Good information in this thread. I thought I was close to needing new axles. My axle drop on an empty trailer is 1.5". It appears obvious that they are fine. I have two 3500# axles under my 2002 Safari 25. Weighed on the scales, trailer axles with no weight distribution is 5180#. The way I read the Dexter chart is that my axles will travel 2.3" from fully loaded (3500#) to no load. So my 3500# axles are carrying about 2600# when the trailer is empty. So the axle travel will be less than 2.3" because the axles are about 75% loaded with an empty trailer. I think an 1.5" travel is good for a 13 year old trailer.

Am I looking at this wrong?

Actually, you have proven that you understand more than most about loading a Dexter Torsion Flex axle, and testing it for wear. Your assessment is on point. I hope many will read your post and understand the relationship to axle drop and load vs. no load. You described it well, and I agree that your axels are fine. My new axles on my 89 Argosy Fifth wheel (11000#) have proven to be the right choice. I replaced them in the spring and went from 4800# to 5200# axels. The contents of the trailer are in place when i stop to use it, and I notice a difference in the shock absorbing action of the trailer while towing. Good Luck.

I know that most people won't want to do this, but a short ride in the trailer will tell you more about the axles then any measurement.

Could an overloaded trailer and or dead axles lead to tire failure? If this were the case the tires would be acting as the suspension putting severe stress on them. Sorry if I hijacked the thread.

I noticed that the front curbside tire is wearing badly on the inside 2" of the tread. Could this be an axle problem?

Possibly... It could also be a bad tire, but wear on the inside is often an indication that the bottom of the wheel is cambered outward causing the load to be carried on the inner portion of the tire. Rotating the tires and observing them over time is one way to determine if the tire is the problem or if there is a something amiss with the spindle or axle alignment. Personally I would rotate the tires and replace the worn one as I've come to distrust suspect tires. I would also get the trailer weighed to verify it doesn't need to be put on a diet. If the wheel bearings check out, find a shop that can check and adjust the axle alignment. They can also determine if the arm is somehow bent... That might indicate an axle replacement is warranted. If you look under the trailer at the axle, you may see that it appears bent near the middle. This is how trailer axles are aligned and is normal. It should effect both sides equally. Unusual tire wear should be investigated to avoid a possible breakdown in the middle of nowhere.

Thanks for the reply. I am taking into the dealer next week for another issue and will have him check it out. I will let you know if I find out the problem for your knowledge.
