Has anyone had success freeing a rusted telescoping tongue extension? I have a painted steel trailer that has launched in salt water a few times by the previous owner. Looking things over it seems like the inner square tube should slide. There is only minimal rust extending about an inch beyond the opening in the outer tube. I'm guessing there must be a considerable amount of rust inside the tube that can't be seen. I've been soaking it with penetrating oil regularly for about two months. Still will not budge. Next I'm considering a torch to heat and expand the outer tube. Any Thoughts?

tow it out
restrain the trailer, use your truck, yank it out
it is not doing you any good where it is

Ric,

Having never delt with the problem, I agree with the "soak it, heat it, beat it, tug on it" suggestions.

Rust expands the volume of carbon steel at an enormous ratio with amazing pressure. If there's much thickness to the accumulation, the situation may be hopeless. The good news is that steel tubing is not expensive, and is easy to cut and weld. Since your trailer was not galvanized to begin with, it shouldn't be too hard to cut out the damaged parts and weld in new metal with no reduction in longevity.

Another possibility might be to split the female part with a disk grinder. The intent would be to relieve enough of the rust pressure for the other methods to work. Then, depending on what you find in there, the female part could either be welded back up, or replaced.

Lots of luck!

I think I would block the tires and try to use your truck to rock it back and forth.

I think I'll try soaking a bit longer then blocking and pulling with the truck. I tried blocking and pulling and beating initially but had no luck. If that does not work it's going to be THE TORCH. The good thing is there is no hurry. The boat is in a slip and I can launch and take out at the ramp without extending the tongue. Just wanted it to work if I ever have to launch at a low angle ramp. Thanks for the suggestions.
