Rear Suspension Question

bino2two · May 31, 2019

2019 GMC Sierra SLT 4x4. While parked I noticed the rear of the truck on a slight angle, driver side lower than passenger side. When I get home and parked in the driveway, I measured the distance from the top of the rear tire to the bottom of the wheel well; found the driver side to be have 1" or so less space in between the top of the tire and the bottom of the wheel well than the passenger side. Took it to the dealer and of course that difference no longer existed. They put on the rack, hooked up to the computer and found nothing. Tonight I see the driver side lower again.

Any ideas? Is the suspension adjusting for something?

Thanks in advance.

Good ole chevy lean.

The fuel tank is on the drivers side, so that side will always rest lower than the passenger side. Sometimes it's not as noticeable but other times depending on how it's parked will show it way more. To me that sounds exactly like what it is.

Had a 2500 that was lower on one side than the other. Irritated me at first, but I soon forgot about it.

+2 on the "Chevy Lean" or in this case the GM Truck lean.

Basically the added weight of fuel in the tank being on drivers side can make the truck lower on that side by as much as 1/2-1"
