Bent chassis

[HANCOCK]

I have a slightly bent chassis I believe from welding on spring mounts without having my truck supported well enough

. Its an FJ73 and I have the will and the ways to get it straight but am unshore on where to start to check and measure it for straightness. what is used for a reference to start to check from. No I neither have cash or the desire to take it to a smash shop to have them fit it close enough is good enough in my book I just want my doors to shut properly again. Anyone in the industry got some incite and or done this before?

Thanks Nathan

You think you distorted the chassis by welding on spring hangers??

Stranger things have happened, but I seriously doubt it.

I did a shackle reversal with and put a 5 mm plate on the inside of the chassis on both sides to brace the mount and boxed in the mount back to the chassis to strengthen it up. But when the old mounted where cut off and the new welded on the truck was only on two jack stands just in front of the gearbox cross member and so all the weight was hanging over the front so when this was all done it must have pulled down on it. Yes the doors still shut with a slam but the top of the door hits the window frame.

cheap fix = adjust the doors?

Yes I know that but then the doors don't seal and the catch will not line up. But I be much happier to fix the problem then treat the symptoms.

Park the car on some flat level clean concrete ground, get a plumbob (weight on a string) and mark from some factory positions along the chassis such as spring hangers, body mounts, engine mounts etc down to the ground with chalk. Make the markings all the way around the vehicle.

Drive the vehicle away, draw in a perfect center line followed by all the diagonals. Where the diagonals intersect should be close enough to on the center line.

If not, you can see the distortion in what angle and area of the chassis then go from there
