Not that simple, I took the old bearings and races out, replaced with new, re-installed hubs and the same problem, the hubs are worn irregular and spin but in an elliptical orbit causing the tires to wobble, need new hubs. The bearings fit a 3/4 inch spindle, no problem in obtaining the bearings, but to locate a hub that the bearings fit into, major problem. Ran around for 2 days trying to piece together enough parts to build a new axle, Tyree hardware had the 1 inch spindles, $22 each, also have the hub assembly with bearings $43 each, then run around to locate an axle, Ahrens Steel have 1 1/4inch 80 gauge round that the spindles fit into perfect, $20 for 4' 2" length, now all I need is 1 3/4 inch spring saddles for the 1 1/4 inch round, $10 each, but no one has saddles. The saddles are necessary because they mate the round to the flat and have holes that keep the axle centered on the leaf spring, can order them but will take 2 weeks.
So I took the axle with hubs to a local trailer builder and he will build me a new 3000 lb axle (cause that's all the stock he has on hand) with 1 inch spindles and hub assemblies (5 x 4.5) for $180, be ready on Monday.
Not too bad.......
