My humble 20ft trailer has four BAL "lightweight" stab jacks, made from the cheapest steel they could buy. Despite BAL's boastful rust resistant e-coating claims, the jacks are fully rusted and almost impossible to turn.
I used an impact wrench to try and free one up and only succeeded in damaging the drive ears at the end of the screw. these jacks have no socket end, just a squished piece of soft steel that slots into an equally cheap wrench.
I'm going to replace the jacks, likely with the same thing as my trailer is very low slung and there's not enough clearance for nicer scissor jacks.
What can I do to keep the rust off this cheap steel? If I grease or oil the metal, it picks up sand and gravel from the road, and that jambs up the works as bad as rust.
