Just got all new 2000 lb axle, bearing buddy hubs, leafs, hangers, brackets, hardware, new LoadStar 14 inch wheel tires...all of it. Put under a 1400 lb rig and went 3 miles.. total leaf spring failure. One went straight flat, the other looks like a "W". the W leaf sent the brand new tire into the trailer frame and fender causing a 6 in gash and massive blowout. The flat leaf cause sever rub on the the other new tires inboard sidewall with severe rubber loss and melting...tires shot. Brand new stuff from AAA Trailer Parts. Looked great going on, price was right. 2 days now trying to get some support. Luckily I was on a test run after the suspension replacement, and stuck to the frontage roads, but damn 3 miles. Will keep posted on customer support. Axle and hubs are fine, but I see them owing me leafs and another set of wheel/tire assys.
