Keep in mind, when ordering a new axle from UFP, yeah, the axle may be $500, but that is just for the bare axle. My experience was almost comical, especially when I told the salesman I wanted to get the complete assembly. So, in addition to the axle, you need (all separate items from UFP) the trailing arms, trailing arm bolts (I bought stainless steel ones locally), axles, wheel bearing inner races, wheel bearing outer races, wheel bearings, bearing grease seals, wheels, and fenders. After that you need bolts to mount the axle to the trailer, a way to mount the fenders, and someway to protect the boat hull from rubbing the fender. All outlined in detail previously, search the forum. Total price is well over $1000.
