how to measure rear end sag CORRECTLY?

[tbomb]

my truck never has had the rear end sag issue, but now ive got this horrible paranoia that its starting to develop it. from some angles it looks perfectly fine, but from others, it looks a touch saggy; i just cant tell, so i need to measure, and ill adjust the torsion bars accordingly.

now, ive tried a search and read some threads about this, but i havent found what im looking for. i plan to measure from the ground (the floor in my garage, since its level) to the top of the wheel well...now heres my question: arent the wheel wells cut higher in the front of the truck than they are in the rear? so how you can tell if theres sag, if the measurement up front is supossed to be greater than the measurement in the rear? i mean, if i make all 4 measurements equal, then when i stand back and look at the truck, itll look like its "nosediving", wont it?

im confused, i need help; please help me! i only have this weekend to do it, cuz i go back to my apartment on sunday afternoon (which is 100 miles away) and i wont have access to a level ground or anything to accurately leasure the sag for a number of weeks.

thanks.

Why don't you take a tape measure and measure from the bottom of the front and rear bumpers?

Ford has an actual procedure for doing this. I think someone posted it before. For the front, it involves measureing from the center of the torsion bar to some other point on the suspension pieces up front. I do not know exactly where or what the procedure would be for the rear. I have always just measured from the top of my wheel well to the floor when mine is parked in my garage which is level. It looks very level to me when I get the front and back as close as I can. You aren't going to tell a 1/4" difference. If you have a 2" difference, you will surely notice it. Just adjust it until it looks right to you.

All you need is a tape measure and a small ratchet with the appropriate socket. Just toss them in the truck and do it when you have time I measured from the ground to the fender flare.

robert and alec, you guys just adjusted the truck so that all 4 wheel wells are the same height from the ground? ill pretty much do what you guys do, since i trust both of your opinions.

thanks.

yeah, I think my wheel wells are the same shape front to back. But if you adjust it and it doesn't look right, it's not that hard to change
