Jacking a TT question

I have Lippert 4400lb axles and the Lippert warns against jacking on the axles. They say to only jack on the TT frame. The axles are under the leaf springs to raise the TT, I suppose to accomodate the taller trucks, and my TT frame is 2 feet from the ground. Also, there is a propane line attached to the frame on one side. Just wondering. Any suggestions?

  • If you have an owner's manual for your TT, jacking procedures for a tire change are frequently documented in the manual. Can't go wrong with the manufacturer's recommendation...............
  • Never jack under the middle of the axle. I have jacked where the ubolts are and no issues. You are lucky since you have underslung springs.
  • I have always jacked up using the spring perch. I can't say that's it proper, but what I do and never had a problem. I can understand that jacking on the axle could cause problems.
  • Not going to hurt the tire. However. Raising the good tire on a ramp, does not alway raise the flat tire. It depends on the type of axle you have. On my Fleetwood. Running the good tire on a ramp, just made the good tire higher than the flat tire. The flat, stayed firmly planted on the ground. I had to jack the bad tire up
  • Doesn't that put undue stress on the tire that you are using to "jack" the adjacent tire? I just want to be accurate.
  • Don't jack it up at all. Use your leveling materials, leggo blocks or similar materials to bild a ramp on which you drive the OPPOSITE wheel that you need to raise. One set of leggo blocks will build a pretty fine ramp for the purpose. It's not only much FASTER but much SAFER than jacking up the trailer. You can ALSO purchase a device made specifically for the purpose but never found any reason to spend %50.00 to do what is easily done for free.
  • If it is dual axle, just run one set of tires up ramps and work on the other set. Then reverse.
