WTF??? Of course is will affect the springs, it adds more load to that side of the truck and thus compresses the spring more. "Connect" another 1,000 lbs to the drivers side frame rail and see if the thing sits level. You have ~200 lbs of fuel, ~50 lb t-case, driveshaft, etc on one side plus a 200lb driver. It isn't balanced left to right thus it will not sit level. It is common to mount the light exhaust system on one side and the front driveline and fuel tank on the other. Its the easiest way to make it fit.

Search on the FJ cruiser forums for "drivers side lean" and you will find they too have the same problem since Toyota mounted everything on the drivers side. Is it a design issue? yes. Is it a reason to lemon law your vehicle, no. The only way for automakers to overcome this is to put heavier springs on one side which causes handling quirks which will cause more complaints.

Have the dealer confirmed your tires aren't bad and that your rear axle is straight which would cause the cupping. The drivers side lean IS common and if you are really concerned about it get some trim spacers for the drivers side.

 

Just because its common doesn't mean its correct or intended. Lower on a front can cause a whole array of issues in an emergency manuever.

 

you clearly have zero understanding of what you think is a concern. your suspension would have to be completely worn out springs broken, to affect your truck.

what you seem to think is a problem is not you just want it to be for what ever reason.

and you measuring at the bumper or the wheel wheels is not how you measure ride height, i shouldn't post this put here how you properly check ride height, i will guarantee that know one has done this.

Front Ride Height Measurement



Item Description
1 Ride height = 2 -3
2 Measurement 2
3 Measurement 3


NOTE: Make sure that the vehicle is positioned on a flat, level surface and the tires are inflated to the correct pressure. Vehicle should have at least one-half tank of fuel.

Position a suitable surface gauge (such as Starrett 57D Surface Gauge) on a flat, level surface and adjust the gauge arm until the scriber point is located in the center of the rearward lower arm bolt.
Lock the surface gauge in this position.

With the surface gauge positioned on a flat, level surface, record the measurement of the surface gauge position (measurement 2).

Position the surface gauge on the same flat, level surface as used in Step 1 and adjust the gauge arm until the scriber point is located at the lowest point on the wheel knuckle.
Lock the surface gauge in this position.

With the surface gauge positioned on a flat, level surface, record the measurement of the surface gauge position (measurement 3).

Subtract measurement 3 from measurement 2 to obtain the front ride height.
Refer to Specifications in this section.

Rear Ride Height Measurement, All Vehicles



Item Description
1 Ride height
2 Rear axle jounce stop
3 Top of the rear axle tube


NOTE: Make sure that the vehicle is positioned on a flat, level surface and the tires are inflated to the correct pressure. Vehicle should have at least one-half tank of fuel.

Measure the distance between the rear axle jounce stop (Item 2) and the top of the rear axle tube (Item 3) to obtain the rear ride height (Item 1).

 

I didn't know we had so many Ford engineers on this website.....

 

Assuming its suspension relatet. What if its defect in the frame. Ford is sending in an engineer on 9/28 to look. Either way frame or suspension, its still not right and does affect handling and braking. True, alignment can compensate, but additional stress is put on one side would throw off that alignment faster than if it was equal. As for the cupping, it may be a defective shock absorber.
