Trailer Floor Repaired and Drive Wheel Vibrations, Keep on Trucking

So this week I have fixed the trailer floor that was sagging. Working on fixing the vibration now with the drive tires. The dat board has slowed down and trucking is pretty slow. But I'm still making out

[@rearspeaker6364]

never align up driveshafts, they'll vibrate like hell! always keep all driveshafts in some form of misalignment, so any imbalance will cancel out.
