Truck leaning on paseenger side.

I think it's from the extra weight of the DOC, and DPF on that side. It's almost an extra 1000 pounds.

Same on Cascadia.

 

Could be shocks or leaf spring I notice this with heavier people.

 

Truck torque to the right and stress springs common on lots of trucks. Also roads are slanted to the right

 

My truck is leaning to the left, I replaced steer axle springs with - (minus) type leaf spring as was originally. But i remember Nashriza post, he said he prefers the + because are more stiff, i'm thinking maybe installing both +, or + on right and minus left would balance the weight distribution for leaf spring steer axle.
Could come from cab, i noticed my left cab shock leaking every time soon after replacement, once the shock is toast there nothing to hold the cab air spring from over lifting one side, maybe shifts more weight in opposite side, and the cab is quite heavy on 780.
I thinking to get adjustable coil over for cab , they come with different springs from 200 to 4000 lbs mostly for off road applications.. and compress the left or right coil as needed.
The problem is i don't know where to install a shock bracket on the rear of the cab, like most other brands, because is soft tin, i bent it with a jack.
I believe this kind of adjustable coil overs would work for steer axle also, if the truck is heavier on one side ,compressing the coil takes take part of the weight off the leaf springs.
Well , Volvo is not designed for these, the OEM shock like many parts are suggested to maximize their profit not our comfort, but most truckers end up their career with lower back problems. Same ,If you buy a new Jeep, comes with 30$ shocks, want more performance you got options.
Well, just some thoughts, i added to much scotch in my coffe.
A couple of random videos i just searched to see what i'm talking about, but are 100s of brands and coil over sleeve kits that could be adapted for OEM shocks, not very expensive, see Summit racing, 4 Wheels Parts,, .

 

Check your cab mounts they have rubber bushings in side.When they go bad cab would lean to one side about $60 a piece

 

I know this. See the straight truck to the left. It leaned to the left ... until... 6. Suspension & SteeringFront Axles, Rear Suspension ... - Volvo Truckshttps://www.volvotrucks.us/-/.../volvo_section-6-suspension-and-steering.pdf?la... the suspension pads on the rear axle were replaced. They are really hard rubber or plastic. Mine where worned down 2 inches. The link above is goes to the Volvo page. hopefully you can open it.

 

Hey guys. I have a question my truck volvo vnl 670, 2011 it is leaning on the passenger side. I was trying to look under the truck on the passenger side but i can’t find much. The only thing that i can see was on the passenger side, that u-bolt that hold the leaf spring on the driver side it has like a lil metal plate under and on the passenger side seems like that is missing or maybe broken. I will post a picture every advice will be appreciate. Thank you!
First picture is on the driver side and second on passenger.

 

On top of the axle there is wedge then leaf spring then top plate and u-bolt that clamps all this together. Wedge has a different thickness, there’s 20 and 28 mm thickness to them. Driver side is 28 and passenger is 20. Stop at any Volvo dealer ask them for Leaf Spring, Front Suspension to be printed out and you will see how it should be and parts list.
