape. Flat spots in the tires can contribute to a rough ride.

Remove the wires connectors to the shocks test drive and report back. By removing the connectors you are eliminating the magna ride of the shocks. They should ride like normal after you unplug them. You will get the service suspension icon, disregard the message for the test.

How many miles are on the suv?

Will do tomorrow at shop. Thanks you

If ride softens up what might be the fix ?

I used to have 2016 YukonXL SLT without magnetic ride on 18” wheels and had installed Michelin tires, and my friend had Denali XL on 20” and Michelin tires.
I drove my friends Denali and it was not much difference.
From threads about harsh ride, I know many downsized from 22” to 20”. And also I believe Michelin tires are little smoother. The 2015-2020 had harsher ride than 2014-older; and it looks like they made it better in 2021 and also added independent rear suspension, first time for GM large SUV.
I currently have 2021 Suburban RST without magnetic ride and on 22” and it rides pretty nice! (I originally was looking for 20” when upgrading from 2016 due to harsh ride complaints for 2015-2020, but with short supply I ended up getting RST on 22” and now I don’t think I want to downsize to 20” because it rides pretty good)

I can attest that my HC Suburban with magna ride + air ride suspension is the most comfortable of any other vehicle I've ever driven to date, I'm sold on those features

Dealing with the same thing on my new to me 2018 Denali. Changed the 22’s to 18’s didn’t help at all. Dropped it off at the dealer this morning. We’ll see what they say. Rides way worse than my 3/4 ton diesel truck.
