Driver side lean - lean to the left - Chevy Lean (combined threads)

Does anyone else have a Chevy lean going on? My truck is about an inch lower on the rear driver side of the bed. I measured with the tank over 3/4 full. The front is even. I've got an extended cab two wheel drive with the V6. My Silverado had this symptom as well, but it was 10 years old when I got it. Makes me wonder how low the drivers side will get when the truck is older. Anyone else have the same lean? Am I just being paranoid?

2016 Driver's seat lean?

Measure other points to ensure you are getting accurate measurements. One bed side may be lower (like not mounted properly). Or things of that nature. Park on a level surface and put a level on the bumper. Or compare the angle of the surface with the bumper by placing the level on the surface and making it level if it isn't....measure the distance you must raise one end of the level to make it level. See if the numbers agree to also set the level to be level when on the tailgate. OR bumper...or whatever.

See if every variable you come up with results in the same lean to a side.

I have not seen the design of the tanks, but it seems a bit unrealistic for one since of the truck only to carry the weight of the fuel. Especially with current government requirements for the tanks to be out of harms way in the event of a vehicle impact from the side.

Thanks for the reply. I've measured the truck in multiple places and used a level. I even did this in a different parking lot then I normally use. I always get the same result, the drivers side is a bit lower. Sometimes it will change slightly, but it's always lower.

The gas tank is on the drivers side only, even the spare tire is not centered and is slightly on the drivers side to make room for the exhaust. I assume this is why, but I wanted to double check with everyone and see.

Willasan, I think the only solution is for you to start dating a significantly bigger woman than you. She could even out the tilt. Or a prerunner tire mount on the passenger side.

Joking aside, the issue has to only get worse when you sit in the driver side too. Most cars suffer from this, and I had similar issue on the Jeep and Titan.
When I install my adjustable springs, I will have to compensate for this. How much is your lean? is it worth a single 1/4" shim?

I've got about approximately an inch of lean to the driver's side measuring the at the rear of the bed with a full tank and my normal stuff in the cab. The front is pretty much even. If it's normal, I'm fine with it. Just wanted to check.

Pick Up Bed Uneven

I was looking at my truck the other day from behind and it looked like one side of the box is higher than the other. I measured today, and sure enough the rear corner of the bed on the drivers side, is an inch shorter than the passenger side. To be honest I do not know if this is a leaf spring problem or what. I know it is abnormal for a new truck that has never had anything loaded in the bed.

Any ideas on what I should look for?

I am taking her in for hood flutter Tuesday and would like to have better idea of the potential cause of this when I drop her off. Any and all input is appreciated.

TIA

Only time I have ever seen this is like you stated... On an old truck that has been used for heavy hauling.... Start by checking all the bolts that hold the complete spring and the shock on that side.... A place to start anyway... Good luck finding it !!! Got to be something simple. IMO

Just asking, but wouldn't the suspension (leaf springs) on the left side have a slightly different rating to allow for that? I realize a full tank probably only adds approximately 150-160 lbs including the tank, but an inch is quite a bit don't you think? And really, I'm just asking I don't know if effort is made to offset the additional weight of a side mounted fuel tank, but again 1" seems like a lot?

The general answer is , No. It might seem logical to do as you suggest, but I have never seen anyone do this.

If you think about it, 90% of vehicles probably spend 90% of their drive time with just a driver, no passengers. Would probably make sense to mount the fuel tank on the right side to counter some of this issue, especially if you don't mount the fuel tank in the center. (Obviously, with a rear wheel drive or All Wheel Drive vehicle, a drive shaft kind of gets in the way of a center mount fuel tank. )

And yes, my 90/90 % statistics are a number pulled from the air with no scientific basis for their derivation.

Are you parked on a completely level surface when measuring?

There should be some bushings between the bed and the frame. Crawl under and see if one is missing. It's a thought.
