Twisted frame question...

I sighted down the cross rails and noticed a twist. Using a level i figure its twisted about 2 inches. The framerails themselves are flat, albeit the right back end is lower than the left back end. Something I can correct, and if so, how? My floor is stone and uneven. Could this just be a natural twist that occurs with this length of vehicle?

It's tough to tell from your pics but the first thing is to get it on a level floor . The next is to get it on even jackstands to eliminate any spring sag or wear and then look it over . Twists are not uncommon on long wheelbase trucks and shouldn't be too difficult to correct .

I think it was the springs. As soon as the wheels came off and put up on the stands it flattened right out. Thanks again EB.

EB, couple people called and messaged asking what else I found with the frame twist.


Three of the large rear spring keepers had broken bolts across their tops. The fourth was intact and keeping the leaf springs sandwiched together. I took a measurement from the bottom of the frame to the top of the leaf pack and saw a difference between the driver's and passenger's sides. I cut the remaining keeper and the axle dropped down to match the other side. The second photo shows the front spring culprit. All four keepers here were intact, but this front keeper was leaning forward about a half inch. I took a hammer and tapped in back in place. Everytime it moved back a little the front axle would drop down on the high side. I gained about a whole inch even though the keeper moved half that amount. The measurements are now even all the way around. Mystery solved.

​​​Enjoy your evening.
