Paul, your post is very helpful. My rear axle just broke and per your description, it is the hubs. Judging from all of the blogs I've just read...this is a Husqvarna issue. They should not let Lowe's cost-reduce their lawn tractor for the masses and ultimately damage the Husqvarna brand. I know that I will not be buying anymore Husqvarna anything!
Having said that, can you tell me which hubs you used to repair your LGT2654?
Thanks.
