You just might want to check your rear axle nuts. I have 23,000 miles on my 28 sport coupe since it was redone. At the time I torqued the axle nuts at 110 ft lbs. noticed lately that there was grease on the hub cap, so finally to day I check the one with grease on the cap. It was loose, probley some one tears ago ran it loose and wore the hub and axle.
 
More likely the hub the rolling action has caused the hub to seat "tighter" on the taper, and you've now made up the difference?

Did you grease the taper before installation when it was redone?

Les Andrews recommends 125 ft-lbs. which is nearly the recommended torque for fine thread Grade 5 bolt material (Fine =128)

Some think the material spec for axles (and nuts) is BETTER than Grade 5.

My Email reply for my query on Dorman Brand axle nuts for Model A application indicated that Dorman properties are about half way between Grade 5 and Grade 8. As in torque about 154 ft-lbs?

The Dorman nuts are No. 814-066 shown at http://www.dormanproducts.com/itemdetail.aspx?ProductID=29024&SEName=814-066.
