Perhaps a 3/8 bolt would be reasonable for a 2x4? They give a maximum vertical load of 1400 pounds, assuming "a straight vertical lift in a gradually increasing manner". Which a trailer on potholes won't be providing. Hmm.
No lifting load at all in my application. The loading was under the 2x4 causing the load to press upwards on the shaft. Either way the 2x4 (pine) is the weak link. I used hardened
white oak for my wheel runners. Can't hardly drill that stuff!
