Jack location for changing a trailer wheel ?

Subject: Jack location for changing a trailer wheel ?

What is the proper location to place a jack under the trailer when wanting to change out a failing wheel and/or its tire ? I've read the EZ-Loader manual for my trailer's single axel and there's no mention of where to place the jack. It probably is self explanatory but do wonder if there's a proper place vs. a wrong place for the jack. For cars, there's a specific location for a jack, so why not for a trailer ?

Thanks... 🙂

Correction... I have found a section in the EZ-Loader Owner's Operations Manual on page 24. There's a section titled "Jack Placement". 🙂

On my aluminium I-beam EZ-Loader the jack should be placed directly under the axle.

I've gone a different direction than carrying a jack with a tandem axle trailer. I bought this and have tried it on my 31 foot long aluminum trailer with good results: Trailer Aid Tandem Tire Changing Ramp by Trailer Aid
It's available at amazon for about $46. A bit heavy and large to stow in the truck but it was very simple to very fast to use with little fear of the trailer "falling off" a jack.
This obviously wouldn't work on a single axle trailer and maybe not on a triple axle.

I like it. But us R21 owners generally have single axle trailers, so a jack is necessary. 🙂 I just use a bottle jack under the axle (with a piece of wood between) and it's always worked well. Every time I pull my trailer out of the salt chuck, I throw a bottle jack under the axles, pull the wheels off quickly, rinse everything with fresh water and then spray the brakes, lugs, etc with Fluid Film.

For the folks with Tandem axle trailers a piece of 4x4 or 6x6 wood with one edge cut on a 45 degree angle by Mr. Chain Saw to form a ramp. Back or pull up the axle without the issue up on the block and the other wheel will be magically suspended. Just remember to break the lug nuts loose before the wheel gets off the ground.

On a triple axle trailer here's what I've learned: Space your fenders up a bit more now to avoid the tire binding when the axle is elevated, place the jack under the affected axle, raising on the frame typically does not get the tire off the ground before the lifting mechanism runs out of lift, use a bottle jack with quite a bit more capacity than you mathematically need, makes it easier to operate, put a wide steel plate under the jack to keep it from mushing into the ground or asphalt.
