If the safety chains are not attached, there are reasons why. If disconnecting trailer hitch from the tow vehicle on an incline without the chains still attached the trailer can roll backwards or downhill into the back of the tow vehicle. I have seen damage and injury over the years as a former dealer who also designed trailers. I never detach the chains until wheels were chocked.
As for chains, always with the hook pointing upwards to hole in trailer hitch vs other way to prevent hook becoming detached. Shorten chains by twisting and criss crossed to prevent to much sway should the hitch come loose from the ball.
If there is no safety chain in Winch stand
add one in the event winch strap break. If chain too long, twist to shorten so it will not hit bow when attached to bow eye when being towed. After going 10-20 miles pull over and check tie downs and hitch attachment. As for hubs feel for warmth because too much heat indicates issue with brakes/bearings-racers/lack of grease
