it is not rocket science.

First of all, measure the front cab height between the top of the frame rail and the bottom of the cab on both drivers and passengers sides right behind the front cab mounts. - They should be equal height. This is a problem with prostars, as the drivers side will slip (it is designed to do so) if someone has hit a hard enough pot-holes or is driving like a freggin maniac 70+ mph everywhere and letting the roads beat the crap out of the truck all the time. The drivers side cab mount is adjustable. A person also needs to observe the correct torque specs when adjusting it and tightening it back up so that it can slip again if the truck is hit hard so that cab damage does not occur.


Then, measure the top of the frame rail to the bottom of the cab at the back corners. - this should be the same height, or slightly higher than the front, and they should be fairly equal depending on how unevenly balanced the junk you got inside the cab. When I installed my pro-ride system, I took all my tire chains out from under my bunk, installed a chain hanger+the chains to my passenger side on the frame rail itself, so that the extra weight would not be in the cab.

ASLO--- just as important ... put the truck on a shop floor/level place and measure the bottom of the frame to the ground on both sides in the front and in the back. - If the frame is not level with the ground because you have a weak spring, then the whole truck, and especially the cab is going to lean.


-- Like i said ... not rocket science. Measure and find the errors.

#1 cause of leaning cab on prostar is that front cab mount has slipped down or is out of adjustment.

#2 is weak springs in the front of the truck and frame rail is lower to the ground on one side, makes cab lean harder to that side. - If you have one of those gawd-aweful hendricksion air-suspension front ends, the front levelling valves could be set uneven. Again, the bottom of the frame to the ground is how you get them set properly.
