Check out what Larryk said about axles

I checked around and fround out that double hub was have a weight load of 750lb per axle and will not support a golf cart. I went with flexiride  by Universal Group in NJ, which I found out that  they have apair of flexiride half axles that will work out and they can carry a load of 1000 lb per axle you may have to change your mounting some.
