I am trying to find a good way to tell how much / if my front springs have sagged out in the last 250k miles. It rides very harsh, and I am looking for a good reference to measure. I am running stock size tires. Ground to fender lip or something like that would be much appreciated.

Don't have 94, but 97 should be the same, this is frame dimensions, might help.

Interesting - what measurement scale (millimeters, centimeters, inches, etc) is that based on?

When I broght my truck home in Sept 94 I measured the front where the wheel well starts to turn under in the middle of the rim 34 1/2". rear 37 5/8" with stock tires still the same today 117K. Its on my shop wall.

Pretty sure it is MM

Thank you. That should do nicely. I am expecting to find them sagged quite a bit. Any idea if the measurements are with or without fuel?

Pat, I don't think it is millimeters (or even centimeters) - at least, not in all cases. If you run those measurements through a metric/English conversion, you don't get reasonable numbers for some of the dimensions.

For instance, the "100" dimension from the bottom of the transmission crossmember - 100mm is 3.94 inches, and 100cm would be 39.37 inches. Neither is reasonable for a crossmember-height for a stock 2WD. However, the "913" dimension between the mounts on the outside of the front frame horns converts from millimeters to 35.94 inches, which may be reasonable. Maybe a different basis is used for height than width? Or maybe the ground isn't the starting point for the height measurements?

That was my conclusion as well, perhaps a factory jig? In any instance, I would take the relative difference at 2 or 3 points and compare them with my actual, so if front inspection hole is "Y" above rear spring mount, I would call front measurement rear actual ht. plus "Y".

Thanks for clearing all that up guys. I was wondering how my truck was 5 inches taller than it was supposed to be.
