The best designs I've seen use a stock front spindle, bearings, and hub from that model vehicle. A little heavier than those listed, but a lot of spare parts you wouldn't have to store elsewhere. I've seen the same thing used on tire carriers for the actual tire mount. Food for thought.
yah but then if you use your spare parts you have to find a way to haul your swing out rack lol.
After doing some research on tire carrier hinge systems I finally found some confirmation, in the form of pictures, spindle style hinges failing (cracking or shearing off)
Well, if someone wants to bash on spindles, that's fine. But don't bash them without offering an alternative.
Anything can break. Post up what you like and why. Don't just bash and run.
