Axle nuts

you can use a cheater bar. first, clean up the outside threads with a with brush.
a plumbers trick i learned was to try and tighten them first. not hardly at all though, then back up.
make sure it's setting on the ground, also, plus in gear. i think, reverse.
my cheater bar, was only a yard long. 36".

now that i think about it some,,. i have a socket, 19' strong arm, plus a cheater bar, and i might have stood on the cheater bar,, and may have applied heat also. :smile
i did clean the threads 1st.
did i use penetrating oil?,, probably so..

i used a b.f hammer more that once. just not on an axle nut. maybe on my thumb once. it didnt help my thumb
you can find b.f products at any store.
