Jacking point

At the International Rally this year, a tire changing presentation stated that the best jacking point is directly between the wheels. I'm new to twin axle airstreams and would like to know you more experienced folks agree with that jacking location? The presenter did emphasize that the jack has to be carefully placed so as to exert the lifting force thru the vertical member (web) of the C channel rather than the horizontal bottom flange.
thanks for any comments

I've always used the jack point that is marked on the belly of the trailer. It is clearly marked.

Locate the jack point under your trailer. It should be marked with an arrow pointing to it. It's not 'at' the arrow, but that arrow points to it. On my rig there's a 2 inch x 2 inch square of aluminum that's riveted to the underbelly. It's right at the seam that runs along the I-beam.

When I use the marked jacking point, I can't open my entry door. This tells me that the frame is being distorted. I jack between the wheels on the axle carrier beam. I also use a 3/4" thick steel load spreader between the jack and the beam. By doing this, the load to the frame is unchanged from the load seen while towing. I think advice you got in the presentation is spot on.

I just put four new tires on my FC 30 RB. I lifted one side of the trailer at a time placing a 2.5 ton hydraulic jack between the wheels on the axle carrier beam. I removed one tire and placed a jack stand under the axle as close to the brake drum as possible. Removed the other tire and did the same with a jack stand. Went to the other side and removed the tires on that side using the same method. That way I could take all four wheels into the tire shop at one time to have the new tires mounted. Putting the wheels back on with the new tires installed was the reverse of the removal. I'm thinking that using the jack point on the trailer is the least desirable method of removing a tire. If only removing one wheel, say to change a flat tire, it's easiest to pull the good tire up on a three inch block which will lift the flat tire off of the ground - no jack needed.

jacking changing tire

I believe in simple and old school. Your working on a dual axle, so simply get 2 short pieces of 4x4 12" long, cut a 45 degree angle on one end. attach tow vehicl e and place one 4x4 in front ( or rear) of tire and drive ONE tire onto 4x4. loosen lug nuts before driving onto 4x4. Be sure to chock wheels on opposite side with 2nd 4x4 .The other tire should lift and spin freely. change tire and move off 4x4. Reverse operation for 2nd tire. Be sure to tighten lug nuts to 110 lbs with torque wrench. Easy, fast and safe.

Yes, this is what I do. I found my floor jack will not fit between the tires, so a bottle jack is the answer.
I have never used the marked jack points because I don't like laying on the ground to place the jack, also there's a water line running right over one corner.
I figure if the axle support beam can carry the trailer bouncing down the road, it will be able to support the trailer parked.
BTW, the beam is a "C" or "L" shape with a flange across the bottom. I don't need the jack right on the edge.

My local Discount Tire refused to use the marked points or the support rail. They would only jack under the axles (???) so I left.

Easiest way to change tire on tandem axle trailer

BISupply Tandem Wheel Ramp. I have carried one of these or something like it for 15 years in my tow vehicle. I have used it to lift a Airstream 25FB trailer and a 23 foot center console fishing boat to change tires.

Me too, especially a steel load spreader.

It's the steel vertical beam that the axles and shocks attach to. If you look between the tires (dual axle), you're looking at it. It's actually "C" shaped, so a bottle jack fits under it without needing to be on the edge.
(a floor jack won't fit between the tires on mine, thus a bottle jack.)

If you look between the tires, you will see a short section of steel channel that the axles are bolted to. That is what I (and others) are calling the axle carrier beam.


Use of a load spreader is recommended. I used a bottle jack on my 25 and it deformed the lower web of the channel. Since them I have always used a wood or steel load spreader between the jack and the beam.

Dredging up an old thread.

So Airstream provides a place to use a jack to lift the trailers but there isn't an AS official way to put trailers on jack stands unless you use the bottle jack w/ stand combo.

I'd like to use jack stands to remove all 4 wheels and take them in for TPMS sensors. The problem being that the jack point will be used by my jack which leave no official place to use the jack stands. AS really should provide some guidance.

i'm inclined to use a jack between the wheels as mentioned above and put the jackstands below the factory marked lift locations ... or visa versa.

These are what I've used since day 1 and have been happy with them. My Airstream is jacked up right now while I'm traveling overseas supported only by two of these combo jacks and the tongue jack to remove weight from the tires. Never have had a problem and my door opens without problem when supported like this using the factory-marked lift points.

It will come off the jacks this summer when I'm home for a trip in the Airstream and then back up as I prepare to return overseas.

I'm sold on the all-in-one so that is what I'm going with.

For the sake of discussion...


https://www.airforums.com/forums/f45...ge-244781.html post #3


I got as far as getting some left over 6x6x18 to the barn, intending on laying them horizontally for the back supports, but got waylay-ed with some medical issues. However I like the simplicity of this process....stays with the original AS jack point location & design. Besides why by jack stands...the 6x6x18's are free. Next fall for sure. The to give the tires a bit of rest.

Follow-on question about using the jack points. I can see only two of these on my Trade Wind (25', dual axle); they are to the rear of the wheels. I have never (yet) tried to jack up the trailer so I'm wondering--does raising the trailer with one of these jack points completely lift that side of the trailer so that the tires can both be removed? It seems to me that the front would also need to be raised in order to get the whole side in the air. But there are no jack points in the front.

The reason I'm asking is, I will be taking the AS to a tire shop to have the TPMS valves installed. I want to be able to competently guide the shop in lifting the trailer properly. TIA

There's always this option.
Just had 4 new tires put on at Discount Tire.
They were fine with the tiles, no Jack needed, 2 tires done at a time.

Yes - the jacking points can easily lift both tires off the ground.

Using the ramp method is much safer and easier if the trailer is still hitched to the truck though. Instead of changing two tires on one side you change both tires on an axle. Safer, less risk of damage, and quicker.
