Proper Jacking method for dual axle trailer

[kend40]

Hi all:
I have had my trailer for 3 years and it just occurred to me that the day I get a flat or need to change a wheel, I don't know the proper procedure for getting just one wheel off the ground safely to change to my spare.
I know someone on this forum can properly explain this procedure to me, and will appreciate the assistance.

I recently bought a dual ram bottle jack. Collapsed height is only 7" and extends to 14" and will fit under an axle with a flat tire. Regular bottle jacks are too tall. $23 on Amazon. If jacking up an axle, you must be very careful not to damage anything - use a block of wood on top of the jack. Can also be used for doing your brakes and bearings at home.

There are other methods like using the Anderson leveler ramp to raise an axle high enough to get the wheel off.

I haven't jacked a two-axle, ever

More or less just like your car. I carry a bottle Jack for such an occasion. I had to actually use it once and it worked just fine for me.
