When my truck is sitting still on a level surface and I look at it from the rear, the left side sits lower than the right. It looks like is mainly the bed and not the cab. Any thoughts on what might be wrong?

Thanks,

The Gas tank is on the left side that could be the reason.

 

It is the location of the gas tank. The sag is less when the tank is empty. The dealers put a spacer in under the left leaf spring to level it out because there's been many complaints.

 

Mine does it too. I'm planning on taking it to a local spring shop this summer to be looked at. I have a hard time believing it's just due to the weight of the gas in the tank. I see a lot of trucks that don't lean to the the side. If that's all it takes to make the truck lean, then in my opinion the springs are way to soft.

 

Black Truck- I agree with you. I am going to eventually get completely new spring packs installed when I lift my truck. If it is the springs that are sagging now due to the fuel tank than they are too soft. I just noticed mine doing it about a month ago.

??? My truck was 1/2" lower on the RIGHT side, front and rear. Tightened up the "Roadmaster Active Suspension" spring in the rear, A few turns to the torsion bar on the front ... and she's level again.

 

Is the "Roadmaster Active Suspension" something on all F150s and if it is can you share a quick note on how to adjust it?

Thanks,
Kevin

 

No not factory, it's a Mod.
