Jacking For Tire Change

[Bluedog]

Seems there is a lot of controversy over where to place a jack on a 2-axle travel trailer to change a single tire or service wheel bearings. Experts say under the U-bolt plate is not OK because of the danger of bending the axle. Question is how can the axle get bent when you are lifting the suspension system at the U-bolt location which is built to handle it. Same as driving the single wheel up on a 2 inch board. Some experts say to place the jack under the frame behind the wheel which appears to me to invite damage to the frame more so than the axle method. Also, this way the trailer has to be lifted quite high for the springs to extend and lift the tire off the ground. Under the U-bolt only requires a few inches to get the tire up.

Please enlighten me!

Who are these “experts” you refer to?

Use a home built wooden ramp on the good tire on a tandem axle. Safer. Faster. Easier.
