Thanks for your replywhen it was brand new my 2001 had the same miss match at the front of the bed, the drivers side was higher.
it's still that way.
to check the bed for straightness run two strings between opposite corners forming a big X.
get them real tight, they should touch in the center.
try it both ways, that is alternate which string is on top.
you can check the floor too, run the strings on identical blocks, extra helping hands preferred.
a frame machine is a big & precise rack. the truck is placed on the rack at specific factory mounting locations.
the rack needs setup for each specific vehicle, it's time consuming.
then measurements are taken and compared to published factory numbers..
if needed big chains & jacks are used to bend the frame back into specs.
try for some pics at the front of the rear springs, that's where the front & rear frame sections are joined.
yes, that year Ranger has 2 distinct frame sections, front & rear. they are held together by rivets at the front spring hanger.
just crawling underneath with a carpenters level may reveal what's going on. Park on flat 'n level pavement.
The cabin of the truck is sticking up it seems as well as the bed so something is going on. I was going to order a body mount kit and the bed hardware. But i am unsure of what kit to buy for my truck.
I still think the frame is bent under there some where. My plan was to go back to shop that has the frame machine with the body mount kit and ask them to fix my truck body. If there correct and my frame isn't bent they should be able to do it. If there wrong then they will fail to fix my truck and then i can ask them to put the truck on the frame machine and unbend it. I want to save the truck. Wondering how much it is to unbend a truck frame? I will ask that shop.
I will get photos of the truck on Monday on a lift
