This is great info. Not many TMs were built with 5200 pound axles. In hindsight, I wish that more of them had been, but hindsight isn't really helpful. When the decision was made, weight and cost undoubtedly entered the equation.

I learned a valuable lesson from Larry's experience. I would have said that 3500-pound axles have 5-lug wheels, and 5200-pound axles have 6-lug wheels. This is not a reliable indicator of which axle you have. Larry has suggested that when you are buying parts, it is the hub size is what matters, not the number of lugs. So if there is any doubt, pull the hub and measure the inside diameter. The measurement will be around 10 inches for 10" hubs, and around 12 inches for 12" hubs, and this is your guide to replacement parts. Who knew?

There isn't much info available to owners with 5200 pound axles, so Larry's experience and writeup are especially valuable. Thanks, Larry.
