This thought keeps running thru my head. Can you bend an axle, jacking it up to change a flat tire. I sure hope not, but with these travel trailer (TT) frames being maxed out, I wonder. And No, I did not have a flat.
I would ONLY jack it up where the U bolts are. I have tandem axles so I bought the ramp that you drive on with the good tire which raises the flat tire so you can change it
The ramps come in different heights,since you have a leaf spring suspension I advise "Test It will Lift High enough" before you Really need it! I have a Ramp that I as well as other FRF members have used when they have Trailer/5 wheel tires installed at a Local Tire shop! Met 1 FRF member that had a Leaf Spring suspension at this Tire shop and my ramp was NOT high enough! I took it home and Added 2 more inches Still not enough! Test your Ramp Before Needed!! Youroo!! PS My ramp is 8" lift on top level!
