I have a JD 855 1987, i'm building my front end loader.
I have build boom and braket left and right same size etc.
when i'm installing it, the right side of boom and bucket are 1" too low.
Ive cheak with a beam level.
when a check the front frame and i jack it to lever if i cheak the lever of the transmission it's not level.
doest the transmission and cab are adjustable or i have a twisted frame?

Start with the simple stuff first, are your tires air up to the correct pressure? I thought my FEL was out of level by about an inch, it turned out to be a rear tire a few psi lower than the other rear tire....

Yes i have 28 psi rear and 34 psi front

Rather than pressure, use a tape measure to measure to the center of the axle.
MANY people report buying tires that are the same manufacturer, but inflate to different diameters.

I always air my rear tires on my tractors with a tape measure,, not a pressure gauge.

The front tires do not matter, as the axle pivots,,,
