Hello, I have a 2005 F150 XLT Texas Ed. 2wd with a 2.5" leveling spacers and 2.5" rear Blocks with stock 17" Xlt wheels (grey and silver) wearing 315-70-r17 BF MT TR.
The problem is I noticed my right side of my truck sits .5" lower then my driver side does? I measured distance between each sides wheel well to tire a found that it was exactly half an inch difference. I do have Bilstien 5100 adjustable shocks but both are at "Stock" setting? Both upper Control arms are less then a year old as well as lower ball joints and tie rods ends. Could my lower control arm on one side be stuck? I just don't know what the heck it could be? Thanks for the help and both tire PSI is the same in the front. Here is a pic if it helps.

 

Your fuel tank is on the drivers side. With a full tank of gas you could lean almost an inch.

 

Except I think he is saying that his passenger side is the side that is sagging.

 

My truck sits 1" lower on the drivers side with a full tank.

 

Sounds like its time to fill the truck up and even it out LOL

 

Ok, So this is normal? Ive had the Truck since 07 and never noticed it, I currently am low on fuel and will go get gas at lunch today and see if it brings the driver side down to the passengers level lol, thanks guys.
