Front suspension ?

[lightninmike]

Hey guys
I have an '04 250 psd, x cab, long bed, srw
anyway i love the truck and it pulls great but..... for some reason the left front is lower than the right front. I took a measurment from the top of the spring to the frame and IIRC it was about a 1/4 of an inch lower. Is this normal due to the fuel tank being on the left side? Was there ever a tsb on it?
I guess it isnt really a big deal but it drives me nuts to look at it like that.
Thanks for you help guys and if i left out any info needed let me know
Oh yeah it is a 4x4 with an automatic

I dont think it is normal..Mine dont sag...Id say get a different set of springs....The thing that bugs me the most on mine is the bed isnt as wide as the cab....It lines up on the drivers side but is in about3/8" on passangers side...
