M353 Trailer Chassis Landing Gear Wheel Help Needed

[NOLATAC]

Hello all. Recently traded for the pictured M353 trailer to build into a welding/tool trailer. One of he front landing gear/jack wheels has the spinning wheel to lower and raise it frozen. Any guidance on how to get it off or unfreeze it?

I have drowned it in WD40 to no avail. I am in the process of changing out the zerts to try and grease it, but thought I might want to take it down and give it a good clean, but cannot get that big nut on the top of the cylinder off.

For stubborn stuff we have used pur acetone and automatic transmission fluid in a 50/50 mixture. It has worked better than anything else we have tried.

You can always heat it and whack it with a hammer too.

Heat, heat, and more heat. I have repaired a boat load of these generator trailers. Soak it, like Bradley wrote. Then heat, and reheat. I used a BIG pipe wrench, and a cheater to get those nuts off.

X2 on the heat. !!!!!

Unstuck lots of farm equipment and such with heat and the 50/50 mix as mentioned above.
Liquid Wrench works fantastic also.

And to be more specific, WD40 is a terrible penetrating oil. It's better than nothing, but not much.

WD-40 was not made to be a penetrating oil. It was made to displace water.
