Well sorta. I have a 8.4" rear gear in an axle designed for rock climbing however 460 lbs tongue does not add 612 lbs to the axle. It adds 460lbs to the car. but it adds it in a see-saw effect so has two components: the 460 is added to the car (spread across all four wheels) and then there is a torque monent about the rear axle so the actual change is 230 added to the front and 230 added to the rear then take 152 off the front which results in the net being about 400 added to the rear and 80 to the front. I see very little change in the front (less than a 1/2", this is not exact, takes a good set of scales to know) and the rear drops about an inch.

I need to run some mre calculations but can promise that a 460lb tongue weight does not become a 600 lb load on the rear axle.

Now if you have a lot of distance between the rear axle and the hitch ball that proportion (3:1 for my TV) could change dramatically
