I cannot find anything on how to measure the cab height of the truck?
I got the Hendrickson template for the steer axle. And I found the formula to calculate the drive axle but cannot find the cab height information.
My cab still sits slightly crooked even after installing new front cab bushings, rear cab shocks, and the rod with bushings on both ends. Can the air springs be bad? I've been told that both the cab air bags are on the same air line so they should be equal. The air bags dont leak but I've never replaced them and Ive had the truck for about 500k and it is about to hit 1m. If I measure from the left frame rail to the bottom of the cab I get 8.5". The right frame rail to bottom of cab reads 8.75".
I know this isnt a good measurement but you can see the plastic running along the bottom of the cab on the left side is slightly lower in reference to the full fairings on the side of the truck than the right side.
