A section of a cross tie chained between the axle & frame of a trailer will get you a few miles if spring leaves are broken. Years ago the shop I worked in did this to a tractor to get it to the deadline while waiting on parts. Somehow it got hooked to a load & the driver drove it several miles before he realized something was wrong.
Nothing quite like that to show you did a thorough pre-trip. Haha.
Had a driver hook to a trailer that had a brake can caged...never noticed it till he got back in the yard. DOT would have LOVED that one.
