Tweaked Frame

I've had my truck with the bed and front clip off for a while now and just recently checked the straightness of the frame. I jacked up the front to level and then checked the back and I am down about an inch. It is progressive it doesn't just drop at one point. If I level the rear then the front is out. So what I'm wondering is if these frames are known for being a bit out or if I've got a real problem. I don't see any signs where damage might have occurred or where someone might have tried to fix it. Thanks

Re: Tweaked Frame

I'm not sure which level you're taking

Are you talking parallel to the frame rail? I doubt the front and rear will be the same

If you're talking perpendicular (one rail to the other) theres a lot that could be throwing it off... tire pressure, shocks, spring sag

Level isn't straight

I am not quite sure what you are doing from your explanation but I would venture a guess that unless you are 100% sure that whatever you have it sitting on is perfectly flat that it could easily be out 1" on any given corner in the length of the frame.... Do you have jack stands under one end, then measuring the other end?

Re: Tweaked Frame

I have the front end leveled using a jack and jack stands the back the same. I talked to someone today that led me to believe that the frame might not be as structurally sound as I thought and to wait until i have everything bolted to it to tell if its bent. I bolted up the cab today just to see and it has moved it a bit. I will have to wait to see if mounting the bed to it (when I have one) changes the way the frame sits and go from there. I didn't want to wait to that point but I guess I have no choice. Thanks.
