Jacking point for flat tire 31' Sovereign

I would think that the main frame-two rectangular beams running the length of the trailer-would be the best place to find a point to place a jack for changing a flat tire. By placing my heavy-duty hydraulic jack in a number of sensible locations,each time I attemped a lift I watched(and heard)the main frame start to fatigue. Please help,

Get some 2x6 and run the non flat wheel up on it then you can change the other one. I jack mine just behind or just ahead of the axles.

search the term jacking or 'jack points' and many threads on the topic will appear...

here is a pic johnhd posted showing how a ramp is used for lifting as wahoonc suggests...

and to change one tire of a double or triple...

http://www.airforums.com/forum...5&d=1128361020

and here is a photo from tinsel loaf, showing the best jack points...

http://www.airforums.com/forums/178629-post1.html



i questioned this since it is contrary to the owners manual...

last week when the factory raised my triple to lube the bearing...

this is EXACTLY where they placed the jack stands...

and where i will forevermore expect to place a jack...

cheers

Hi, Rozwd,

I carry a couple of ramps from Auto Zone that I bought for less than $50 to handle tire changes. On a recent trip, I used them twice.

When the tow vehicle is attached, a ramp is much faster and easier to use than a jack, although a hard surface is prefferred for using them. (Once I changed a tire on the side of US 1 on the grass and it worked okay, but I worried about it.)

My ramps were made by "Rhino" and are rated at 12,000 lbs. They don't become disfigured at all with the weight of a single wheel on them. (If you'll look in my gallery, you'll see a picture of my Excella up on one.)

Jacking on the frame rails between the axles, in my opinion, puts more stress on a localized point on the frame than using ramps, and, at least, in my 70's model, the frame is not very thick there. The axle itself spreads the lifting stress around more than a bottle jack will.

Been thinking - I have a lightweight #4,000 aluminum floor jack. Why not throw it in the back of the TV and put it under the axle bracket, if frames are so light. Better (more stable) than a bottle jack. Bad place to twink a frame!

on't need a jack to change a tire on a tandem or tri-axle Airstream trailer.

All you need is a couple of 2 x 6's.

Pull the good tire on the side that has the flat, up on it, and then change the flat tire.

Or, if you insist on using a jack, place it between the 2 tires and lift frame the axle mounting plate, but NEVER EVER from the axle tube.

I find the Lynx Levelers are useful for side to side leveling of the trailer, use under stabilizer jacks, and above all, for removing wheels. Safe and easy, and they store well and are easy to keep clean and tidy. I carry two sets of ten each.
