How to jack up a trailer with torsion axles. On a dual axle with torsion axles you can easily get a block andor ramp to drive the good tireaxle on allowing you to change the wheeltire out without the need of a jack. This is safer on the side of the road given you dont need to get down on the ground with a jack. These work very good.

It didnt take much jacking to get the tires off the ground - torsion suspension doesnt droop as much as I thought it would. Once it was up I slid the jack stands around behind the wheels where the axle is closest to the frame. After gently lowering the trailer onto the stands I removed the wheels.

The procedure was repeated for the other side where I left the jack in place but not. The only other thing I could think of is a toe-lift jack or a small bottle jack. I am on my second triple torsion ae Myco and i can promise you that you cannot jack it up.

It is very simple with the blocks. Put a 4 x 4 in front of the front axle tire and one in front of the rear axle tire. Then put a 6 x 6 in fron to the first 4 x 4.

If your trailer has a torsion axle the best location to jack it up would be between the wheels with the jack on the sub-frame where the axles are attached. Another good location would be under the leaf spring mount and some owners do that very thing. Even dealers ignore some locations and place their jack stands under the axle.

If you have a Dexter Torflex Axle then you can use one of the following based on your axle capacity. If you do not have a Dexter Torflex Axle then you will need to measure from the center of the two mounting holes on your trailer axle. 2000 lb Torflex 9 or 7.

The only option I have for you to store a torsion axle trailer with the wheels off the ground is by using jack stands the Powerbuilt Unijack Bottle Jack part ALL620471 would be a good option as they have built-in bottle jacks and offer up to 21 of lift. These bottle jacks will need to be placed on all four corners of the trailer under the frame not the axle tube. NEVER jack up or lift your trailer by the axle.

Place the jack on the frame behind the axle as close to the mounting bracket as you can. Lifting the trailer by any part of the axle will bend the axle and replacement of the axle will be needed. We have two lift kit options for Dexter Axles.

We have the Torflex Lift Kit - Tandem Axle - 2-78 Lift K71-724-02 for number 11 axles or K71-725-02 for number 12 axles. This will lift your trailer by that specified amount by raising your trailer frame. The best option is for you to simply remove your torsion axles and use the Timbren Axle-Less Trailer Suspension System TASR5200S03 which is rated for 5200 lbs and has a 4 lift spindle.

With these you would need Hub and Drum Assembly 8-201-5UC3-EZ. If you are adding the torsion axles then you are probably adding a box steel sub frame to achieve the correct ride heigth. This strengthens the frame and is a good place to use a bottle jack.

I use an 8 ton bottle jack all the time for brake and wheel bearing maintenance. The best way to jack up a boat trailer with torsion axles or straight axles for that matter is to use a trailer jack that is rated high enough for the weight of the trailer at the point the jack is installed. Going with a higher capacity than needed will.

Jack a trailer at the axle tube. Obviously you can bend the axle. Doing thisdepending on where you place the jack.

I had always jacked it by the axle right at the outermost point by the spring just inside the spindlefiguring this was a good weight bearing pointand offered the most lift and no possibility of bending. My trailer came with an axle lift from the factory and I was able to slide a 2x4 through it. This serves as the place for my 2 jack stands.

I wasnt able to place the jackstands on this metal beam because it was too close to the tire. It sits very nicely in this channel. I used a small bottle jack to lift the trailer from the bracket that holds the torsion beam to the trailer.

Dexter recommends that you do not jack up the trailer on the suspension components because there is always the potential for damage. Bent hangers leaf springs or axle tubes can cause bad axle alignment with bad tire wear resulting. Put the tire ramp in front of the inflated tire.

Prepare to pull the trailer forward if you want to work on a rear tire. Do the opposite if you have a flat on a front tire. Make sure that the tow vehicle trailer and ramp are perfectly aligned.

If you have a torsion bar axle and not a leaf spring the process is going to be a little different. Torsion bar axles are harder to work with. You have to jack up a torsion axles higher than leaf spring trailers.

Use the Right Trailer Jack. Not every jack is up to the task. You need to know the weight of your trailer plus your boat.

What they really mean is dont jack under the center of the axle as you could bend it. The safest place to jack IMHO is under the U-bolt plate under the spring just behind the wheel. After all this is where the weight of the trailer actually transfers to the axles.

Done mine for years on this spot and never a problem. Put the floor jack under the leaf spring if theres sufficient area to safely put it under without pushing on the U-bolts. If that doesnt work go as close as possible to that point.

You dont want to go far inwards as it may bend your axle tube. I always put jack stands for safety under the trailer frame. Knowing how to properly jack up your dual axle trailer can save you time in an emergency situation.

It can also keep you and the contents of the trailer safe. While you can use a heavy-duty jack designed to lift the tonnage of your dual axle trailer there are tools and methods that will make the job easier quicker and safer. First do your utmost to do your lifting operations on solid level ground.

Thick gravel can cause a jack to slip which could end up in injury or damage. If youre stuck on a gravel road see if you can dig down to solid ground to seat the jack. Second chock the wheels on the side opposite youll be raising up.

For a single axle trailer the bump is really no different because the wheels just carry it over the bump. 3 points of contact always. See the image below.

The tandem axle trailer is different with 5 points of contact. Since were talking about torsion axles lets look at a trailer with Torsion Axles In Tandem. When the front set of wheels are on the bump the back.

I carry a 10 ton bottle jack and it works great. I do jack up on the axle if not I would have to jack up the trailer a long ways to get the tire off the ground. When I had a FW I had a flat and my 1 ton truck jack would not jack it up so I got a jack that would.
